Joining of Carbon Fibre Composites and Foams for Impact Energy Absorption
Original language description
Common property of composites and foams is their low specific weight. A utilization of these two materials in suitable combination allows the creation of lightweight impact energy absorbers where composite layers advantageously distribute impact forces into foam layers. This paper deals with carbon fibre reinforced plastic (CFRP), expanded polystyrene (EPS), and open-closed cell foam (OCCF). EPS is crushable foam commonly used in personal protective equipment, OCCF is modern energy absorbing material having different mechanical response according to strain rate. The aim of this work was the investigation of the impact force response of these materials. The response was investigated experimentally using a drop tower designed by the authors and numerically using the finite element method in ABAQUS software. The obtained results were used in design of a versatile sport helmet. The helmet consists of outer CFRP shell, EPS liner which fit tightly the CFRP shell, and inner OCCF liner.
