Abstract

<p>Hybrid composites combining brittle and ductile reinforcing fibres can achieve a superior combination of stiffness and toughness in comparison to the conventional single fibre type composite materials. The recently developed carbon fibre/self-reinforced polypropylene hybrids have demonstrated a unique combination of stiffness and toughness. Further optimisation of these hybrids can be achieved through modelling. This paper explores the capabilities and limitations of an analytical modelling technique. It was found that the sequence of the failure events, which depend on the critical stresses, and the overall shape of the stress-strain curve can be predicted analytically. Further work is required to accurately predict the critical strain values, which are needed for the estimation of the ultimate failure strain.</p>
