Definitions
- This invention relates to a synthetic fiber cable.
- JP Patent Application (Laid-Open No. 2000-110365) describes the insertion of a rod-shaped body, which is made of carbon fiber or aramid fiber, into a concrete structure with the aim of enhancing strength.
- An oblong hole is drilled into a reinforced-concrete pillar, and a rod-shaped body made of carbon fiber is driven into the oblong hole.
- a gap remaining in the oblong hole is subsequently filled with a fluidized curable resin, thereby fixing the rod-shaped body made of carbon fiber within the concrete.
- the rod-shaped body made of carbon fiber is merely fixed within the concrete by the fluidized curable resin that contacts the surface of the rod.
- An object of the present invention is to provide a synthetic fiber cable in which concrete or the like is allowed to penetrate the interior of a cable to thereby enlarge the area of contact with the concrete or the like, thereby making it possible to raise the efficiency of fixation.
- a further object of the present invention is to provide a synthetic fiber cable that is excellent in terms of handling, the cable flexing suitably when bent.
- the synthetic fiber cable according to the present invention is characterized by comprising: a core member having multiple resin-impregnated synthetic fibers, the fibers being bundled together; and multiple side members each having multiple resin-impregnated synthetic fibers, the fibers being bundled together in each side member; wherein the resin is in a cured state and each of the multiple side members has been shaped utilizing curability of the resin; each of the shaped multiple side members being in such a state that they are twisted together around the core member.
- the core member and side members formed by the multiple resin-impregnated synthetic fibers maintain the shape that prevails when the resin has cured.
- the resin will be cured by heating if it is a thermosetting resin and by cooling if it is a thermoplastic resin. If the resin is cured in a state in which a prescribed shape has been imparted, the core and side members will be capable of retaining this shape continuously thereafter.
- the synthetic fibers that construct the core member and side members include carbon fiber, glass fiber, boron fiber, aramid fiber, polyethylene fiber and PBO (polyp-phenylenebenzobisoxazole) fiber, as well as other fibers. These fibers are extremely slender and can be impregnated with resin by bundling a number of these synthetic fibers.
- the synthetic fiber cable is constructed by placing each of the multiple side members, which have been shaped beforehand by utilizing the curability of the above-mentioned resin, in a state in which they are twisted together around the core member.
- suitable spaces or gaps can be assured in the interior of the synthetic fiber cable, specifically between the core member and its surrounding side members as well as between mutually adjacent side members, without impairing the substantially twisted state of the side members.
- the synthetic fiber cable according to the present invention is suitable for use as, for example, an electrical transmission cable (power transmission line), optical fiber cable, submarine cable and other comparatively long members (elongated objects), and as reinforcement for equipment.
- the core member and each of the multiple side members have, along the longitudinal direction thereof (there exist along the longitudinal direction), both contact portions where the side member is in contact with the core member and non-contact portions where the side member is not in contact with the core member. That is, the multiple side members surrounding the core member are not in continuous contact with the core member along their full length in the longitudinal direction but rather have portions which are not in contact the core member (portions where the side member is spaced away from the core member).
- the synthetic fiber cable is prevented from losing its shape owing to the contact portions. Because the non-contact portions define spaces between the core member and the side members, they contribute to improved bending ease (pliability) of the cable and are useful in facilitating the penetration of concrete, mortar or other coagulants or setting agents. For example, when the synthetic fiber cable is embedded in concrete, the concrete will penetrate into the interior of the synthetic fiber cable and the cable will be fixed firmly inside the concrete.
- the synthetic fiber cable according to the present invention is suitable for use as reinforcement for concrete structures, by way of example.
- each of the multiple side members each has, along the longitudinal direction thereof, both contact portions in contact with mutually adjacent side members and non-contact portions not in contact with the mutually adjacent side members. That is, the multiple side members surrounding the core member are not in continuous contact with adjacent side members along their full length in the longitudinal direction but rather have portions which do not contact the adjacent side members (there are gaps between the side members).
- the synthetic fiber cable is prevented from losing its shape owing to the contact portions.
- the non-contact portions contribute to improved bending ease (pliability) of the cable and are useful in facilitating the penetration of concrete, mortar or other coagulants or setting agents.
- the contact portions and non-contact portions between the core member and the side members as well as the contact portions and non-contact portions between mutually adjacent side members, it is preferred that the contact portions and non-contact portions be present repeatedly along the longitudinal direction.
