The paper presents an experimental work pertaining to the energy absorption capability of FRP specimens. The tests were performed on the INSTRON 8802 universal testing machine and the energy absorbed by the structure was calculated from the load-shortening diagram. A series of experiments were performed for composite thin walled tubes and cones with different semi-vertex angles ranging from 5° to 20°. The specimens were made of epoxy (E-53) and vinylester (VE-2MM) composites with glass, carbon and aramid fibers in three forms: filament yarn, fabric and mat. The influence of specimen geometry, fiber orientation and composite structure on the energy absorbing capability was studied. In particular relative energy of absorption (WEA) in dependence on materials, typical dependence of a crushing force on displacements (shortenings), comparison of mechanical properties of epoxide, monotropic composites strengthen with glass and carbon fibres, comparison of mechanical properties of epoxide, orthotropic composites strengthen with glass and carbon materials, dependence of the destructive strength on displacement of carbon/epoxide composite, progressive destruction of a specimen made of carbon/epoxide composite, mechanism of destruction by layer bending, influence of the thickness of the cone wall on the ability of absorbing energy by the epoxide composite, dependence of WEA on the angle alfa for the chosen structures of composites are presented in the paper.
