Abstract

Through a systematic experimental analysis, the impact characterization of carbon-aramid hybrid composites, typically used in the automotive sports field, has been performed. CFRP laminates object of this study have been produced by adding a hybrid foil obtained using a fabric of twill type, so-called carbon-kevlar. In order to highlight the effects of hybridisation, that is, the different properties of kevlar fibre with respect to carbon, a comparative analysis was also carried out considering a CFRP laminate with the same lay-up. The analysis of the experimental results obtained through preliminary tensile tests and subsequent low-velocity drop-weight impact tests integrated with x-ray tomography, showed that although the hybrid composite has a lower static strength than the simple CFRP, it has an increase in impact strength of up to 50%, combined with an appreciable increase in maximum impact force and mainly in resistance to surface damage.
