PURPOSE: To produce a continuous fiber reinforced titanium-based composite material capable of exhibiting strength exceeding a specified percentage of theoretical density by ROM.
CONSTITUTION: Titanium alloy sheets each consisting of, by weight, 3-7% Al, 2-5% V, 1-3% Mo, 1-3% Fe, 0.06-0.20% O and the balance Ti with inevitable impurities and continuous SiC fibers arranged in one direction are alternately piled up and hot-pressed under the conditions of 700-850°C heating temp., ≥5MPa pressure and ≤10Hr pressing time in vacuum at ≤10-1Pa degree of vacuum or in an inert gaseous atmosphere to produce the objective continuous fiber reinforced titanium-based composite material contg. a titanium alloy matrix having the above-mentioned compsn. and continuous SiC fibers arranged in the matrix in one direction.