- a synthetic fiber cable that is readily pliable along its full length. In a case where this synthetic fiber cable is used in a concrete structure, internal spaces that allow the penetration of concrete can be assured in dispersed fashion along the longitudinal direction of the synthetic fiber cable, and entrances that allow the penetration of concrete from the exterior to the interior can be assured in dispersed fashion.

- FIG. 4 is an enlarged sectional view taken along line IV-IV of FIG. 1 ;
- FIG. 5 is an enlarged sectional view taken along line V-V of FIG. 1 ;
- FIG. 6 is a graph illustrating results of a concrete pull-out test.
- FIG. 1 illustrates the external appearance of a carbon fiber cable.
- FIG. 2 is an exploded perspective view of the carbon fiber cable.
- FIGS. 3 to 5 are enlarged sectional views of the carbon fiber cable taken along lines IV-IV and V-V, respectively, of FIG. 1 .
- a carbon fiber cable 1 is constituted by a single core member 2 as well as six side members 3 ( 3 a to 3 f ) (a 1 ⁇ 7 structure) placed in such a state that the side members are twisted together around the core member.
- the carbon fiber cable 1 , core member 2 and side members 3 all have a substantially circular shape.
- the carbon fiber cable 1 is such that the core member 2 is placed at the center thereof while the six side members 3 are situated so as to surround the core member 2 .
- the carbon fiber cable 1 has a diameter of 5 to 20 mm, by way of example.
- the core member 2 and side members 3 each comprise a large number, e.g., tens of thousands, of long carbon fibers 4 impregnated with a thermosetting resin (epoxy resin, for example) 5 and bundled into a shape having a circular cross section.
- the overall carbon fiber cable 1 includes on the order of several hundred thousand of the carbon fibers 4 .
- Each of the carbon fibers 4 is very slender and has a diameter of 5 to 7 ⁇ m, by way of example.
- the core member 2 and side members 3 may each be formed by bundling together the large number of carbon fibers 4 impregnated with the thermosetting resin 5 and twisting together a plurality of these bundles of carbon fiber.
- the core member 2 and side members 3 can also be referred to carbon fiber reinforced plastics (CFRP).
- the core member 2 and side members 3 employed have the same thickness (cross-sectional area).
- the side members 3 used may of course be thinner or thicker than the core member 2 .
- the thickness of the core member 2 and of each of the side members 3 can be adjusted at will depending upon the number of carbon fibers 4 .
- the core member 2 and side members 3 constituting the carbon fiber cable 1 are all used in a state in which the thermosetting resin 5 has been heated and cured in advance.
- the carbon fiber cable 1 is produced by placing the side members 3 , hardened by utilizing the thermal curability of the thermosetting resin 5 , in such a state that they are disposed and twisted together around the core member 2 which, similarly, has been hardened by utilizing the thermal curability of the thermosetting resin 5 . Since the thermosetting resin 5 of the core member 2 and of each of the side members 3 has cured, suitable slippage is allowed between the core member 2 and surrounding side members 3 and between the side members 3 that are adjacent each other.
- the six side members 3 that will be placed in a state in which they are twisted together around the core member 2 are all shaped into a helical configuration beforehand; the core member 2 , on the other hand, does not undergo helical shaping. It goes without saying that the side members 3 are shaped into the helical configuration before the thermosetting resin 5 is thermally cured.
- the pitch of the helix of each of the helically shaped side members is substantially the same, and the inner diameter of the helix of each of the side members 3 is substantially equal to the diameter of the core member 2 .
- Each of the side members 3 partially has portions (referred to as “bulged portions” below) shaped so as to bulge slightly outward. Bulged portions 3 A to 3 D at four locations are illustrated in somewhat emphasized form on the carbon fiber cable 1 shown in FIG. 1 .
- FIG. 3 when the portion having the bulged portion 3 A is viewed in cross section, it will be seen that one side member (side member 3 a ) among the six side members 3 a to 3 f around the core member 2 is not in contact with the core member 2 but is positionally displaced outwardly away from the core member 2 .
- the pre-shaping of the side member 3 a is carried out so as to give rise to this positional displacement. Owing to the fact that the side member 3 a is spaced away from the core member 2 , an internal space (non-contact portion) 11 is assured between the core member 2 and side member 3 a.
- an approximately triangular space (indicated at reference numeral 20 ), when viewed in cross section, is formed by the core member 2 , the side member 3 c and the side member 3 d ].
