Review on CFRP and Metal/CFRP hybrid thin-walled structures underaxial loading condition

Lightweight materials have attracted tremendous interests for their compelling advantages in a range ofengineering problems that have placed heightened requirements in safety, environment,competitiveness and cost over recent years.Light weighting becomes a main issue for energy efficiency in automotive industry, so they utilizehybrid composites in the interior and exterior applications. The best way to improve the fuel efficiencyand reduce emission of gases is to decrease the weight of vehicle parts.Hybrid systems aim to take advantages of different materials to maximize their functional roles inlightweight structures. This article provides a review on the advances in metal/CFRP hybrid materialssubjected to axial loads for crashworthiness performance.There arises a need for developing a novel generation of materials that will combine both weightreduction and safety issues. The application of carbon fiber reinforced plastic material offers the bestlightweight potential to realize lightweight concepts.Metal members absorb energy by stable plastic deformation, while CFRP members absorb energy byunstable brittle failure.
