PURPOSE: To contrive to improve connection effect and durability, to relieve the discontinuity in rigidity and the like by a method wherein fibrous bodies are exposed by removing cured resin at the end of each of FRP wiry bodies and, after being impregnated with uncured resin, braided in together so as to be connected with each other.
CONSTITUTION: When a plurality of FRP wiry bodies 10 are to be connected with each other, firstly the cured resin 14 at the end of each of the FRP wiry bodies 10 is removed through chemical decomposition so as to expose fibrous bodies 16. Next, the exposed fibrous bodies 15 are impregnated with uncured resin 18, which is the same kind as the resin 14, and then braided in together so as to be connected with each other. Or, after the fibrous bodies 16 are braided in together so as to be connected with each other, uncured resin 18, which is the same kind as the resin 14, is infiltrated in the fibrous bodies. In succession, the uncured resin 18 is cured by heating. Thus, the tensile strength represented by the fibrous body 16 is utilized and the connection effect is improved. Further, the characteristics of the fibrous bodies 16 are held as those of other FRP wiry bodies so as to relieve the discontinuity in rigidity and, at the same time, to improve the durability of the FRP wiry bodies.
