Fiber-Reinforced Composite Member Forming Device

Abstract

Provided is a fiber-reinforced composite member forming device provided with: a pair of forming die parts 2, 3 which approach and separate from each other to sandwich, in a clamped state, a prepreg obtained by impregnating a resin into a plurality of laminated woven fabrics; and a heat source 4 for heating the prepreg resin via the pair of forming die parts 2, 3. Each of the pair of forming die parts 2, 3 is equipped with base dies 21, 33 and design dies 25, 35 that are detachably mounted on the base dies 21, 33 and come into contact with the pregpreg. The design dies 25, 35 in the pair of forming dies parts 2, 3 are made from a metal having a lower coefficient of thermal expansion than the base dies 21, 33, and by adopting a split structure in the forming die parts, it is possible to keepthe effects expansion of the forming die parts due to heating has on the fiber-reinforced composite member during heating when forming low, after achieving a reduction in the burden on workers involved in replacing the forming die parts.

Description

technical field [0001] The present disclosure relates to a molding device for a fiber-reinforced composite member for molding a fiber-reinforced composite member obtained by laminating a plurality of prepregs obtained by impregnating a fiber woven fabric with a thermosetting resin or a thermoplastic resin as a matrix. Got it. Background technique [0002] When molding a thermoplastic CFRP member (fiber-reinforced composite member) by laminating a plurality of prepregs obtained by impregnating the above-mentioned fiber fabric, such as carbon fiber fabric, with a thermoplastic resin as a matrix, a molding method using an autoclave has been established. However, in recent years, as a molding method replacing the molding method using an autoclave, a mold hot press molding method using a molding device is being constructed. [0003] As a molding apparatus used in this mold hot press molding method, there is an apparatus described in Patent Document 1, for example. The molding d...

Problems solved by technology

In this way, when the molding die part is an integral body of tool steel, if the replacement frequency of the molding die part is low, the burden on the operator can be small. However, when molding a thermoplastic CFRP member with many changes, the weight The replacement frequency of the enlarged molding die part becomes higher, and accordingly, the burden on the operator becomes larger
