Abstract

In this research, influence of foam filling technique in double layer trapezoid-shape corrugated core by using lightweight Rigid polyurethane foam is investigation. Five types of Aluminum corrugated cores both bare and foam-filled were subjected to unidirectional quasi-static compression. In the following, using Numerical simulation by Abaqus software to evaluation the impact parameters, including Specific Energy absorption (SEA) as discussed testing purposes. The energy absorbing system can be used in the aerospace industry, shipbuilding, automotive, railway industry and elevators to absorb impact energy. The FEM results are compared with Experimental results which reveal a good conformity. FEM and experimental results showed that foam filling technique can significantly increase specific absorbed energy. Results show that the increase in core sheet thickness up to two times increases the specific Energy absorption by 509. 47 %. The results of axial crushing tests showed that the SEA of foam-filled sandwich panel increased by 91. 42%, comparing to the hollow panel. Also, double-layered core in the panel caused to increase the specific Energy absorption by 81. 42%. Finally, appropriate geometric parameters and the best examples of criteria considered with respect to the objectives, are introduced.
