Title: NOTCHED PREPREG AND METHOD FOR PRODUCING NOTCHED PREPREG
Abstract:
Provided is an intermediate base material (notched prepreg) which has exceptional surface quality and mechanical properties when solidified and with which it is possible to obtain a fiber-reinforced plastic having excellent three-dimensional shape conformance properties. This notched prepreg has, in a prepreg that includes a resin and reinforcing fibers oriented in one direction, notches substantially parallel to the orientation direction of the reinforcing fibers (the notches substantially parallel to the orientation direction of the reinforcing fibers are referred to as parallel notches) and notches that cut across the reinforcing fibers (the notches that cut across the reinforcing fibers are referred to as transverse notches).
