ABSTRACT:
An aluminum torpedo piston is provided with a piston head fabricated from a etal matrix composite material composed of aluminum and silicon carbide fibers that are integrally joined by an inertial welding technique. A 23% weight of silicon carbide fibers to powdered aluminum was selected. Resistance to intense heating which would otherwise cause melting and erosion of the piston is avoided to permit longer, high speed runs.
