The reinforcements in the thickness of the sandwich structures represent one of the technological solutions that improve the mechanical properties of this type of structures. We are talking about 3 D sandwich structures. In this work, the equivalent properties of reinforced sandwich structures in the thickness are evaluated. The finite element analysis homogenization is used to calculate the equivalent mechanical properties of foam reinforced by circular glass fiber reinforcements at ± 45°. This study shows the interest of reinforcing sandwich structures in the thickness. All the results show that the improvement of the mechanical properties is significant, especially the properties in normal and shear in the out-plane direction. \textcopyright CCM 2020 - 18th European Conference on Composite Materials.
