Abstract

This invention includes a continuous in-plane spiral of monofilament/metallic ribbon which forms a preform for metal matrix composite fabrication. The purpose is to provide continuous spiral filament reinforcement around a hole or central core. This spiral monolayer is fabricated by co-winding the filament and a ribbon or wire made from the intended composite material around a mandrel. Monolayers so constructed could then be stacked to form cylindrical or torus-shaped components and consolidated in a direction parallel to the axis of the shape.
