  Hereinafter, embodiments of a metal-fiber-reinforced resin bonding member of the present invention and a method of manufacturing the same will be described in detail with reference to the drawings. In addition, the following embodiment and its example of illustration are an example of a metal-fiber reinforced resin joint member and its manufacturing method to the last, and design matters, such as a shape and a size, or the number of lamination of reinforcing fiber cloth, are appropriate or arbitrary. It can be set.

  FIGS. 1-4 is explanatory drawing which shows 1st Embodiment of the metal-fiber-reinforced-resin joining member of this invention, and its manufacturing method. Specifically, FIG. 1 is a perspective view of a metal member 14 and a reinforcing fiber fabric 12 showing a first embodiment of a metal-fiber reinforced resin joint member and a method of manufacturing the same, and FIG. 2 is a metal member 14 of FIG. 3 is an explanatory view of the coating of the metal member 14 and the reinforcing fiber fabric 12 of FIG. 1 with the resin member 18, and FIG. 4 is the resin member 18 coated with the resin member 18 of FIG. It is a perspective view of a metal-fiber reinforced resin joining member. The respective drawings are schematically represented, and in particular, the resin members 18 in FIGS. 3 and 4 are drawn in an exaggerated manner.

  In this embodiment, for example, a metal member 14 made of a metal body is bonded to one end portion in the longitudinal direction of the longitudinally long fiber reinforced resin body 10 to constitute a metal-fiber reinforced resin joint member. A longitudinally reinforcing fiber fabric 12 made of, for example, a woven fabric of carbon fibers (reinforcing fibers) is embedded in the longitudinally fiber-reinforced resin body 10 in the same manner as existing CFRP. The longitudinally reinforcing fiber fabric 12 is impregnated with a resin (resin member 18) to form a longitudinally fiber-reinforced resin body 10. In the example of the reinforcing fiber fabric 12, the fabric is configured by weaving reinforcing fibers in the longitudinal direction of the fabric and the direction orthogonal thereto. Hereinafter, the fiber direction orthogonal to the longitudinal direction of the longitudinal reinforcing fiber fabric 12 (the fiber reinforced resin body 10 is also the same) is taken as the width direction, and the front and back direction of the fabric is taken as the front and back direction.

  In this embodiment, as shown in FIG. 1 (a), a plurality of reinforcing fiber bundles (reinforcing fiber bundles) 22 constituting the cloth (7 in the figure) are provided at one longitudinal end of the longitudinal reinforcing fiber fabric 12. ) It has been erected. The plurality of reinforcing fiber bundles 22 in this embodiment are arranged alternately in the order of long, short, long. In addition, the protrusion dimensions of the reinforcing fiber bundle 22 are the same for large ones, large ones and small ones for small ones. In addition, all may be sufficient as the protrusion dimension of the said reinforcement fiber bundle 22 substantially the same dimension.

  On the other hand, the metal member 14 in this embodiment is formed of a rectangular metal plate having a width of at least the width direction of the reinforcing fiber fabric 12. The metal member 14 made of this metal plate material has a relatively small thickness. Of the metal member 14, an end portion to which the fiber reinforced resin body 10 is bonded is used as an engaging portion 16 for engaging the reinforcing fiber fabric 12, and a through hole corresponding to the formation site of the reinforcing fiber bundle 22. 20 are formed in two rows from the end and arranged in a staggered manner. More specifically, of the reinforcing fiber bundles 22 of the reinforcing fiber fabric 12 to be engaged, the through holes 20 corresponding to the reinforcing fiber bundles 22 having a large protrusion size are metal members to which the reinforcing fiber fabric 12 is engaged. The through holes 20 corresponding to the reinforcing fiber bundle 22 which is formed at a position farther than the end of 14 and which has a small protrusion dimension are formed at a close position.

