工程が行われる。The present invention will be described in detail below with reference to the embodiments shown in the drawings. FIG. 1A shows a rod-shaped body 1. The rod-shaped body 1 uses an ultraviolet curable resin 2 as an example of a photocurable resin. As the ultraviolet curable resin, for example, a polyester resin, an epoxy resin or the like mixed with an ultraviolet curable agent is used. First, a step of irradiating the surface of a converging body 4 formed by converging roving fibers 3 such as carbon fibers, glass fibers, aramid fibers impregnated with the ultraviolet curable resin 2 with ultraviolet rays to semi-cure the converging body 4 is first performed. Be done. After this step, a step of covering the surface of the converging body 4 with the light shielding film 5 is performed.

硬化する。Next, as shown in FIG. 1C, the rod-shaped body 1 on which the tape 7 is wound is pressed against the mold base 7 to bend the portion around which the tape 7 is wound. At this time, the rod-shaped body 1 tends to become flat at the bent portion, but is restrained by the tape 7 and the bent portion remains a perfect circle as shown in FIG. 1D. Since the tape 7 is wrapped and spirally wound so that the overlapping of the tapes 7 does not come off even if the converging body 4 is bent, even if the converging body 4 is bent, the bent portion is completely bent. Since the tape is covered with the tape 7, the bent portion of the converging body 4 is completely prevented from becoming flat. After that, the tape 7 is removed from the converging body 4, the light shielding film 5 is further removed, and the converging body 4 is irradiated with ultraviolet rays. By performing this step, the converging body 4 is cured.

繊維強化構造用棒状体の加工方法と異なるのである。FIG. 2 shows another embodiment. In this embodiment, there is no step of covering the surface of the converging body with a light-shielding film, and the tape 7 is wound in a spiral shape so as to wrap around the entire length of the converging body. That is, the step of covering the semi-cured converging body 4 with the light shielding film 5 and the step of peeling off the light shielding film 5 after further bending processing are not included, and the fiber reinforced of the previous embodiment shown in FIG. This is different from the processing method of the structural rod-shaped body.
