Improvement of Transverse Strength in Graphite-Aluminum Composites by High-Strength Surface Foils.

Abstract

Graphite-aluminum composites were fabricated having special high-strength surface foils. The foils employed were an aluminum powder metallurgy alloy (IN9051) and a SiC-Al composite. Both improved the transverse strength of graphite-aluminum panels above that achieved with 6061 aluminum foils. The transverse strength of panels having the IN9051 foil was three times that of panels with 6061 foils of equivalent thickness. The primary effect of the SiC-Al foil was an improved elastic modulus in the transverse and longitudinal directions. The IN9051 foils had no effect on the composites' longitudinal strength, but the SiC-Al foil degraded the longitudinal strength. (Author)
