Patent ID: 8647095

Claim:
A resin transfer molding (RTM) device comprising: a mold having an interior comprising a resin reservoir, the mold holding within said interior a molded body made of a reinforcement fiber material and holding at each of opposite surfaces of the molded body a hollow chain curing polymer (CCP) accommodating layer having a thickness of approximately 0.5 mm to 20 mm, a heat insulating member positioned between each CCP accommodating layer and the mold, and a separating element positioned between the molded body and each CCP accommodating layer; a resin injection line injecting CCP resin into the resin reservoir and into the remaining interior of the mold to impregnate the molded body and to fill each CCP accommodating layer; a radiation source initiating curing of said injected resin; and a suction line decreasing pressure of the interior of the mold, wherein CCP resin curing in the resin reservoir and in each CCP accommodating layer generates heat maintaining conditions allowing for a chain reaction of the injected resin to proceed uninterrupted so as to form a fiber-reinforced plastic (FRP) molded body, and wherein the FRP molded body has a fiber volume content (Vf) limit value depending on curing characteristics of the CCP resin and on heat dissipation characteristics of the CCP resin to outside of the mold.
