Mode II interlaminar failure mechanisms in carbon fibre / PEEK and carbon fibre / epoxy composites

The mode II interlaminar fracture properties of two high performance composites have been examined in detail. The failure mechanisms occurring in these materials are investigated using the double end-notched flexure (DENF) geometry. Tests have been undertaken at crosshead displacement rates betwe...
