Abstract

Pseudo-ductile metal-like tensile stress-strain responses with 700 MPa "yield stress" plateau and 4.0% failure strain have been achieved experimentally using thin-ply carbon epoxy prepreg and [+26_n/0]S (n = 8 and 10) layups. Analysis of tested specimens has been conducted using microscopy and ultrasonic C-scan. These show that periodic fibre breakages in the 0° plies lead to local delaminations that propagate along the 0°/ - 26° interfaces. This gradual failure process of fragmentation and dispersed local delamination allows the demonstrated pseudo-ductile strains.
