Title:
ミクロンサイズおよびナノサイズの炭素繊維を共含有する金属基複合材料
Document Type and Number:
Japanese Patent JP5364905
Kind Code:
B2
Abstract:
An object of the present invention is to provide a metal-based carbon fiber composite material that exhibits an improved thermal expansion coefficient and an improved thermal conductivity, and is smaller in weight. The metal-based carbon fiber composite material of the present invention comprises a metal and a carbon fiber comprising a micron carbon fiber and a nanofiber; the composite material having a first surface; the micron-size carbon fiber being oriented in one direction parallel to the first surface of the composite material, and being continuous from one end to the other end; at least 80% of the nanofiber being oriented at an angle within 30° with respect to the first surface; and the nano-size carbon fiber being oriented randomly in a plane parallel to the first surface. In the metal-based carbon fiber composite material, a surface region thereof may comprise a smaller amount of the micron carbon fiber than that in another region, or comprise no micron carbon fiber; and the nanofiber may have an orientation parallel to the surface of the composite material. The present invention provides a method for producing these composite materials.
