Title:
COMPOSITE MATERIAL FOR MOLDING A FIBER-REINFORCED PLASTIC AND FIBER-REINFORCED PLASTIC MOLDED BODIES
Document Type and Number:
WIPO Patent Application WO/2013/129540
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a composite material for molding a fiber-reinforced plastic that enables fiber-reinforced plastic molded bodies to be continuously produced in an efficient manner by heat and pressure molding, said fiber-reinforced plastic molded bodies having high heat resistance, flame resistance and low smoke properties. The composite material for molding a fiber-reinforced plastic is characterized by containing: a reinforced fiber component comprising at least one type of inorganic fiber selected from a glass fiber and a carbon fiber; and a matrix resin component comprising thermoplastic super-engineered plastic fibers having a limiting oxygen index of not less than 25, a fiber diameter of not more than 30 μm and not more than four times the fiber diameter of the reinforced fibers. The composite material for molding a fiber-reinforced plastic is further characterized by comprising a nonwoven sheet containing a reinforced fiber component comprising inorganic fibers, a matrix resin fiber component comprising polyetherimide fibers, and at least one type of binder component, said fiber components in the surface layer of the nonwoven sheet being bonded by the binder component, which exists locally in a paddle-like film form mainly at the intersection points of the fiber components.
