Flexural Behavior of Stepped Graphite Epoxy Laminates
Polymer Composites
Abstract
Cross-ply tapered/stepped laminates with taper angles of 1 and 2° between the top and bottom surfaces were fabricated using T300/934 graphite/epoxy by compression molding. Ply terminations were done internally within the laminate and externally on the surface of the laminate at various cross-sections in order to obtain the taper. Equivalent cross-ply specimens with internal and external ply terminations, respectively, were tested in three point bending. the tapered laminates with internal ply terminations failed due to a series of delaminations originating at the step corners of the 0° plies. Macroscopically, the specimens with internal ply term nations failed by tensile fracture of the outer plies at relatively higher loads.
