Title:
METHOD AND APPARATUS FOR PRODUCING FIBER-REINFORCED RESIN MATERIAL
Document Type and Number:
Japanese Patent JP2017165048
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a method and an apparatus for producing a fiber-reinforced resin material capable of manufacturing a fiber-reinforced resin material which can uniformly disperse a reinforced fiber in a thermoplastic resin while keeping a fiber length of the reinforced fiber, and has more excellent mechanical physical properties.SOLUTION: A method and an apparatus for producing a fiber-reinforced resin material includes: a first step of melting a thermoplastic resin R, and mixing the molten thermoplastic resin with a reinforced fiber F to manufacture a mixed material; a second step of storing the mixed material in a seal space 3, supplying a supercritical fluid into the seal space 3, and impregnating inside of the reinforced fiber F forming the mixed material with the molten thermoplastic resin R to produce a reinforced fiber impregnation material containing the supercritical fluid; and a third step of taking out the reinforced fiber impregnation material from the seal space 3, placing the reinforced fiber impregnation material under decompressed atmosphere, and foaming the supercritical fluid to produce a fiber-reinforced resin material.SELECTED DRAWING: Figure 1
