• Resumen

  • Sandwich panels are widely used in various industries, including the aerospace industry, where they have long been regarded because of their light-weight and high energy absorption capacity. This research introduces a novel type of sandwich panel whose raw material is widely used in the automotive industry. The materials used for manufacturing the sandwich panels addressed in this research are currently used in the cooling radiator structure for the engine of conventional vehicles. Such a radiator is nothing but a lattice of a set of B-shaped tubes and cooling fins. In this research, the crashworthiness properties of such a lattice are extracted along with various directions (samples A, B, and C). Moreover, the applicability of the considered lattices as the core of sandwich panels was studied. This research showed that the considered structures tend to exhibit maximum strength when the loading plane is parallel to the cooling fins. It was further figured out that the addition of aluminum shells to specimens A, B, and C can increase their energy absorption capacity by 85, 268, and 13%, respectively
