Title:
COMPOSITE MATERIAL OF FIBER-REINFORCED RESIN AND WEIGHT-SAVING CORE, AND METHOD AND APPARATUS FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2013/011884
Kind Code:
A1
Abstract:
In cases where a composite material, which is provided with a fiber-reinforced resin and a weight-saving core adjacent to the fiber-reinforced resin, is produced, the composite material is produced with high molding accuracy at high rate without increasing the weight of the composite material, while preventing the resin from flowing into pores in the surface of the weight-saving core. In order to produce a composite material which is provided with a weight-saving core and a fiber-reinforced resin that is adjacent to at least a part of the surface of the weight-saving core, the following steps are carried out: a step (100) wherein a core, which is provided with a part having a shape that is substantially the same as a part of a weight-saving core adjacent to a fiber-reinforced resin, and a fiber base to be arranged adjacent to the core are disposed within a mold; a step (110) wherein a resin material is poured into the mold, so that the fiber base is impregnated with the resin material; a step (120) wherein the resin material is cured; a step (130) wherein the core and the cured resin containing the fiber base are taken out of the mold; and a step (150) wherein the cured resin containing the fiber base and the weight-saving core are integrated with each other.