- the internal space 11 referred to in this specification does not mean the space 20 having the approximately triangular cross section but rather signifies the space between the core member 2 and each of the core members 3 , this internal space being assured by the pre-shaping of the core members 3 .
- the two spaces 20 having the approximately triangular cross section are connected.
- the side member 3 a situated between the two side members 3 b, 3 f on either side is in contact with the one side member 3 f but is not in contact with the other side member 3 b and is positionally displaced away from the side member 3 b (shaping of the side member 3 a being performed in advance so as to give rise to this positional displacement).
- a gap 12 is assured between the side member 3 a and the side member 3 b owing to the fact that the side member 3 a is spaced away from the side member 3 b.
- FIG. 4 when a portion having the other bulged portion 3 B is viewed in cross section, it will be seen that two side members (side members 3 e, 3 f ) among the six side members 3 a to 3 f around the core member 2 are not in contact with the core member 2 . Instead, internal spaces 11 are assured between the core member 2 and the side members 3 e, 3 f. Since the side members 3 e, 3 f are adjacent each other, the two internal spaces 11 are connected, resulting in the formation of a large internal space. Further, although the other side member 3 c is in contact with the core member 2 , it is situated spaced away from both of the two side members 3 b, 3 d situated on either side of the side member 3 c. Thus the gaps 12 are assured on both sides of the side member 3 c.
- the internal spaces 11 are illustrated as closed spaces. However, the internal spaces 11 are not spaces completely cut off from the outside but rather are open spaces in communication with the outside. Specifically, the internal spaces 11 assured between the core member 2 and side members 3 are connected to the above-mentioned gaps 12 that are assured by the fact that two mutually adjacent side members are spaced away at other locations along the longitudinal direction of the carbon fiber cable 1 . The internal spaces 11 are in communication with the outside through the gaps 12 .
- FIG. 5 when the portion having the bulged portions 3 C, 3 D is viewed in cross section, it will be seen that four side members (side members 3 b, 3 c, 3 e, 3 f ) among the six side members 3 a to 3 f around the core member 2 are not in contact with the core member 2 , thereby assuring internal spaces 11 . Further, gaps 12 are assured between side members 3 a and 3 b, between side members 3 c and 3 d, between side members 3 e and 3 f, and between side members 3 f and 3 a.
- the carbon fiber cable 1 is such that the locations and numbers of internal spaces 11 and gaps 12 differ depending upon the location where the cross section is taken. Naturally, depending upon where the cross section is taken, there will be instances where the internal spaces 11 and gaps 12 do not appear at all and, conversely, there can be instances where the six side members 3 will not be in contact with the core member 2 over its entire circumference. Further, as illustrated in FIGS. 3 to 5 , the sizes of the internal spaces 11 and gaps 12 (the distances between the core member 2 and side members 3 and the distances between mutually adjacent side members 3 ) that appear in a cross section will vary. This means that the extent of the multiple bulged portions 3 A to 3 D varies. It should be noted that extremely large bulged portions (internal spaces 11 and gaps 12 ) do not exist in the carbon fiber cable 1 and, hence, the essentially twisted state is not impaired.

- the bulged portion may be provided at prescribed intervals, or provided randomly, on each side member along the longitudinal direction thereof. Although the bulged portion may be provided at identical intervals on all of the side members 3 along the longitudinal direction thereof, the intervals of the bulged portions along the longitudinal direction may be made different for every side member 3 .

Description
- This application is a Continuation Application of PCT International Application No. PCT/JP2016/069283 filed on Jun. 29, 2016, the entire disclosure of the application being considered part of the disclosure of this application and hereby incorporated by reference.
- This invention relates to a synthetic fiber cable.
- JP Patent Application (Laid-Open No. 2000-110365) describes the insertion of a rod-shaped body, which is made of carbon fiber or aramid fiber, into a concrete structure with the aim of enhancing strength.
- An oblong hole is drilled into a reinforced-concrete pillar, and a rod-shaped body made of carbon fiber is driven into the oblong hole. A gap remaining in the oblong hole is subsequently filled with a fluidized curable resin, thereby fixing the rod-shaped body made of carbon fiber within the concrete. The rod-shaped body made of carbon fiber is merely fixed within the concrete by the fluidized curable resin that contacts the surface of the rod.
