In the present research, the flexural and compressive behavior of foam-filled sandwich panels M-shaped core with hybrid carbon-glass fiber composite have been experimentally investigated. In order to fabricate the sandwich panels, the vacuum assisted resin transfer molding (VARTM) has been used to achieve a laminate without any fault. Afterward, polyurethane foam with density of 80 Kg/m3 has been injected into the core of the sandwich panel. The flexural and compressive properties of sandwich panel with hybrid carbon-glass fiber [CGCG]s have been compared to those of eight-layered carbon fiber [C]8 and the eight-layered glass fiber [G]8. The study of force-displacement curves obtained from the compressive and three-point bending tests showed that the [CGCG]s has larger elastic region than [C]8 and larger plastic region than [G]8. Also, it was found that polyurethane foam enhanced the ultimate compressive and bending loads and absorber features of sandwich panels Finally, the extra foam coming out of the sides of the sandwich panel is cut after rigidization.
