Abstract: Light metal/CFRP-made structural members which are characterized in that they are structural materials in which a CFRP material is stuck to the surface of a light metal material via an adhesive agent layer of thickness at least 10 &mgr;m and up to 500 &mgr;m, and the volume resistivity of the adhesive agent layer between said metal material and said CFRP material is at least 1×1013 &OHgr;.cm and, furthermore, the adhesive strength at room temperature is at least 15 MPa. In accordance with the present invention, since conventional light metal/CFRP structural materials can be made lighter and, furthermore, since the resistance to galvanic corrosion is outstanding and it is possible to markedly enhance the strength and the impact energy absorption performance, the development of applications and large-scale expansion into new fields becomes possible. Weight reduction and enhancing the durability and reliability of structures also makes a considerable contribution in terms of environmental protection.

Abstract: A thermoplastic resin composition capable of providing a thin walled molded article whose flame retardancy with a thickness of 1.6 mm ({fraction (1/16)} inch) in accordance with an UL 94 standard is V-0 or better, and which comprises the following components [A], [B] and [C], wherein the component [B] satisfies the following conditions (B1) and/or (B2): [A]: an electrically conductive fiber; [B]: a carbon powder; [C]: a thermoplastic resin; (B1): Raman scattering intensity ratio I2/I1 is 0.55-0.8; (B2): Raman scattering intensity ratio I2/I3 is 0.54-0.8;  where I1: local maximum value of Raman scattering intensity appearing near a Raman shift of 1360 cm−1; I2: local minimum value of the Raman scattering intensity appearing near a Raman shift of 1480 cm−1; I3: local maximum value of the Raman scattering intensity appearing neat a Raman shift of 1600 cm−1.

Abstract: The present invention relates to a carbon fiber reinforced plastic member provided with high-elongation fiber bundle regions, which are uni-directionally aligned and separately disposed within the plastic member. The plastic member provides a carbon fiber reinforced plastic of lightweight, high strength and high modulus that is safe. Even if it breaks, it shows little scatter of fragments or exposure of dangerous fracture surfaces. Preferably, the high-elongation fiber at break has an elongation exceeding about 10%.

Abstract: A fiber or filament comprising a polyester copolymerized with 2 to 20 mole % of a compound having a specific structure, which has one or two ester-forming functional groups. The polyester fiber or filament has a low birefringence and excellent dyeability and deep color development. The polyester fiber or filament is provided, when drawn under selected conditions, with not only high shrinkage ratio but also high shrinking stress, and has excellent lightfastness, thereby being useful while replacing conventional highly shrinkable fibers.
