Despite extensive investigations on the energy absorbing capabilities of fibre reinforced polymer (FRP) composite absorbers under axial loading, the off-axis crashworthy behaviour of composite absorbers remains unknown. In the present paper, published by School Aerospace & Aircraft Engineering-Kingston University- London,   the effects of stitching on the crack growth resistance, energy absorption and also off-axis crashworthy behaviour of CFRP composite box sections will be studied. The analytical methods are implemented to investigate the effect of various failure modes such as bending, friction, bundle fracture, and interlaminar crack growth for the observed crushing modes.