- An object of the present invention is to provide a synthetic fiber cable in which concrete or the like is allowed to penetrate the interior of a cable to thereby enlarge the area of contact with the concrete or the like, thereby making it possible to raise the efficiency of fixation.
- A further object of the present invention is to provide a synthetic fiber cable that is excellent in terms of handling, the cable flexing suitably when bent.
- The synthetic fiber cable according to the present invention is characterized by comprising: a core member having multiple resin-impregnated synthetic fibers, the fibers being bundled together; and multiple side members each having multiple resin-impregnated synthetic fibers, the fibers being bundled together in each side member; wherein the resin is in a cured state and each of the multiple side members has been shaped utilizing curability of the resin; each of the shaped multiple side members being in such a state that they are twisted together around the core member.
- By curing the resin, the core member and side members formed by the multiple resin-impregnated synthetic fibers maintain the shape that prevails when the resin has cured. The resin will be cured by heating if it is a thermosetting resin and by cooling if it is a thermoplastic resin. If the resin is cured in a state in which a prescribed shape has been imparted, the core and side members will be capable of retaining this shape continuously thereafter.
- The synthetic fibers that construct the core member and side members (not natural fibers such as of cotton or silk but fibers made from chemically synthesized polymer) include carbon fiber, glass fiber, boron fiber, aramid fiber, polyethylene fiber and PBO (polyp-phenylenebenzobisoxazole) fiber, as well as other fibers. These fibers are extremely slender and can be impregnated with resin by bundling a number of these synthetic fibers.
- The synthetic fiber cable is constructed by placing each of the multiple side members, which have been shaped beforehand by utilizing the curability of the above-mentioned resin, in a state in which they are twisted together around the core member. In accordance with the present invention, owing to the pre-shaping of the side members utilizing the curability of the resin, suitable spaces or gaps can be assured in the interior of the synthetic fiber cable, specifically between the core member and its surrounding side members as well as between mutually adjacent side members, without impairing the substantially twisted state of the side members.
- Owing to the fact that the core member and surrounding side members constituting the synthetic fiber cable are in such a state that the resin has cured on each member, slipping (shift in position) is allowed between the core member and surrounding side members as well as between mutually adjacent side members. As a result, there is provided a synthetic fiber cable which readily undergoes suitable flexing when bending is applied, and which excels in handling ease. For example, a synthetic fiber cable of great length can be put into compact form by being wound upon a small-diameter reel, thereby making handling easy at the workplace. The synthetic fiber cable according to the present invention is suitable for use as, for example, an electrical transmission cable (power transmission line), optical fiber cable, submarine cable and other comparatively long members (elongated objects), and as reinforcement for equipment.
- In an embodiment, with regard to the core member and each of the multiple side members, they have, along the longitudinal direction thereof (there exist along the longitudinal direction), both contact portions where the side member is in contact with the core member and non-contact portions where the side member is not in contact with the core member. That is, the multiple side members surrounding the core member are not in continuous contact with the core member along their full length in the longitudinal direction but rather have portions which are not in contact the core member (portions where the side member is spaced away from the core member). The synthetic fiber cable is prevented from losing its shape owing to the contact portions. Because the non-contact portions define spaces between the core member and the side members, they contribute to improved bending ease (pliability) of the cable and are useful in facilitating the penetration of concrete, mortar or other coagulants or setting agents. For example, when the synthetic fiber cable is embedded in concrete, the concrete will penetrate into the interior of the synthetic fiber cable and the cable will be fixed firmly inside the concrete. The synthetic fiber cable according to the present invention is suitable for use as reinforcement for concrete structures, by way of example.
- In another embodiment, with regard to each of the multiple side members, each has, along the longitudinal direction thereof, both contact portions in contact with mutually adjacent side members and non-contact portions not in contact with the mutually adjacent side members. That is, the multiple side members surrounding the core member are not in continuous contact with adjacent side members along their full length in the longitudinal direction but rather have portions which do not contact the adjacent side members (there are gaps between the side members). The synthetic fiber cable is prevented from losing its shape owing to the contact portions. The non-contact portions contribute to improved bending ease (pliability) of the cable and are useful in facilitating the penetration of concrete, mortar or other coagulants or setting agents.
