炭素繊維強化ポリカーボネート樹脂組成物からなる成形用材料
Document Type and Number:
Japanese Patent JP7116198
Kind Code:
B2
Abstract:
The present invention provides a molding material comprising a carbon fiber-reinforced polycarbonate resin composition, said molding material having superior flame retardancy, external appearance, strength, and colorability. In this molding material, 50-2,000 parts by weight of a polycarbonate resin composition is adhered to a readily impregnable carbon fiber bundle that comprises 100 parts by weight of carbon fibers and 3-15 parts by weight of one or more types of impregnation aid. The molding material is characterized in that the polycarbonate resin composition includes (C) 10-20 parts by weight of a bromine-based flame retardant (C component), (D) 0.01-2 parts by weight of a fluorine-including drip prevention agent (D component), and (E) 0.05-2 parts by weight of a full ester (E component) of a polyvalent alcohol and an aliphatic carboxylic acid, per 100 parts by weight of a resin component that consists of (A) 1-100wt% of an aromatic polycarbonate resin (A component) and (B) 0-99wt% of a polycarbonate-polydiorganosiloxane copolymer resin (B component).
