Abstract: A fiber-reinforced thermoplastic resin composition includes 5 to 50 parts by weight of reinforcing fibers (A) containing at least carbon fibers, 20 to 94.5 parts by weight of a thermoplastic resin (B), and 0.5 to 30 parts by weight of a rosin resin (C), wherein the rosin resin (C) has an acid value and/or hydroxyl value of 100 mgKOH/g or more. Since the fiber-reinforced thermoplastic resin composition contains the reinforcing fibers containing at least carbon fibers and the specific rosin resin, a fiber-reinforced thermoplastic resin molded article high in reinforcing effect due to the reinforcing fibers and excellent in tensile strength, impact strength and appearance quality, particularly blackness, can be obtained.

Abstract: An epoxy resin composition is provided which includes a poly-naphthalene-based epoxy resin having two or more epoxy groups per molecule combined with a non-linear multi-phenyl epoxy resin and an additional epoxy resin having an epoxy functionality of 3 or more, as well as a prepreg, and a fiber-reinforced composite material prepared using the epoxy resin composition. More specifically, an epoxy resin composition is provided which contains a combination of particular types of epoxy resins and curatives that, when cured, provides high flexural modulus and that is suitable for preparing a fiber-reinforced composite material capable of withstanding extreme use environments such as low-temperature environments and high-temperature moisture-absorbing environments. In addition, epoxy resin systems are provided which are capable of achieving a high Tg along with good thermal stability for long periods of time at elevated temperatures (e.g., 180° C. or more) when cured at 210° C. for 2 hours.
