Title:
MANUFACTURING METHOD FOR FIBER-REINFORCED PLASTIC AND FIBER-REINFORCED PLASTIC
Document Type and Number:
WIPO Patent Application WO/2017/159567
Kind Code:
A1
Abstract:
This manufacturing method for a fiber-reinforced plastic includes: a lamination step for obtaining a pre-preg laminated body by laminating a plurality of sheets of a pre-preg group containing a notched pre-preg, wherein the notched pre-preg is made by inserting, in a pre-preg including a reinforced fiber arranged in one direction and a resin, a plurality of notches dividing the reinforced fiber in at least a portion of an area of the pre-preg; a shape step for obtaining an approximately mold-shaped pre-form by placing the pre-preg laminated body on an upper surface of a mold including an upper surface and a side surface or a lower surface of a mold including a lower surface and a side surface, and bending and shaping along the side surface; and a solidification step for placing the pre-form in a mold differing from the mold used in the shape step for solidifying. Provided is the manufacturing method for the fiber-reinforced plastic exhibiting excellent surface quality and mechanical characteristics by hot forming.
