Abstract

The invention provides a method of manufacturing a fiber-reinforced composite material, and can suppress reduction of quality of the fiber-reinforced composite material caused by air bubbles mixed inresin during molding. The method of manufacturing the fiber-reinforced composite material includes: a storage process of storing a fiber-reinforced sheet (11) in a cavity (23) of a mold (20); and a molding process of injecting the resin (12) into the cavity (23) of the mold (20), impregnating the fiber-reinforced sheet (11) with the resin (12), and curing the resin (12). In the molding, after fineair bubbles (29) contained in the resin (12) are placed at a predetermined position of the cavity (23), the resin (12) is cured.

Description

technical field [0001] The present invention relates to a method for producing a fiber-reinforced composite material, and more particularly to a fiber-reinforced composite material in which the positions and sizes of air bubbles contained in the resin are properly controlled when a resin is impregnated into a reinforcing fiber sheet inside a molding die (mold) and cured. The method of manufacture of the material. Background technique [0002] In recent years, resin transfer molding (RTM) methods, reaction injection molding (RIM) methods, and the like have been used as methods for producing fiber-reinforced composite materials. In these methods, a laminated body in which a plurality of reinforcing fiber sheets are laminated is placed in a mold, and after the mold is closed, uncured resin is injected to impregnate the laminated body and then cured. According to this method, since a laminated body composed of a dry base material not impregnated with a resin is shaped, a molded...
