Delamination is one of the main damage mechanisms in composite materials, and a material’s resistance to it is characterised by interlaminar fracture toughness. This property is used in finite element material models and delamination simulation methods, such as the virtual crack closure technique. By definition, delamination takes place in the inter-ply region composed mostly of resin, which can notoriously have strain rate-dependent mechanical properties. Rate dependence of interlaminar fracture toughness needs therefore to be studied in order to develop material models usable in highly dynamic simulations, e.g. those of automotive crash absorbing structures. To date, no standardised dynamic delamination test exists.
