<P>PROBLEM TO BE SOLVED: To provide a composite resin composition which is more excellent in molding processability, lightweight properties, and heat radiation properties than a metal material and more excellent in thermal conductivity and mechanical strength than a resin material. <P>SOLUTION: The composite resin composition includes (A) heat conductive fibers and (B) resin as constituent materials. In the composite resin composition, thermal conductivity in a planar direction measured based on the laser flash method in a molded article obtained by molding the resin composition is 5 W/mK or more, the thermal conductivity in the thickness direction is a half or less the thermal conductivity in the planar direction, the bending strength measured based on JIS K 6911 is ≥80 MPa, and the bending elastic modulus is ≥8 GPa, the specific gravity is ≥1 and ≤5 measured based on JIS K 6911, and the linear expansion coefficient in the planar direction is ≥0.1 ppm/°C and ≤50 ppm/°C. The molding excellent in heat conductivity is produced by using the composite resin composition. <P>COPYRIGHT: (C)2013,JPO&INPIT |
