FIBER-REINFORCED COMPOSITE FORMING METHOD AND FIBER-REINFORCED COMPOSITE FORMING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/191967
Kind Code:
A1
Abstract:
Provided is a fiber-reinforced composite forming method comprising: an arrangement step (S101) for arranging, in a forming die (20), a fiber base material in which a core part having a long foaming body having elasticity and a cover member sealing the foaming body is accommodated in a hollow part; a sealing step (S102) for sealing the fiber base material in the forming die to form a sealed space; an injection step (S103) for suctioning air in the sealed space formed by the sealing step, reducing the pressure of the sealed space, and injecting a thermosetting resin material into the fiber base material; a curing step (S104) for heating and curing the thermosetting resin material injected into fiber base material in the injection step; a detachment step (S105) for detaching, from the forming die, a fiber-reinforced composite including the thermosetting resin material cured in the curing step and the fiber base material; and a removal step (S106) for reducing the pressure of an inner space (IS) sealed by the cover member, contracting the foaming body, and removing the core part accommodated in the hollow part of the fiber-reinforced composite.