- With regard to the contact portions and non-contact portions between the core member and the side members as well as the contact portions and non-contact portions between mutually adjacent side members, it is preferred that the contact portions and non-contact portions be present repeatedly along the longitudinal direction. Thus is provided a synthetic fiber cable that is readily pliable along its full length. In a case where this synthetic fiber cable is used in a concrete structure, internal spaces that allow the penetration of concrete can be assured in dispersed fashion along the longitudinal direction of the synthetic fiber cable, and entrances that allow the penetration of concrete from the exterior to the interior can be assured in dispersed fashion.

FIG. 1 illustrates the external appearance of a carbon fiber cable.FIG. 2 is an exploded perspective view of the carbon fiber cable.FIGS. 3 to 5 are enlarged sectional views of the carbon fiber cable taken along lines IV-IV and V-V, respectively, ofFIG. 1 . - A
carbon fiber cable 1 is constituted by asingle core member 2 as well as six side members 3 (3 a to 3 f) (a 1×7 structure) placed in such a state that the side members are twisted together around the core member. When viewed in cross section, thecarbon fiber cable 1,core member 2 andside members 3 all have a substantially circular shape. Further, when viewed in cross section, thecarbon fiber cable 1 is such that thecore member 2 is placed at the center thereof while the sixside members 3 are situated so as to surround thecore member 2. Thecarbon fiber cable 1 has a diameter of 5 to 20 mm, by way of example. - The
core member 2 andside members 3 each comprise a large number, e.g., tens of thousands, oflong carbon fibers 4 impregnated with a thermosetting resin (epoxy resin, for example) 5 and bundled into a shape having a circular cross section. The overallcarbon fiber cable 1 includes on the order of several hundred thousand of thecarbon fibers 4. Each of thecarbon fibers 4 is very slender and has a diameter of 5 to 7 μm, by way of example. Thecore member 2 andside members 3 may each be formed by bundling together the large number ofcarbon fibers 4 impregnated with thethermosetting resin 5 and twisting together a plurality of these bundles of carbon fiber. Thecore member 2 andside members 3 can also be referred to carbon fiber reinforced plastics (CFRP). - In this embodiment, the
core member 2 andside members 3 employed have the same thickness (cross-sectional area). Theside members 3 used may of course be thinner or thicker than thecore member 2. The thickness of thecore member 2 and of each of theside members 3 can be adjusted at will depending upon the number ofcarbon fibers 4. - The
core member 2 andside members 3 constituting thecarbon fiber cable 1 are all used in a state in which thethermosetting resin 5 has been heated and cured in advance. Specifically, thecarbon fiber cable 1 is produced by placing theside members 3, hardened by utilizing the thermal curability of thethermosetting resin 5, in such a state that they are disposed and twisted together around thecore member 2 which, similarly, has been hardened by utilizing the thermal curability of thethermosetting resin 5. Since the thermosetting resin 5 of thecore member 2 and of each of theside members 3 has cured, suitable slippage is allowed between thecore member 2 and surroundingside members 3 and between theside members 3 that are adjacent each other. - With reference to
FIG. 2 , the sixside members 3 that will be placed in a state in which they are twisted together around thecore member 2 are all shaped into a helical configuration beforehand; thecore member 2, on the other hand, does not undergo helical shaping. It goes without saying that theside members 3 are shaped into the helical configuration before thethermosetting resin 5 is thermally cured. The pitch of the helix of each of the helically shaped side members is substantially the same, and the inner diameter of the helix of each of theside members 3 is substantially equal to the diameter of thecore member 2. - Each of the
side members 3 partially has portions (referred to as “bulged portions” below) shaped so as to bulge slightly outward.Bulged portions 3A to 3D at four locations are illustrated in somewhat emphasized form on thecarbon fiber cable 1 shown inFIG. 1 . - Referring now to
FIG. 3 , when the portion having the bulgedportion 3A is viewed in cross section, it will be seen that one side member (side member 3 a) among the sixside members 3 a to 3 f around thecore member 2 is not in contact with thecore member 2 but is positionally displaced outwardly away from thecore member 2. The pre-shaping of theside member 3 a is carried out so as to give rise to this positional displacement. Owing to the fact that theside member 3 a is spaced away from thecore member 2, an internal space (non-contact portion) 11 is assured between thecore member 2 andside member 3 a. - Since the
