Title:
FIBER-REINFORCED THERMOPLASTIC RESIN COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2023/058448
Kind Code:
A1
Abstract:
A fiber-reinforced thermoplastic resin composition comprising 5-50 parts by weight of reinforcing fibers (A) at least including carbon fibers, 20-94.5 parts by weight of a thermoplastic resin (B), and 0.5-30 parts by weight of a rosin resin (C), wherein the rosin resin (C) has an acid value of 100 mgKOH/g or greater and/or a hydroxyl value of 100 mgKOH/g or greater. Due to the inclusion of both the reinforcing fibers at least including carbon fibers and the specific rosin resin, this fiber-reinforced thermoplastic resin composition has the high reinforcing effect of the reinforcing fibers and can give molded fiber-reinforced thermoplastic resin articles excellent in terms of tensile strength, impact strength, and appearance quality, particularly blackness.
