があった。However, as can be seen from the table, in the case of the above conventional method, the tension of the reinforcing fiber acts on the mandrel, and in general, when the resin is cured while being rotated once, excessive tension is applied sequentially, especially at the beginning of winding on the mandrel side. KIJ), as a result, the reinforcing fiber density on the mandrel side becomes large. As a result, the fibers were exposed and the surface became rough, resulting in poor appearance, and uneven fiber density led to problems with strength and durability.

This is a method of manufacturing an FRP strip by integrally molding t% mold.

By the above operation, it is possible to prevent excessive tension from being generated in the fibers arranged on the mandrel side, so as in the case of Example 1, it is possible to prevent the fibers from being biased toward the mandrel side.
A product with good physical properties and appearance can be obtained.

That is, at the beginning of winding, the fiber content is reduced and the tension is set low, and at the end of the winding, the fiber content is increased and the tension is increased. By doing so, the effects of Example 1.2 can be synergistically exhibited, and a high quality product with particularly excellent fatigue resistance can be obtained.

l The reinforcing fibers are impregnated with a resin containing an internal mold release agent such as rough-in, and after that, the resin is replaced and impregnated with one that does not contain a mold release agent, and then rolled up.
□This way, the mold release agent can be supplied only to the areas where it is needed, which saves on mold release agent, and the mold release agent does not spread throughout the resin, making it easier to use the mold release agent.
It is possible to minimize the decrease in strength due to the presence of the type Il agent.

り。It should be noted that the present invention is not limited to these examples, but can be carried out by variously changing the supply conditions of reinforcing fibers or resin, contrary to the gist of the present invention. For example, the tension, content, etc. of the reinforcing fibers may be changed only partially during the winding process, or the entire winding process may be the same.

果がある。As described above, the present invention changes the supply conditions of the reinforcing fibers or resin during the winding of the reinforcing fibers. It is possible to prevent defects such as the unevenness of fibers 9, which has been observed, and to improve durability and surface appearance. Furthermore, according to the present invention, it is possible to arbitrarily change the fiber density in the thickness direction of the strip to be molded, so it has great effects such as being able to obtain a variety of strips that meet design requirements. .