  And in this embodiment, as shown in FIG. 1 (b), the reinforcing fiber bundles 22 of the reinforcing fiber cloth 12 are inserted from one side into each of the through holes 20 arranged in two rows in a staggered manner. . For example, as clearly shown in the cross-sectional view of FIG. 2, for example, the reinforcing fiber bundles 22 formed long and short from one surface of the plate-like metal member 14, ie, the upper surface in the drawing, are inserted into the corresponding through holes 20 The protruding end of each reinforcing fiber bundle 22 is engaged with the other surface of the metal member 14, in the drawing, the lower surface in a hooked manner. Thereby, for example, a frictional force acts between the corner of the through hole 20 and the reinforcing fiber bundle 22. As well known, since the reinforcing fiber bundle has a large restoring force, simply by hooking the reinforcing fiber bundle on the upper and lower surfaces of the metal member 14 through the through hole 20, a large frictional force is generated between the reinforcing fiber bundle and the metal member 14. The frictional force causes the reinforcing fiber bundle 22, ie, the reinforcing fiber fabric 12, to be engaged with the metal member 14.

  Thus, when the reinforcing fiber fabric 12 is engaged with the engaging portion 16 of the metal member 14, the reinforcing fiber fabric 12 and the metal member 14 are made of gold as shown in FIG. Set in the mold 40. The mold 40 is for injecting a resin, and comprises, for example, an upper mold 40a and a lower mold 40b. A seal 41 is interposed between the metal member 14 and the mold 40 to prevent the resin from leaking. In this state, the resin is injected into the mold 40 using, for example, a known method such as RTM (Resin Transfer Molding). For example, epoxy, nylon, polyurethane resin and the like are used for this resin, which is generally called a matrix. When the injected resin is cured, the mold 40 is released as shown in FIG. 3 (b). As a result, as shown in FIG. 4, the fiber reinforced resin body in a state where at least the engaging portion 16 of the reinforcing fiber fabric 12 and the metal member 14 is covered with the resin member 18 and the resin member 18 is impregnated with the reinforcing fiber fabric 12. As a result, the metal-fiber-reinforced resin bonding member is completed.

  Generally, when manufacturing separately the metal member which consists of a metal body, and the fiber reinforced resin member which consists of a fiber reinforced resin body, and joining them, an adhesive agent and a mechanical fastening means are used, for example. For example, a bolt-nut or the like is used as the mechanical fastening means. However, the main purpose of using a fiber-reinforced resin body is weight reduction, while using mechanical fastening means such as a bolt-nut having a large weight contradicts the main purpose of using a fiber-reinforced resin body. In that respect, bonding by an adhesive does not involve a considerable increase in weight, but often has insufficient adhesive strength.

  On the other hand, in this embodiment, the reinforcing fiber fabric 12 is engaged with the engaging portion 16 of the metal member 14 made of a metal body, and at least the engaging portion 16 is covered with the resin member 18 in that state. The reinforcing fiber cloth 12 is impregnated with 18 to form a fiber reinforced resin body 10. Therefore, not only the engaging portion 16 between the reinforcing fiber fabric 12 and the metal member 14 is covered and fixed by the resin member 18, but also the reinforcing fiber fabric 12 itself is engaged with the metal member 14, so that a simple configuration is provided. Thus, the bonding strength between the metal member 14 and the fiber reinforced resin body 10 is improved.

  Further, by forming the engaging portion 16 by providing the through hole 20 through which the reinforcing fiber bundle 22 of the reinforcing fiber fabric 12 is inserted, the reinforcing fiber fabric can be obtained only by inserting the reinforcing fiber bundle of the reinforcing fiber fabric 12 into the through hole 20 Since the member 12 can be engaged with the metal member 14, the engaging portion 16 can be simply configured.

