An automotive frame rail of hourglass cross section, made of a glass fibre/vinylester composite, was designed for use in the apron construction in order to obtain a high degree of crashworthiness at this location of the car body. The crashworthy behaviour of this structural component in axial compression at various strain rates (head-on collision) and in bending (oblique collision) was studied experimentally. The modes of collapse at macroscopic scale, the microscopic fracture patterns and the energy absorbing capability of such rail beams were examined and discussed.
