Strength Behavior of Graphite/Epoxy Composite Laminates under Biaxial Load.

Abstract

The room temperature mechanical ply properties of Fiberite hy-E 1034C graphite/epoxy composite material were characterized using unidirectional thin wall tubes and flat coupons. Four ply laminated tubes having (0/90)s and plus or minus 45)s stacking sequences were fabricated in preparation for biaxial experiments to determine first ply failure (FPF) thresholds. Initial results using acoustic emission techniques to detect FPF on (0/90)s tubes are reported.
