Metal matrix composite co carbon nano-sized fibers and micron-sized

摘要

An object of the present invention is that the thermal expansion coefficient and thermal conductivity is improved, and to provide a metal-based carbon fiber composite material which is lightweight. Consists of carbon fibers containing a metal, the nanofibers and micron carbon fibers, this material has a first surface, a metal-based carbon fiber composite material of the present invention, the first of said composite material wherein the micron carbon fibers is oriented towards a direction parallel to the surface of, and is continuous from one end to the other end, the nanofibers are oriented at 30 ° to the surface within the first 80%, and I have randomly oriented in a plane parallel to the surface of the first. The surface area, is not present at all micron carbon fibers is less than or other area, the nanofibers may have an orientation parallel to the surface of the composite metal-based carbon fiber composite material. The present invention provides a process for the production of these composite materials.