  5 and 6 show a modification of the first embodiment of the metal-fiber-reinforced resin bonding member of the present invention and the method of manufacturing the same. Specifically, FIG. 5 is a perspective view of a metal member 14 and a reinforcing fiber fabric 12 showing a modification of the first embodiment of the metal-fiber-reinforced resin joint member and the method of manufacturing the same, and FIG. FIG. 5 is a cross-sectional view of a state in which the reinforcing fiber fabric 12 is engaged with the metal member 14; In this modification, as shown in FIG. 5 (a), a plurality (7 in the drawing) of reinforcing fiber bundles 22 having the same projection size are provided at one end of the longitudinal reinforcing fiber cloth 12 in the longitudinal direction. . On the other hand, in the metal member 14 in this modification, the joint end of the fiber reinforced resin body 10 is penetrated corresponding to the formation site of the reinforcing fiber bundle 22 as the engaging portion 16 for engaging the reinforcing fiber cloth 12 Holes 20 are formed in double rows (two rows in the figure) from the end and arranged parallel to each other.

  And in this modification, as shown in Drawing 5 (b), it penetrates so that each reinforcing fiber bundle 22 of reinforcing fiber cloth 12 may be sewed into each penetration hole 20 which has arranged in two rows. For example, as shown in the cross-sectional view of FIG. 6, for example, if the reinforcing fiber bundle 22 is inserted from the upper left to the lower right with respect to the through hole 20 on the left in the figure, the lower left for the through hole 20 in the figure The reinforcing fiber bundle 22 is sewn into the metal member 14 by inserting the reinforcing fiber bundle 22 from the upper right. As described above, since the reinforcing fiber bundle has a large restoring force, a large frictional force acts between the reinforcing fiber bundle and the metal member 14, and the frictional force causes the reinforcing fiber bundle 22, that is, the reinforcing fiber fabric 12 to be metal. It is engaged with the member 14. Further, in this embodiment, each reinforcing fiber bundle 22 is inserted such that the reinforcing fiber bundles 22 adjacent to each other are inserted in the opposite direction to the adjacent through holes 20, that is, the reinforcing fiber bundles 22 are sewn alternately. The through hole 20 is inserted. By sewing the reinforcing fiber bundles 22 alternately to the metal member 14 in this manner, the restoring force generated in the adjacent reinforcing fiber bundles 22 becomes larger, and as a result, a large frictional force acts on the metal members 14. As a result, the reinforcing fiber cloth 12 and the metal member 14 firmly engage with each other. Thus, when the reinforcing fiber fabric 12 and the metal member 14 are engaged, they are set in the mold and the resin is injected and solidified in the same manner as in the first embodiment to form a metal-fiber reinforced resin joint member. To get

  7 to 10 are explanatory views showing a second embodiment of the metal-fiber-reinforced resin joint member of the present invention and the method for manufacturing the same. Specifically, FIG. 7 is a perspective view of a metal member 14 and a reinforcing fiber fabric 12 showing a second embodiment of a metal-fiber reinforced resin joint member and a method of manufacturing the same, and FIG. 8 is a metal member 14 of FIG. FIG. 9 is an explanatory view of the coating of the metal member 14 and the reinforcing fiber fabric 12 by the resin member 18 in FIG. 7; and FIG. 10 is the resin member 18 coated with the reinforcing fiber fabric 12. It is a perspective view of a metal-fiber reinforced resin joining member. The respective drawings are schematically shown, and in particular, the resin members 18 in FIGS. 9 and 10 are drawn in an exaggerated manner.

  The schematic configuration of the metal-fiber-reinforced resin bonding member in this embodiment is the same as that of the first embodiment. Further, the reinforcing fiber fabric 12 of the fiber reinforced resin body 10 in this embodiment is also provided with the long and short reinforcing fiber bundles 22 at the end portion engaged with the metal member 14 as in the first embodiment. However, in this embodiment, the reinforcing fiber cloth 12 is formed in the order of short, long, short,... From the end in the width direction. On the other hand, the metal member 14 in this embodiment is also made of a rectangular metal plate as in the first embodiment, but in this embodiment, the plate thickness is somewhat large. Then, in the joining end portion of the fiber reinforced resin body 10 in the metal member 14, a plurality of concave portions 23 are formed in a zigzag, for example, as an engaging portion 16 for engaging the reinforcing fiber cloth 12. . Specifically, among the reinforcing fiber bundles 22 of the reinforcing fiber fabric 12 to be engaged, the recess 23 corresponding to the reinforcing fiber bundle 22 having a smaller projecting dimension is the metal member 14 with which the reinforcing fiber fabric 12 is engaged. The recess 23 corresponding to the reinforcing fiber bundle 22 formed at a position closer to the end and having a large projection dimension is formed at a distant position. The recess 23 may be a hole.

