Abstract:
A composite of metal and carbon-fiber-reinforced plastic according to the present invention comprising a predetermined metal member, a resin layer positioned at a surface of at least part of the metal member and containing an inorganic filler having a thermal conductivity of 20 W/(m·K) or more, and carbon fiber reinforced plastic positioned on the resin layer and containing a predetermined matrix resin and carbon reinforcing fiber present in the matrix resin, the carbon reinforcing fiber being at least one of pitch-based carbon reinforcing fiber having a thermal conductivity of 180 to 900 W/(m·K) in range or PAN-based carbon reinforcing fiber having a thermal conductivity of 100 to 200 W/(m·K) in range, a content of the inorganic filler in the resin layer being 10 to 45 vol % in range with respect to a total volume of the resin layer, a number density of the inorganic filler present in a region of a width X μm from an interface of the resin layer and the carbon fiber reinforced plastic in a direction of the resin layer being 300/mm2 or more, where X μm is an average particle size of the inorganic filler.
