Abstract

In this research mixed-mode fracture behaviour of glass fibre/epoxy composite with randomly distributed glass fibres investigated. Various modes of loading were applied. Compact tension shear (CTS) fixture with different loading angles were used. The testing is used to measure the fracture toughness. Critical strain energy release rate (CSERR) of the composite was then calculated using the measured fracture toughness. A model is proposed to predict the value of CSERR based on the constituents and interfacial properties. Different failure mechanisms are considered in developing a criterion. To derive the criterion a FE model is used to determine the amount of energy released during the fibre pull out which is major part of energy dissipation.
