Patent ID: 8012574

Claim:
A carbon fiber Ti—Al composite material, comprising: 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, at least one of a Ti powder and a TiO 2 powder, and a Ti—Al composite, wherein the carbon fibers and at least one of the Ti powder and the TiO 2 powder are dispersed in the Ti—Al composite; and wherein the carbon fiber Ti—Al composite material is prepared by pressure impregnating a mixture containing the 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.
