Three point bend tests were used to evaluate the critical energy release rate G c for delamination under elastic linear and plane strain conditions. A value of G c of 2·8 kJ m −2 was obtained which is considerably lower than the energy for crack propagation across the layer. The given G c corresponds to a critical stress intensity factor K c of 25 MPa m 1/2 . These low values are responsible of delamination and, therefore, of the 34% improvement in toughness of the laminate with regard to the monolithic material.Read More
