Investigation of First Ply Failure in Graphite/Epoxy Laminates Subjected to Biaxial Static and Fatigue Loadings

Thin graphite/epoxy (0/90)s and (+ or - 45)s tubes were loaded in various combinations of tension, torsion, and internal pressure, and physical evidence of first ply failure (FPF) was found using replication techniques. The FPF envelopes so identified were compared with ultimate strength envelopes,...
