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.

"Tongwei unidirectional carbon fiber fabric" refers to a line arranged in a certain direction (such as the longitudinal direction) to reinforce the concrete structure. Carbon fiber yarns of objects such as objects are woven with yarns arranged in the other direction (horizontal direction) to maintain the shape of the carbon fiber yarns arranged in the longitudinal direction. Therefore, weft threads are also called auxiliary threads. If the thread is not untied, it can be composed of any fiber.

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.

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.

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. CFRP with a large fiber volume content, that is, good mechanical properties 〇 The unidirectional carbon fiber fabric of the present invention is a fabric composed of interlaced warp threads and weft threads composed of a plurality of carbon fiber threads, and the textile structure is not special It is limited to rhombic or satin weaves, etc. However, compared with ordinary fabrics, the interval between the wefts of the fabric of the present invention is larger, and the lattice is easily shifted. 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?
