This paper presents an experimental study about 3 sets of composite materials: glass fibers MAT 300, COREMAT and composite sandwich with glass fibers MAT 300 and COREMAT core. In today's society, the automotive industry is constantly evolving and perfecting, which requires finding new materials, compatible with new trends: reducing the weight of car, increasing corrosion resistance, increasing protection against shocks, increasing comfort, increasing operational safety, using an expanding variety of technologies or reducing the cost of production. We made a new composite material, a composite sandwichwith COREMAT core. Due to results obtained in this work, this composite sandwich will be used to make some car elements, which will be studied at impact in future research.
