To provide a unidirectional carbon fiber woven fabric which has an excellent draping property and an excellent matrix resin-impregnating property is inexpensive, exhibits high strength characteristics, and has a large degree of freedom on designs such as the specification of warps and the Metsuke of the woven fabric, to provide a method for producing the woven fabric, and to provide a concrete structure reinforced with the woven fabric. The unidirectional carbon fiber woven fabric which comprises wefts and warps comprising non-twisted carbon fiber yarns comprising many carbon fibers is, characterized in that the warps are non-twisted doubled warps obtained by doubling plural non-twisted yarns and that the doubled warps and the wefts are bound to each other. The method for producing the unidirectional carbon fiber woven fabric is characterized by doubling the arbitrary number of unwound warps to form the non-twisted doubled warps, weaving the non-twisted doubled warps with wefts to form a preliminary woven fabric, passing the preliminary woven fabric through a heating and pressurizing device to deform the doubled warps into a on-twisted flat shape and simultaneously fuse a thermal-plasticity resin with the doubled warps and fasten the doubled warps. Enforcing the material of concrete structure means to provide the above-mentioned woven materials with fabric reinforced plastic layer.

Description of the invention (1) [Technical Field to which the Invention belongs] The present invention relates to a unidirectional carbon fiber fabric excellent in civil reinforcement applications or carbon fiber reinforced resin applications, and its manufacturing method And reinforced concrete structures. [Known technology] Because carbon fibers have excellent mechanical properties such as specific elastic modulus and specific strength, they are processed into intermediate materials such as fabrics, fabric pre-pregs, or unidirectional pre-crush bodies to form them. It can be used as a material for repairing and reinforcing carbon fiber reinforced resin (CFRP) contained in matrix resin or concrete structures. In order to reduce the lamination operation steps for the above purpose, when making large grid fabrics with thick stone anti-fiber threads, the restraint is strengthened by the interlacing of warp and weft threads, and the fabric has drapability (softness) ) Or impregnation of the matrix resin becomes lacking. In the past, unidirectional carbon fiber fabrics with large lattices were manufactured by making the spacing of the weaving yarns smaller than the width of the carbon fiber warp threads and increasing the fabric density. However, the gap between the warp threads of the obtained fabric was too dense, which made the matrix Impregnation of the resin becomes insufficient. Therefore, even if such a fabric is used for molding, it is not possible to obtain a uniform shaped product (pre-collapsed body, etc.) or a laminate, which may cause unevenness such as voids and stress concentration. Problem. In addition, the commercially available carbon fiber yarn is a specification with a certain fineness and width, and because the sizing agent is used to maintain the shape, it is difficult to use this as a warp of unidirectional carbon fiber fabric.

The warp yarn used in the present invention is generally obtained by combining 2 to 5 untwisted carbon fiber yarns, and the fineness of the obtained yarn is preferably 10,000 to 40,000 denier. The plurality of carbon fiber lines forming a warp line can be separated from each other or can form a line without boundaries. For example, the general carbon fiber thread is obtained in a state where the shape is maintained by a sizing agent, but when only a plurality of these threads are combined, a mutually independent fusion line can be obtained. On the other hand, when this joint is heated to a temperature above the melting point of the sizing agent, the fibers constituting each strand will be untied, and the boundary with the other adjacent threads will disappear, and a strand will be formed when it is cooled. When the threads and threads constituting a warp are separated from each other independently, the matrix resin has the advantage of being easily impregnated through the space between the threads. On the other hand, when a line and a line become a borderless line with each other, there is an advantage that it cannot be easily unlocked. The carbon fiber of the warp yarn generally does not contain a hardening agent, and an epoxy resin sizing agent of about 5% to 25% by mass is attached. When the sizing agent is less than 0.05% by mass, there will be a lot of warp threads in the weaving step. Fluffing makes it difficult to maintain the flat shape of the warp after weaving. On the other hand, an adhesive exceeding 2.5% by mass may impede the impregnation of the matrix resin with the fabric and may reduce the physical properties of the molded product, which is not desirable.

Description of the invention (6) Melts below the temperature, of course this melting point is used Below the melting point of the weft, for example, nylon resin, polyester resin, and polyethylene resin are used. (Please read the precautions on the back before filling out this page.) In the method for manufacturing unidirectional carbon fiber fabric of the present invention, The fiber yarns are blocked to form a plurality of untwisted warp yarns. Because the arbitrary yarns are yarned together, the fineness, width, pitch / width ratio of the warp yarns obtained, and the setting of the grid of the fabric become Easy, high degree of freedom in fabric design. Figure 2 It means to make every 2 flat carbon fiber lines 丨 (indicate a cross-sectional view: passing through a pair of clents 8 and 8 to form one warp line. When flat carbon fiber lines are to be joined Although it is possible to simply combine the flat surfaces and laminate them on top and bottom, it is better to combine them by tilting and staggering them as shown in Figure 2. This is because the resulting convergence line is close to a line. The state is not easy to untie. Even when a carbon fiber thread of a certain fineness is made into, for example, two strands, as described above, the strands are not limited to only two times, and can be made. It can be made into various rafters, so that the design freedom is higher. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs in the manufacturing method of the present invention, weaving warp threads and weft threads containing thermoplastic resin are passed The two wires are fixed by a heating and pressing device such as a hot roller. This heating temperature must be the temperature at which the thermoplastic resin is melted, and if the warp yarn contains a sizing agent, the viscosity of the sizing agent decreases, and the carbon fiber threads of the yarn become a whole, and the warp yarn is easy to become flat. The temperature of the shape is suitable, generally 90 to 12 (rc, preferably 100 to 0 C. In addition, after the warp and weft threads are woven, the overheating and pressurizing device changes the warp when it is flattened. The width of the line is preferably 3 to 16 centimeters.

Description of the invention (7) It is preferably 0.1 to 0.6 cm. In the unidirectional carbon fiber fabric of the present invention, the ratio of the width of the warp yarns relative to the distance between the warp yarns is preferably chuanchuan to 3. The fabric grid is preferably 200 to 1,000 g / m 2, the fiber density is preferably 0 8 to 2 g / cm 3, and the fabric thickness is preferably in the range of 0.1 to 0.05 cm. Here, The fiber density of a fabric is defined by the following formula: The fiber density of a fabric (g / cm3) = [fabric (G / v)] / [fabric thickness (mm)] Also, the value of “fabric grid (g / m2)” and fabric thickness (mm) are measured based on JIS r76〇2, which is the best embodiment of the present invention. The unidirectional carbon fiber fabric has the same fiber pitch and width, so the fiber density of the fabric is relatively large. Compared with the fiber density of the general unidirectional carbon fiber fabric, 0.8g / cm3, It can be set to 0 to 2 2 g / cm3. When fabrics with a fiber quality and degree within the above range are used, they can be formed even by simple forming methods such as hand-laying or vacuum bag forming.

Therefore, a plain weave is preferable from the viewpoint of I-state feminine sex. 'The fabric of the invention, Flat warp yarns are woven with a very thick density, which is easy to be cut and deformed because the crimp of the yarn is small, that is, this I paper size applies the Chinese National Standard (CNS) A4 rules ¥ each (210 X 297 public love)--312997 -------------- A ___ w -------- order --------- line (please read the note on the back first?
