Two types of interlayer hybrid composite specimens (continuous and discontinuous) were designed and tested at three different temperatures (-50°C, 25°C and 80°C). The continuous specimens fragmented at similar strains at all temperatures and showed a linear-plateau type pseudo-ductile behaviour. The discontinuous specimens started to delaminate at different strains proving that this matrix-dominated failure mode is significantly affected by test temperature. The determined mode II critical energy release rates of the discontinuous specimens also changed by up to +35% (at low temp.) and -15% (at high temp.) compared to the room temperature reference. It was observed that at low temperature some of the specimens changed their failure mode from delamination to fragmentation which confirms that the test temperature has a strong influence on the interlaminar behaviour of the hybrids. A diagram showing the margin between the actual and the critical energy release rate of a given configuration at a given temperature is very useful for failure mode prediction.