core member 2 andside members 3 all have a circular cross section, portions of non-contact inevitably exist between thecore member 2 andside members 3. [For example, inFIG. 3 , an approximately triangular space (indicated at reference numeral 20), when viewed in cross section, is formed by thecore member 2, theside member 3 c and theside member 3 d]. However, theinternal space 11 referred to in this specification does not mean thespace 20 having the approximately triangular cross section but rather signifies the space between thecore member 2 and each of thecore members 3, this internal space being assured by the pre-shaping of thecore members 3. By assuring theinternal space 11, the twospaces 20 having the approximately triangular cross section are connected. - In
FIG. 3 , theside member 3a situated between the twoside members side member 3 f but is not in contact with theother side member 3 b and is positionally displaced away from theside member 3 b (shaping of theside member 3 a being performed in advance so as to give rise to this positional displacement). Agap 12 is assured between theside member 3 a and theside member 3 b owing to the fact that theside member 3 a is spaced away from theside member 3 b. - Referring now to
FIG. 4 , when a portion having the other bulgedportion 3B is viewed in cross section, it will be seen that two side members (side members side members 3 a to 3 f around thecore member 2 are not in contact with thecore member 2. Instead,internal spaces 11 are assured between thecore member 2 and theside members side members internal spaces 11 are connected, resulting in the formation of a large internal space. Further, although theother side member 3 c is in contact with thecore member 2, it is situated spaced away from both of the twoside members side member 3 c. Thus thegaps 12 are assured on both sides of theside member 3 c. - In
FIG. 4 , theinternal spaces 11 are illustrated as closed spaces. However, theinternal spaces 11 are not spaces completely cut off from the outside but rather are open spaces in communication with the outside. Specifically, theinternal spaces 11 assured between thecore member 2 andside members 3 are connected to the above-mentionedgaps 12 that are assured by the fact that two mutually adjacent side members are spaced away at other locations along the longitudinal direction of thecarbon fiber cable 1. Theinternal spaces 11 are in communication with the outside through thegaps 12. - Referring now to
FIG. 5 , when the portion having the bulgedportions side members side members 3 a to 3 f around thecore member 2 are not in contact with thecore member 2, thereby assuringinternal spaces 11. Further,gaps 12 are assured betweenside members side members side members side members - Thus, the
carbon fiber cable 1 is such that the locations and numbers ofinternal spaces 11 andgaps 12 differ depending upon the location where the cross section is taken. Naturally, depending upon where the cross section is taken, there will be instances where theinternal spaces 11 andgaps 12 do not appear at all and, conversely, there can be instances where the sixside members 3 will not be in contact with thecore member 2 over its entire circumference. Further, as illustrated inFIGS. 3 to 5 , the sizes of theinternal spaces 11 and gaps 12 (the distances between thecore member 2 andside members 3 and the distances between mutually adjacent side members 3) that appear in a cross section will vary. This means that the extent of the multiple bulgedportions 3A to 3D varies. It should be noted that extremely large bulged portions (internal spaces 11 and gaps 12) do not exist in thecarbon fiber cable 1 and, hence, the essentially twisted state is not impaired. - The bulged portions mentioned above are formed repeatedly along the longitudinal direction of the
carbon fiber cable 1. That is, with regard to thecore member 2 and each of themultiple side members 3, contact portions where theside members 3 are in contact with the core member 2 (portions where theinternal spaces 11 do not exist) and non-contact portions where theside members 3 are not in contact with the core member 2 (portions where theinternal spaces 11 do exist) appear repeatedly along the longitudinal direction. Similarly, with regard toside members 3 that are adjacent each other, contact portions (portions where thegaps 12 do not exist) and non-contact portions (portions where thegaps 12 do exist) appear repeatedly along the longitudinal direction. - The bulged portion may be provided at prescribed intervals, or provided randomly, on each side member along the longitudinal direction thereof. Although the bulged portion may be provided at identical intervals on all of the
side members 3 along the longitudinal direction thereof, the intervals of the bulged portions along the longitudinal direction may be made different for everyside member 3. The bulged portions thus are provided on thecarbon fiber cable 1 in dispersed fashion and theinternal spaces 11 andgaps 12 along the longitudinal direction of thecarbon fiber cable 1 are present in dispersed fashion. - As set forth above, since the
