Description

【０００７】
【課題を解決するための手段】
上記課題を解決するために、本発明のＦＲＰ構造体は、基本的には中空体と、該中空体の周囲に配置されたＦＲＰ層とを有するＦＲＰ構造体であって、前記ＦＲＰ層が、強化繊維基材に樹脂が実質的に同時に含浸され実質的に同時に硬化される一発成形により成形されたものからなる。 0007
[Means for solving problems]
In order to solve the above problems, the FRP structure of the present invention is basically an FRP structure having a hollow body and an FRP layer arranged around the hollow body, and the FRP layer is a structure. It is formed by one-shot molding in which a reinforcing fiber base material is impregnated with resin substantially at the same time and cured substantially at the same time.

本発明に係るＦＲＰ構造体は、中空体と、該中空体の周囲に配置されたＦＲＰ層とを有するＦＲＰ構造体であって、前記中空体の周囲に樹脂拡散手段が設けられており、少なくとも前記ＦＲＰ層の強化繊維基材と前記周囲に樹脂拡散手段が設けられた中空体が樹脂により一体化されていることを特徴とするものからなる。この樹脂拡散手段は、たとえば、網状体などの媒体、あるいは、中空体の表面に設けられた溝から構成できる。 The FRP structure according to the present invention is an FRP structure having a hollow body and an FRP layer arranged around the hollow body , and a resin diffusion means is provided around the hollow body, and at least It is characterized in that the reinforcing fiber base material of the FRP layer and the hollow body provided with the resin diffusion means around the FRP layer are integrated with the resin. The resin diffusion means can be composed of, for example, a medium such as a net-like body or a groove provided on the surface of the hollow body.
