Metal-carbon fiber reinforced resin material composite and method for producing metal-carbon fiber reinforced resin material composite

Abstract

The metal-carbon fiber-reinforced resin material composite of the present invention includes a predetermined metal member, a resin layer located on at least part of the surface of the metal member, and a carbon fiber-reinforced resin material located on the resin layer, and the resin layer contains Inorganic fillers with a thermal conductivity of 20 W / (m·K) or more, the carbon fiber reinforced resin material contains a predetermined matrix resin and carbon reinforced fibers present in the matrix resin, and the carbon reinforced fibers have a thermal conductivity of 180 to At least one of pitch-based carbon-reinforced fibers in the range of 900 W / (m·K) and PAN-based carbon-reinforced fibers in the range of 100 to 200 W / (m·K) in thermal conductivity, the resin layer The content of the inorganic filler is in the range of 10 to 45% by volume relative to the total volume of the resin layer, and when the average particle diameter of the inorganic filler is X μm, the resin layer and the carbon fiber reinforced The number density of the inorganic fillers present in a region with a width of X μm in the direction of the interface of the resin material toward the resin layer is 300 / mm 2 above.

Description

technical field [0001] The present invention relates to a metal-carbon fiber reinforced resin material composite and a method for producing the metal-carbon fiber reinforced resin material composite. Background technique [0002] In recent years, various thermal managements have been required for automobiles. For example, in order to manage heat generated by batteries included in electric vehicles and hybrid vehicles, and to ensure battery safety and battery life, attention has been paid to components with high thermal conductivity. Specifically, the heat generated by the battery is managed by arranging a thermally conductive sheet, a copper heat pipe, or the like on the side surface portion or the bottom surface portion of the battery case. [0003] The above-mentioned thermally conductive sheet uses a member such as a resin (silicon) sheet from the viewpoint of reducing the weight of an automobile, but there is a problem that the strength of the resin sheet is lowered due ...
