EXPERIMENTAL ANALYSIS OF THE RUPTURE OF POLYESTER-WOOD COMPOSITE UNDER

Cover Page

Abstract


The work is devoted to experimental study of polyester-wood composite under dynamic loading. Based on a thermodynamic approach, the objective is the evaluation of the specific energy of interfacial delamination in a multi-layer composite material under dynamic loading causing damage to it by cracking. For modeling of dynamic loading, it was used an experi- mental device based on the principle of the Charpy test which is to measure the residual en- ergy of a mass movement following a shock at speeds generally between 1 and 4 m/s, on a test piece cut of standardized dimensions requested in bending. Some of the available energy is consumed by rupture of the test piece. The results of this work showed that for a dynamic test, the fracture energy is function of the speed and impact energy of fall of the load. These results may be useful in the design of multilayer composite structures subjected to dynamic loads
