Abstract

T300 carbon fibre/epoxy composite specimens with unidirectional and cross-ply orientation and G802 woven fabric/epoxy specimens were tested in a pin-ended rig at various specimen geometries. The rig was designed so that a combination of bending and compression was possible. Failure initiation and failure sequences at the midspan were monitored and established through photography. In some specimen geometries, high compressive strains of the order of $\sim$1.85% for pin-ended tests, accompanied by a higher loadbearing capacity than in conventional bend tests, were observed. Fracture characterization and failure analysis were carried out with the aid of a scanning electron microscope.
