LAMINATED SUBSTRATE AND FIBER-REINFORCED PLASTIC

摘要

PROBLEM TO BE SOLVED: To provide a laminated substrate formed by laminating notched prepreg substrate materials having a good flowability, form-following property and wide stable process window and exhibiting an excellent dynamic physical characteristic, quality stability and appearance grace on molding as an FRP. SOLUTION: This laminated substrate has a part laminated by at least a multiple number of notched prepreg substrate materials having a multiple number of notches having a limited length in crossing direction of reinforcing fibers arranged in one direction. the reinforcing fibers existing in the notched prepreg substrate materials are cut in 10 to 100 mm length by the notches. In the optional adjacent 2 layers of the notched prepreg substrate materials, positions where the region of 80% of the central part of the notches of one of the notched prepreg substrate materials and the notches of another notched prepreg substrate material cross are≤1 position per 100 cm2.
