Abstract

The aim of this work is to experimentally explore the potential of using the thin ply angle-ply concept for achieving compressive pseudo-ductility in carbon fibre laminates. A laminate with a [±27₇/0]_s configuration was selected and tested in compression, via a sandwich beam subjected to four-point bending. From the moment versus strain curve, a significant amount of non-linearity has been observed and an average failure strain of 1.08% has been attained. Visual damage observation of a single fracture parallel to the angle-ply direction and the high shear stress suggest that the compressive failure can be attributed to the low ply shear strength.
