Abstract

Deformation and fracture behaviour in mode I delamination of carbon fibre/polyetheretherketone (PEEK) composites is studied. The results show that the initial crack propagation is along the boundary of the matrix-rich region in front of the starter defect and through the fibre-matrix interface, which suggests that the values of G_IC obtained from this region represent the delamination resistance of the matrix. With other published work, this paper suggests that the G_IC,Init represents the delamination resistance of the matrix in the composites. A new technique is developed for studying the deformation behaviour of composites. Using this technique, debonding of fibres and shear deformation in the matrix of the composites have been observed.
