Method for producing reinforcing fiber substrate, method for producing reinforcing fiber preform and method for producing fiber reinforced composite material body

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method of a reinforced fiber substrate not only excellent in yield of a reinforced fiber bundle, but also excellent in handleability (especially shape stability of the reinforced fiber substrate) during transportation or shapability in a preform size enlargement process, and a manufacturing method of a reinforced fiber preform and a fiber reinforced composite material molded body, good in impregnation property of a matrix resin, and excellent in physical properties such as impact resistance, especially compression strength:CAI after adding impact.;SOLUTION: There is provided a manufacturing method of a reinforced fiber substrate, having a network resin material sheet arrangement process for arranging a network resin material sheet on a table having temporarily fixing means, a reinforced fiber bundle layer formation process for repeating arrangement from a reinforced fiber bundle mounting head and mount of at least one reinforced fiber bundle on the network resin material sheet, and an adhesion process for adhering the network resin material sheet and the reinforced fiber bundle at least partially.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2019,JPO&INPIT
