Abstract : This invention relates to a method for fabricating filament reinforced composite articles. In particular, this invention is directed to a method for fabricating filament-reinforced titanium aluminide matrix composite materials. Composite metallic structures, which are reinforced with high strength, high modulus filaments or fibers having a high specific properties. With particular respect to the aerospace industry, titanium-based composites have been considered for high temperature applications because of the high-temperature strength and low density of titanium and its alloys. Fiber-reinforced titanium-based composites exhibit increased temperature capability, improved shear, transverse, and off-axis properties; and better erosive environment durability when compared with presently available aluminum matrix and polymeric matrix composite systems.
