Investigation of non-metallic and polymeric composite materials (FRP - fiber reinforced plastics) response to impact loading is now one of the most actual problems of experimental mechanics. This paper describes current results in the field of dynamic investigations, when magnitude of inertial force becomes near equal to resistance force of the test sample. Time of loading up to rupture becomes very small under high strain rates. These two factors mainly define peculiarities of material dynamic testing. For composites these problems become more complicated because of high anisotropy of material elastic and strength properties.
