Title:
METHOD FOR MOLDING FIBER-REINFORCED PLASTIC, AND MOLDING DEVICE FOR SAME
Document Type and Number:
WIPO Patent Application WO/2013/187399
Kind Code:
A1
Abstract:
A method for molding fiber-reinforced plastic. A core is formed in a desired shape by accommodating, in a flexible bag, a particle group containing a plurality of particles. The core is placed inside a prepreg containing resin and fibers, and the prepreg, in which the core is housed, is placed in a molding die and compression molded. When doing so, the particle group contains first and second particles (a, b) that satisfy the equation (1). (1) 1.1≤(Da/Db)≤2.0 In the equation, Da is the particle diameter of the particles (a), and Db is the particle diameter of the particles (b). When using a molding die to mold a molded article having a cavity, the abovementioned molding method enables an increase in the internal pressure of the core in order to change the peripheral surface area of the core, without using a pressurized gas and/or a pressurized liquid.
