Method for producing fiber-reinforced plastic substrate, and fiber-reinforced plastic substrate and integrated molding thereof

Abstract

A method is described for producing a fiber-reinforced plastic substrate that simultaneously satisfies three points of joinability, mechanical characteristics, and productivity, the method including the following components [A], [B], and [C], wherein at least the following drawing step, first impregnating step, second impregnating step, and take-up step are continuously and sequentially performed while the component [A] is caused to run: [A] a reinforcing fiber [B] a thermoplastic resin [C] a thermosetting resin 2<drawing step> step of drawing a continuous reinforcing fiber sheet containing the component [A]; <first impregnating step> step of impregnating either the component [B] or the component [C] from one surface of the continuous reinforcing fiber sheet to obtain a fiber-reinforced plastic intermediate in which either the component [B] or the component [C] is disposed on a first surface; <second impregnating step> step of impregnating the other of the component [B] or the component [C] from a second surface opposite to the first surface to obtain a fiber-reinforced plastic substrate; and <take-up step> step of taking up the fiber-reinforced plastic substrate.
