Experimental Evaluation of Column Compression Properties of Graphite/Epoxy Composites

CODEN: JCTRER

Abstract

Experimental procedures for evaluating the column compression properties of graphite/epoxy laminated composites are described. The test procedure allows the determination of a buckling curve up to and including the inelastic, fully supported, zero-length column. Verification of the test procedure is provided by using flat aluminum test specimens. Application to specific graphite/epoxy laminated composites is described. Inelastic compression properties are shown to be highly sensitive to environmental conditions and laminate lay-up. Prediction of the elastic compression properties of graphite/epoxy laminates by the Euler relation is shown to be significantly nonconservative.
