The idea of hybrid sandwich structures made of polymeric sheets and RVC foams represents a new research topic which is directly related to the interaction between thermal shock wave and structural insulation panels, dynamics of thermal motions, delamination effect during the compression loads and fracture mechanism of the structure. The RVC (reticulated vitreous carbon) foams are very attractive for aerospace industry, especially for impact absorption. Development of hybrid sandwich system made from polymeric composite materials presumes a high degree of complexity. Aspects such as the conception, design and construction of both the materials and the product itself are corroborated taking into account the properties of the materials and the functional need. The technical approaches of this paper are mainly focused on the compression behavior of the hybrid sandwich composite structure, being the first step in finding an optimal structure for the system. The behavior will be analyzed using the microscopy technique.