  In this embodiment, an engaging member 24 separate from the metal member 14 is used to engage the reinforcing fiber fabric 12 with the engaging portion 16 having the recess 23 described above. The material of the engagement member 24 can be appropriately selected, but for weight reduction, for example, resin or the like can be applied. Further, it is also possible to use an elastic material such as rubber as the material of the engagement member 24. The engaging member 24 of this embodiment is a plate material similar to the metal member 14, and a plurality of protrusions 25 are provided in a projecting manner on one surface (the lower surface in FIG. 7A) of the plate material. The convex portion 25 is formed at a position facing the concave portion 23 of the metal member 14 and is fitted (loosely fitted) in the concave portion 23, respectively.

  Therefore, the reinforcing fiber bundle 22 corresponding to each of the plurality of concave portions 23 of the metal member 14 constituting the engagement portion 16 is covered, and the respective convex portions 25 are positioned so as to face the concave portions 23 to engage the engagement member 24 is placed on the upper surface of the reinforcing fiber fabric 12, and the engaging members 24 are pressed against the metal member 14 as shown in FIG. 7 (b) so that each protrusion 25 fits into the corresponding recess 23. As a result, as shown in the cross-sectional view of FIG. 8, the reinforcing fiber fabric 12 is sandwiched between the concave portion 23 of the metal member 14 and the convex portion 25 of the engaging member 24, and the reinforcing fiber is engaged with the engaging portion 16 of the metal member 14. The fabric 12 is engaged. At this time, the dimensions of both the recess 23 of the metal member 14 and the projection 25 of the engagement member 24 are set so as not to fit excessively tightly, that is, to fit loosely. As well known, reinforcing fibers exhibit high strength against tension in the fiber direction but are relatively fragile against shearing. When the reinforcing fiber fabric 12 is inserted into the gap between the recess 23 and the protrusion 25, a shearing force acts on the reinforcing fibers constituting the fabric, so that the shearing force does not become too large, that is, the recess 23 and the protrusion Set the dimensions of both so that 25 fits loosely.

  Thus, when the reinforcing fiber fabric 12 is engaged with the engaging portion 16 of the metal member 14, the reinforcing fiber fabric 12 and the metal member 14 are made of gold as shown in FIG. Set in the mold 40. Similar to the first embodiment, this mold 40 is for injecting a resin, and comprises, for example, an upper mold 40 a and a lower mold 40 b, and a seal is formed between the metal member 14 and the mold 40. 41 prevents the resin from leaking. In this state, for example, as in the first embodiment, a resin is injected into the mold 40, and when the injected resin is cured, the mold 40 is released as shown in FIG. 9 (b). As a result, as shown in FIG. 10, the fiber reinforced resin body in a state where at least the engaging portion 16 of the reinforcing fiber fabric 12 and the metal member 14 is covered with the resin member 18 and the resin member 18 is impregnated with the reinforcing fiber fabric 12 As a result, the metal-fiber-reinforced resin bonding member is completed.

  Therefore, in this embodiment, in addition to the effects of the first embodiment described above, the engaging portion 16 is configured by including the concave portion 23 and the convex portion 25 which sandwich the reinforcing fiber fabric 12 by fitting each other. Thus, the reinforcing fiber cloth 12 can be sandwiched and engaged with the metal member 14 only by fitting the recess 23 and the protrusion 25 to each other, so that the engaging portion 16 can be simply configured. The recess 23 may be formed on the engaging member 24 and the protrusion 25 may be formed on the metal member 14.

