Origami cores have the advantage of stiffness to weight ratio over conventional sandwich cores. The main idea of designing sandwich cores is to have low-density structure with high stiffness, that allows the sandwiches to withstand compression and impact loads. Recently, the implementation of origami cores in sandwich structures has attracted engineers to design and investigate different types of origami cores for compression and impact applications. Such cores can give the sandwich structure, high stiffness to weight ratio, and they can dissipate the incoming loads by high strain deformation. In this work, we study numerically and experimentally, two different origami configurations; the study investigates origami unit cells’ and cores’ stiffness and load resistance. Origami unit cells and cores are fabricated with fused deposition modeling. The results of the numerical simulation validated with the experimental results.
