Axial energy absorption of CFRP truncated cones

Truncated cones made of composite materials, intended for structural applications in the automotive industry, have been studied from the point of view of their energy absorption capability when submitted to axial loading. The study has been developed at first applying quasi-static loads and then dynamic impact ones. The material used for this research is a fabric prepreg obtained by high-strength carbon fibers embedded in an epoxy resin. Three...
