Abstract
Provided is a method for manufacturing a fiber-reinforced plastic molded body by which, when a molded article having a hollow part is being molded using a molding mold, it is possible to deform the peripheral surface area of a core by increasing the pressure inside the core without using pressurized gas or pressurized fluid. A group of particles and the like including a particle group and a core block is accommodated in a flexible bag to form a core. The particle group is composed of multiple rigid particles. The core is arranged inside a prepreg containing a resin and fibers, and the prepreg including the core is arranged inside a molding mold and is molded by applying pressure.
Claims11
A method for manufacturing a fiber-reinforced plastic molded body, the method comprising:
- accommodating a particle group including rigid particles and a core block in a flexible bag to obtain a deformable core;
- disposing the deformable core and a prepreg containing a resin and fibers inside a molding die such that the deformable core is disposed inside the prepreg,
- subsequently compression molding the prepreg, and
- pressing a part of an outer surface of the core at the time of the compression molding so as to provide fluidity to the particle group for deforming the deformable core.
