題がある。However, in the above method, there are problems in that it is difficult to uniformly disperse the resin, it takes a lot of man-hours, it is difficult to make the resin into fine wires and long fibers, the wires are easily broken, and the workability is poor.
そこで、この発明は、上記の問題点を解決するプリプレ

溶剤を使用しないので、作業環境がよい。[Function] In this method, the resin matrix is applied as a powder to the reinforcing fibers, so that the resin is uniformly dispersed in each reinforcing fiber. Furthermore, since the amount of coating can be adjusted, the resin content of FRP can be adjusted as desired. Furthermore, since uniform tension is applied to the reinforcing fibers, the fibers are well aligned and there is little risk of wire breakage. Also,
Since no solvent is used, the working environment is good.
