Title:
PROCESS AND APPARATUS FOR PRODUCING FIBER-REINFORCED PLASTIC
Document Type and Number:
WIPO Patent Application WO/2011/043253
Kind Code:
A1
Abstract:
Disclosed are a process and an apparatus for producing a fiber-reinforced plastic by disposing a reinforcing fiber base in the cavity formed by an upper mold and a lower mold, closing the cavity, thereafter injecting and infiltrating a matrix resin into the reinforcing fiber base, and curing the resin, the process and apparatus being characterized in that the resin is injected and infiltrated into the reinforcing fiber base while keeping the height of the cavity larger than the thickness of a given molded article. The process and the apparatus are further characterized in that after the infiltration, the resin which has been excessively injected and infiltrated into the reinforcing fiber base is sucked and removed and, simultaneously therewith, at least one of the upper and lower molds is pressed against the other to thereby regulate the height of the cavity so that the thickness of the reinforcing fiber base becomes equal to the thickness of the given molded article, and that the resin is cured while keeping the state of the cavity. Thus, a large-sized and thick-walled molded article which has a high Vf and can sufficiently show high-strength and high-elasticity characteristics attributable to the reinforcing fibers can be produced at low cost.