carbon fiber cable 1 is such that thethermosetting resin 5 on thecore member 2 and on each of theside members 3 has cured, slippage is allowed between thecore member 2 andside members 3 and betweenside members 3 that are adjacent each other. Furthermore, since the cable has theinternal spaces 11 andgaps 12, it undergoes suitable flexing when bent and excels in handling ease. The cable can be put into compact form by being wound upon a small-diameter reel, thereby making handling easy at the workplace. For example, thecarbon fiber cable 1 is suitable for use as the core material of a long object such as a power transmission line. - Further, the
carbon fiber cable 1 can be used as reinforcement for concrete structures, by way of example. When thecarbon fiber cable 1 is embedded in concrete before the concrete sets (fresh concrete), the concrete penetrates into interior of thecarbon fiber cable 1 with thegaps 12 between mutuallyadjacent side members 3 serving as entrances. Concrete that has entered into the interior of thecarbon fiber cable 1 from thegaps 12 enters theinternal spaces 11 assured between thecore member 2 andside members 3, resulting in greater area of contact between thecarbon fiber cable 1 and the concrete. Naturally, depending upon such factors as the viscosity of the fresh concrete and the sizes of theinternal spaces 11 andgaps 12, the concrete may not fill theinternal spaces 11 completely. However, in addition to the fact that the concrete comes into contact with the outer periphery (surface) of thecarbon fiber cable 1, contact with the concrete also occurs in the interior of thecarbon fiber cable 1 as well. Hence an increase in the area of contact between the concrete and thecarbon fiber cable 1 is achieved. As a consequence, adhesion stress can be improved greatly in comparison with iron reinforcing bars and thecarbon fiber cable 1 can be fixed inside the concrete with a high degree of fixing efficiency. Concrete structures include bridge beams, piers, bridge rails, protective barriers and the like. -
FIG. 6 is a graph illustrating results of a concrete pull-out test in which the horizontal axis is a plot of slip displacement (mm) and the vertical axis a plot of adhesion stress (N/mm2). The solid line in the graph indicates the result of testing the above-describedcarbon fiber cable 1, and the broken line indicates the result of testing a carbon fiber cable that does not have theinternal spaces 11 andgaps 12. The diameters of the core members, side members, number and structure thereof, as well as the length embedded (the length fixed) in concrete were measured under identical conditions. - The concrete pull-out test was conducted in line with the “Method of Testing Adhesion Strength between Continuous Fiber Reinforcing Material and Concrete by Pull-out Test” of the Japan Society of Civil Engineers. According to this test, a concrete block in which the intermediate portion of a carbon fiber cable has been embedded with both ends of the cable exposed to the outside is fabricated. By using a tensile testing machine, a tensile load is applied at a prescribed loading rate to the carbon fiber cable projecting to the outside from one end of the concrete block, and a displacement gauge is used to measure the amount of displacement (slip displacement) of the carbon fiber cable projecting to the outside from the other end of the concrete block.
- Adhesion stress τ(N/mm2) was calculated using the following equation:
-
Adhesion stress τ=P/u·L - where P represents tensile load (kN), u the nominal circumference (mm) of the carbon fiber cable and L the adhesion length (mm) with respect to the concrete block.
- As a result of the concrete pull-out test, it was confirmed that, in comparison with the adhesion stress (the broken line) of the carbon fiber cable devoid of the
internal spaces 11 andgaps 12, the adhesion stress (the solid line) of the above-describedcarbon fiber cable 1 is greatly improved and exhibits a high concrete fixation efficiency. - The degree of shaping of the side members 3 (the degree of constraint due to the side members 3) in the
carbon fiber cable 1 can be expressed by D/(σ1A+σ2)×100(%) (referred to as “shaping ratio” below) using diameter D of thecable 1 and diameters σ1 and σ2 of thecore member 2 andside members 3, respectively, that constitute thecable 1. If the shaping ratio is on the order of 100.1 to 105(%), thecarbon fiber cable 1 will undergo suitable flexing when bent, and the concrete adhesion efficiency will rise as well. In cases where the emphasis is placed on concrete adhesion efficiency and the concrete adhesion efficiency is to be raised, themultiple side members 3 may be shaped so as to take on a shaping ratio on the order to 110%, by way of example. - In the embodiment set forth above, an example is described in which bundles of the
multiple carbon fibers 4 are impregnated with thethermosetting resin 5 and thecarbon fiber cable 1 is constructed from thecore member 2 andside members 3 hardened by applying heat to thethermosetting resin 5. However, a thermoplastic resin (polyamide, for example) may used instead of thethermosetting resin 5. Further, instead of carbon fiber, glass fiber, boron fiber, aramid fiber, polyethylene fiber and PBO (polyp-phenylenebenzobisoxazole) fiber, as well as other synthetic fibers, can be used.
