Composite Thin Film Pilot Plant.

Abstract

Tooling was designed and fabricated for the high rate vacuum deposition of alternating superimposed layers of high and low modulus materials. A continuous metal belt substrate was passed over adjacent electron beam and resistance heated sources. Composite films of titanium-aluminum, silicon carbide-aluminum and alumina-aluminum, were fabricated, removed from the substrate and their ultimate tensile strengths determined. Tensile strengths a number of times bulk values were obtained for the titanium-aluminum films which exhibited the highest ultimate tensile strength. The ultimate tensile strength was determined using an internal clamp technique which was analyzed empirically and theoretically.
