ABSTRACT:
According to the present invention, a porous FRP sheet can be easily manufactured without need for the punching or drilling process which is required in conventional prior methods for manufacturing an FRP sheet. The FRP sheet manufactured by the present method has superior reinforcing characteristics, since the reinforcing fibers composing the FRP sheet are not cut but are retained in continuous condition.
