PRODUCTION OF FIBER REINFORCED PLASTIC MOLDED FORM

摘要

PURPOSE:To sufficiently impregnate a diamond mat with a thermoplastic resin component and to excellently knead even noncompatible resins with each other in addition thereto by utilizing a thermosetting resin component as a matrix and micro-dispersing a particulate thermoplastic resin component in an island shape. CONSTITUTION:Both a thermosetting resin component 19a and a thermoplastic resin component 19b are supplied into the hopper 2 of a biaxial screw extruder 1. These resin components are kneaded while being transferred. The molten material is obtained wherein particulate thermoplastic resin component 19b is micro-dispersed into the sea of a matrix made of the thermosetting resin component 19a in an island shape by shearing force. A monomer is mixed from a second supply port 3b and the mixture is made to low viscosity at the comparatively low temp. A reaction initiator dissolved into the monomer is introduced from a third supply port 3c and a reactive kneaded material 7 made to low viscosity is produced and continuously discharged from a die 5. A diamond mat 6 is continuously carried by a belt 8. The diamond mat 6 applied with the discharged reactive kneaded material 7 is pressurized by rolls and shaped into a sheet shape and transferred. Since the respective rolls are cooled with water, the reactive kneaded material 7 is cooled and SMC 15 is formed.
