Title:
METHOD FOR MANUFACTURING FIBER REINFORCED RESIN MOLDED BODY AND METHOD FOR MANUFACTURING UNIDIRECTIONAL FIBER REINFORCED MEMBER
Document Type and Number:
WIPO Patent Application WO/2018/038205
Kind Code:
A1
Abstract:
A method for manufacturing a fiber reinforced resin molded body comprises a UD tape manufacturing step and an extrusion molding step. In the UD tape manufacturing step, a UD tape is manufactured. In the extrusion molding step, the UD tape manufactured in the UD tape manufacturing step is introduced into an extrusion die together with melted thermoplastic resin from an extrusion device. In the extrusion die, a cross-sectional shape of the thermoplastic resin is molded into a prescribed cross-sectional shape, while the UD tape and the thermoplastic resin merge with each other. By means of a resin pressure of the thermoplastic resin that has merged with the UD tape, the UD tape is joined to a prescribed region of the thermoplastic resin molded to have the prescribed cross-sectional shape. The thermoplastic resin molded to have the prescribed cross-sectional shape is ejected from the die together with the UD tape that has been joined to the prescribed region, thereby extrusion-molding a fiber reinforced resin molded body.
