Carbon fiber Ti-Ai composite material and method for preparation thereof

摘要

To provide a carbon fiber Ti—Al composite material having hardness, heat resistance and abrasion resistance, having reduced weight and improved strength and thermal conductivity and being excellent in uniformity of the quality. A carbon fiber Ti—Al composite material which is prepared by pressure impregnating a molded product containing fine carbon fibers having a fiber diameter of from 0.5 to 500 nm and a fiber length of at most 1,000 μm and having a hollow-structured central axis and a titanium powder or a titanium oxide powder, with aluminum or an aluminum alloy by molten metal forging.
