A Comparison of the Delamination and Environmental Resistance of a Graphite-Epoxy and a Graphite-Bismaleimide.

Abstract

The objectives of this program were to compare the delamination and environmental resistance of a graphite-epoxy system (AS1/3501-6) and a graphite-bismaleimide system (T300-6K/V378A). An experimental program was conducted to determine critical values of strain-energy release rate for Mode I (peel) and Mode II (forward shear) delamination. Static delamination fracture and constant amplitude fatigue delamination growth rate data were obtained from dry specimens at -65 F, 75 F, 300 F, and 350 F, and on moisture-conditioned specimens at -65 F and 75 F.