  FIG. 11 shows a modification of the second embodiment of the metal-fiber-reinforced resin bonding member of the present invention and the method of manufacturing the same. Specifically, FIG. 11 is a perspective view of a metal member 14 and a reinforcing fiber fabric 12 showing a modification of the second embodiment of the metal-fiber-reinforced resin bonding member and the method of manufacturing the same. In this modification, the engagement-side end of the reinforcing fiber fabric 12 with the metal member 14 remains in the form of an elongated square. On the other hand, the metal member 14 and the engagement member 24 in this modification are the same as those in the second embodiment. In this modification, the square end of the reinforcing fiber fabric 12 is placed on the upper surfaces of the plurality of recesses 23 of the metal member 14 constituting the engaging portion 16, and the respective protrusions 25 are aligned so as to face the recesses 23. The engaging member 24 is placed on the upper surface of the reinforcing fiber fabric 12, and the engaging member 24 is pressed against the metal member 14 as shown in FIG. 7 (b) so that each convex portion 25 is fitted into the corresponding concave portion 23. As a result, the reinforcing fiber fabric 12 itself is sandwiched between the concave portion 23 of the metal member 14 and the convex portion 25 of the engaging member 24, and the reinforcing fiber fabric 12 is engaged with the engaging portion 16 of the metal member 14. As described above, when the reinforcing fiber fabric 12 and the metal member 14 are engaged, they are set in the mold and the resin is injected and solidified as in the second embodiment, and the metal-fiber reinforced resin joint member To get In addition, the arrangement position of the said recessed part 23 is not specifically limited, The recessed part 23 may be arrange | positioned so that it may adjoin similarly to embodiment shown in FIG.

  FIGS. 12-15 is explanatory drawing which shows 3rd Embodiment of the metal-fiber reinforced resin joining member of this invention, and its manufacturing method. Specifically, FIG. 12 is a perspective view of a metal member 14 and a reinforcing fiber fabric 12 showing a third embodiment of a metal-fiber reinforced resin joint member and a method of manufacturing the same, and FIG. 13 is a metal member 14 of FIG. FIG. 14 is an explanatory view of the coating by the metal member 14 of FIG. 12 and the resin member 18 of the reinforcing fiber fabric 12 in a state in which the reinforcing fiber fabric 12 is engaged with FIG. It is a perspective view of a coated metal-fiber reinforced resin joint member. The respective drawings are schematically represented, and in particular, the resin members 18 in FIGS. 14 and 15 are drawn in an exaggerated manner.

  The schematic configuration of the metal-fiber-reinforced resin bonding member in this embodiment is the same as that of the first embodiment. In addition, the engagement side end of the fiber reinforced resin body 10 with the metal member 14 of the fiber reinforced resin body 10 in this embodiment has a vertically elongated rectangular shape as in the modification of the second embodiment shown in FIG. It is as it is. On the other hand, in the metal member 14 in this embodiment, a plurality of (six in the figure) engagement protrusions are directed from the end of the metal plate having a width equal to or greater than the width of the reinforcing fiber fabric 12 to the reinforcing fiber fabric 12 side. A projecting portion 21 is provided to form an engaging portion 16 having a clamping structure. Specifically, as clearly shown in FIG. 12 (a), these engagement protrusions 21 are relatively thin, flat, and comb-shaped, and those engagement protrusions 21 are formed of the reinforcing fiber fabric 12 Along the plane direction (joining direction) of, for example, it is inserted as sewn into the fiber.

  In this embodiment, in order to engage the reinforcing fiber fabric 12 with the engaging portion 16 consisting of a plurality of comb-teeth-like engaging protrusions 21, a clamping member 27 separate from the metal member 14 is used. The holding member 27 is bent to hold the reinforcing fiber fabric 12 between the holding member 26 and the holding member 26. Specifically, a band-like holding member 27 bent in a U-shaped cross section as shown in FIG. 12A is used. The material of the sandwiching member 27 can be selected as appropriate, but in this example, it is necessary to be a material that can maintain the bent state, that is, a material that can be plastically deformed.
