せた後、型から取り出す。(First Embodiment) Next, the method for manufacturing a fiber-reinforced plastic component of the present invention is applied to the manufacture of a bicycle front hawk.
The first embodiment will be described. (1) As shown in FIG. 1A, a front fork core material 1 is made of a foam material (for example, polyurethane foam). (2) As shown in FIG. 1 (b), reinforcing fibers are woven so as to cross each other to form one continuous hollow braid 2. (3) As shown in FIG. 1 (c), the front fork core material 1 is inserted into the assembly 2 through one end opening of the same assembly 2, and the U-shaped portion of the front fork core material 1 ( Left and right front hawk legs 1a, 1b)
Are coated with the same braid 2. This braid 2 has a thread angle of 15
Since it is less than or equal to ° and easily spreads in the direction orthogonal to the longitudinal direction, the front fork foot portions 1a and 1b can be easily inserted. A yarn having a thread angle of 15 ° or more is difficult to spread in the direction orthogonal to the longitudinal direction.

率とを比較している。In the fiber reinforced resin product, when the braid 2 is cut (cut), stress concentrates on the cut product, and the rigidity tends to be insufficient. Therefore, when manufacturing a trifurcated to quadrifurcated joint part or other similar parts (for example, bicycle front hawk or lug), one continuous hollow assembly 2
To use. FIG. 5 shows the results of the three-point bending test of a sample of 10 layers of carbon fiber (CF) fabric (plain weave cloth), in which the bending strength and bending elastic modulus in the 0 ° / 90 ° direction are compared.

From FIGS. 5 and 6, it can be seen that the carbon fiber reinforced plastic (CFRP) product is a material having a strong anisotropy in which the rigidity value largely changes depending on the fiber orientation. That is,
The smaller the yarn angle of the braid, the higher the rigidity value.

This numerical value is a rigidity value of CF cloth 10 ply or more. That is, when the same rigidity value is required, the use of one continuous hollow braid reduces the amount of the base material, and achieves both weight reduction and cost reduction.

Get better. FIG. 8 shows the calculated thread angle of the braid 2 of the front bicycle hawk.
