力特性を発揮することができなかった。(Problem to be Solved by the Invention) The above conventional method is effective as a method for end-stopping fiber-reinforced plastic wire rods and polyoxymethylene wire rods using glass fibers or aromatic aramid fibers;
When fiber-reinforced plastic wires made of ultra-high molecular weight polyethylene fibers with a molecular weight of 500,000 or more and a high modulus of elasticity are end-stopped using these methods, the tensile strength properties of the ultra-high molecular weight polyethylene fibers are fully exhibited. There was a problem that it was not done. In other words, when the end of the wire is formed into a loop, the wire undergoes crushing deformation, resulting in a decrease in strength, and the wire becomes hollow at the caulked portion, making it impossible to utilize the original strength of the wire. Also, the method of inserting it into a socket or fitting a metal pipe and hardening it with resin is
The adhesion between the wire and the resin was weak, and the end of the wire could be easily pulled out of the resin-embedded part under relatively low stress, making it impossible to exhibit the high tensile strength properties of the wire.

By crimping the ring, the bonding area between the wire and the embedding resin increases, the embedding resin firmly adheres to the end of the wire, and tensile stress below the tensile strength of the wire will cause it to break through. It disappears. In particular, when the embedding resin liquid is applied to the flattened part in advance, it is inserted into a cylindrical or rectangular parallelepiped mold with a taper, so-called a socket, and the embedding resin is filled and solidified into this socket. Adhesion is even stronger.

合の性能が著しく向上する。(Effect of the invention) This invention is a simple method of flattening the end of a fiber-reinforced plastic wire containing ultra-high molecular weight polyethylene fiber, fitting a metal ring to the armpit, and embedding and fixing it in resin. Compared to the conventional method, the contact area with the embedding and fixing resin is significantly increased, improving adhesive strength and strong retention of the wire, eliminating the conventional process of slip-through and complicated work, and improving ultra-high molecular weight The excellent tensile strength of fiber-reinforced plastic wire containing polyethylene fibers can be fully utilized.
When used as a tension member for optical fiber cables, a tensile strength material for wire ropes, wire cables, etc., the performance is significantly improved.
