PURPOSE:To obtain a stretching member having large stretching capacity by a method wherein the portion, which is not impregnated with resin, is provided at both ends of each fiber reinforced resin composite body and a plurality of said fiber reinforced resin composite bodies are bundled to form an integral body by impregnating the portions, each of which is not impregnated with resin, with resin and hardening the resin. CONSTITUTION:As the continuous long fiber, carbon fiber or aramid fiber is favorably used from the viewpoint of the physical properties such as tensile strength and the like. As the matrix of the fiber reinforced resin composite material, thermosetting resin such as epoxy resin, unsaturated polyester resin or the like is used. And, a stretching member 1 made of fiber reinforced resin composite bodies is produced by bundling a plurality of stretching members 2 made of fiber reinforced resin composite bodies and hardening the portions, each of which contains no resin, by means of resin. The integral fixation of both the ends of the stretching member 1 is important or the shape of each portion, which is formed by hardening the portion containing no resin by means of resin, is formed so as to be larger than the portion, which is formed by bundling a plurality of the stretching members 2 made of fiber reinforced resin composite bodies. Accordingly, the arbitrary shape can be obtained. The stretching and anchoring work is easily done by utilizing the above-mentioned larger portion. |
