Abstract
The present invention relates to a method for molding fiber-reinforced plastic that is characterized: in comprising a process () for accommodating flowable grains comprising multiple particles in a flexible bag to form a core, a process () for interposing the core between fabric configured from fibers and placing the fabric and core inside a molding die, and a process () for injecting a resin into the molding die into which the fabric and core have been placed and curing; and in that, when performing the curing in process (), a portion of one of the outer surfaces of the core is pressed and deformed by a pressing means to increase the internal pressure inside the core. The present invention provides a method for manufacturing fiber-reinforced plastics of excellent external appearance in which there are no defects such as wrinkles in the outer surface during forming using a core.
