Patent ID: 7955712

Claim:
Method for the production of a semifinished product of composite material, comprising a coating step in which high tensile strength fibers are coated with titanium or a titanium based alloy to form a coating on the fibers in a reactive atmosphere containing a reactive gas, a thermomechanical treatment step performed on the coated fibers after the coating step, and a consolidating step in which the coated fibers are then consolidated under pressure at high temperature to form the semifinished product characterized in that during the coating step atoms of the reactive gas are introduced into the titanium or the titanium based alloy, and then during the thermomechanical treatment step after the coating step the introduced atoms of the reactive gas react with the titanium or the titanium based alloy to form ceramic particles embedded in the coating of the fibers, and then during the consolidating step the thusly coated fibers are arranged in a desired geometry and consolidated to form the semifinished product.
