METAL-BASEd CARBON FIBER COMPOSITE MATERIAL AND PRODUCTION METHOD THEREOF

摘要

The invention provides a metal-based carbon fiber composite material that can be prepared with commonly used cheap materials and less energy than in a melt method, has a wide range of dimensions and shapes (particularly large area) and is excellent in the thermal conductivity and light in weight. The metal-based carbon fiber composite material can be obtained by heating and pressure welding a metal and carbon fibers and has a structure in which a metal layer and a carbon fiber-containing metal layer are alternately stacked. The metal-based carbon fiber composite material can be produced by a method comprising the steps of: adhering carbon fibers on a sheet or foil metal support to form a preform; stacking the preforms to form a preform laminate; and heating and pressure welding the preform laminate in a vacuum or non-oxidizing atmosphere to unite the preforms together.
