れる役割を果たす。In the above, the forces acting on the composite fastener 7 and the composite parts 11 and 12 act as shown in FIG. That is, the shearing force 2 acting on the component 11 is converted into the tension 4 of the fiber 1 via the component 11 and the bonding surface 3 of the fiber 1 of the composite fastener 7. Next, this tension 4 propagates in the fiber 1 and is transmitted to the bonding portion between the fastener 7 and the component 12, and finally, the tension 4 of the fiber 1 passes through the bonding surface 5 between the component 12 and the fiber 1. , The shear force 6 of the component 12 is converted and transmitted. Here, the twist given to the fibers 1 forming the composite material fastener 7 plays a role in smoothly transmitting the tension 4 acting on the fibers 1 from the portion bonded to the component 11 to the portion bonded to the component 12.
