INVESTIGATION OF THE IMPACT PROPERTIES OF ULTRA-HIGH-MODULUS POLYETHYLENE(UHMPE) FIBRES-CARBON FIBRES HYBRID COMPOSITE MATERIALS

The impact behavior of ultra-high-modulus polyethylene( UHMPE)fibre/carbonfibre/epoxy hybrid composites was investigated by notched and unnotched Charpy impacttests. The results showed that hybridizing carbon fibres with UHMPE fibresled to an increase in the impact strength of the hybrid composites. Based on the load-time curves of the specimens during impact and the morphology of the specimens after impact, the failure modes of the hybrid composites were analyzed in detail.
