Description Hybrid composites consist of two or more types of fibres and/or matrices in a composite. By combining two or more types of fibres, it is possible to club advantages of both the fibres while simultaneously mitigating their less desirable qualities. Investigations on high strain-rate behaviour of a typical hybrid composite under compressive loading are presented. The hybrid composite is made using satin weave carbon and plain weave E-glass with epoxy resin. Studies were also carried out on satin weave carbon/epoxy and plain weave E-glass/epoxy. Compressive split Hopkinson pressure bar (SHPB) apparatus was used for the studies. Compressive properties were evaluated along all the three principal directions in the strain-rate range of 546ā€“1503 sāˆ’1. During SHPB testing of the specimens, it was observed that the peak force obtained from the strain gauge mounted on the transmitter bar is lower than the peak force obtained from the strain gauge mounted on the incident bar. The explanation for this is provided based on stress wave attenuation studies.
