Meyn, D A; Shahinian, P

The effects of strain rates from 0.00008 to 0.4/sec on tensile strengths and moduli of 6061 aluminum-46.5 vol% boron at temperatures up to 1000 deg F, of unidirectional and cross-ply epoxy-50 vol% boron composites at temperatures up to 500 deg F and of crossply epoxy --80 vol% graphite composites at temperatures up to 250 deg F were measured. Longitudinal properties were reduced moderately at high temperatures and were only slightly higher at high strain rates than at low strain rates. Transverse properties decreased rapidly with temperature and were either unaffected by high strain rates, particularly at low temperatures, or were substantially increased, especially at high temperatures, in both aluminum- and epoxy-based systems.
