Thickness properties of laminated composites have not been as thoroughly investigated as in plane properties. Previous work by this investigator indicated that these properties, both elastic and strength, differ significantly from the transverse properties of unidirectional composites of the same materials system although the thickness direction is transverse to each play in the laminate. In this investigation the thickness properties of both single system, and hybrid laminates are studied namely, graphite-epoxy, kevlar-epoxy, glass-epoxy, graphite-epoxykevlar-epoxy, graphite-epoxyglass-epoxy. However, knowledge of the in-plane properties of the laminates was also obtained since this was essential for the analysis and are also reported. Failure modes of the hybrid composites are characterized and discussed. Composites, Laminated composites, Laminates, Graphite-epoxy, Kelvar-epoxy, Glass-epoxy, Hybrid composites.
