Abstract
A filament-reinforced composite article is fabricated from monolayer boron fiber tapes and laminates of titanium. The tapes which have the boron fibers attached to an aluminum foil are positioned in a multi-ply layup with interleaved titanium laminates in the form of foils or screening. The layup is subjected to heat and pressure in a diffusion bonding process to compact the layup materials and bond the fibers in the matrix of aluminum and titanium. The titanium in the matrix improves the impact load resistance of the article by improving ductility and impact strength.
