Abstract

This article presents original experiments that enhance the understanding of the mechanisms that drive the progressive crushing of fiber-reinforced laminated composite materials and their energy absorption capability. An innovative experimental fixture has been created in order to obtain detailed monitoring of quasi-static and dynamic crushing of laminated plates. The fixture enables the development of a regular crushing front through the whole width of the plate, without parasite rupture modes, and the real-time observation of this front with a high speed camera. Results of experimental works on fabric and unidirectional Carbon-Epoxy laminated composite plates are exposed. The obtained crushing modes are analysed, their stability and energy-absorbing capability are discussed.
