Composite of metal and carbon-fiber-reinforced resin material, and method for manufacturing composite of metal and carbon-fiber-reinforced resin material

Abstract

A composite of a metal and a carbon-fiber-reinforced resin material is provided with: a prescribed metal member; a resin layer positioned on at least one surface of the metal member, the resin layer containing an inorganic filler having a thermal conductivity of 20 W / (m.K) or higher; and a carbon-fiber-reinforced resin material positioned on the resin layer, the carbon-fiber-reinforced resin material containing a prescribed matrix resin and carbon reinforcing fibers present in the matrix resin, the carbon reinforcing fibers being pitch-based carbon reinforcing fibers having a thermal conductivity within the range of 180-900 W / (m.K) and / or PAN-based carbon reinforcing fibers having a thermal conductivity within the range of 100-200 W / (m.K). The inorganic filler content in the resin layer iswithin the range of 10-45 vol% with respect to the entire volume of the resin layer. The number density of the inorganic filler present in a region extending to a width of X [mu]m toward the resin layer from the boundary between the resin layer and the carbon-fiber-reinforced resin material is 300 per mm<2> or higher, wherein X [mu]m is the average grain diameter of the inorganic filler.

Description

technical field [0001] The present invention relates to a metal-carbon fiber reinforced resin composite body and a method for manufacturing the metal-carbon fiber reinforced resin composite body. Background technique [0002] In recent years, automobiles have been required to manage various kinds of heat. For example, in order to manage heat generated by batteries of electric vehicles and hybrid vehicles, and ensure battery safety and battery life, attention has been paid to highly thermally conductive members in particular. Specifically, the heat generated by the battery is managed by arranging a heat conduction sheet, a copper heat pipe, or the like on the side surface or the bottom surface of the battery case. [0003] The aforementioned thermally conductive sheet uses a member such as a resin (silicon) sheet from the viewpoint of reducing the weight of the automobile, but there is a problem that the strength of the resin sheet decreases due to repetitive vibrations gener...
