This paper presents a design and experimental works aiming to develop a composite crashbox suitable for a 1000 parts/day production at low cost and adapted to current mass market vehicle design. Various matrixes (Epoxy, fast-curing epoxy, polypropylene and low viscosity polyamide), various preform type in including interlock textile (Glass or carbon fiber, braided or weaved) and various manufacturing process has been evaluated by axial and 15° of-axis crash test. Solutions for short term development are proposed, with 66% weight reduction compared to current steel parts, and an estimated price of less than 5€ per saved kilogram.
