We found, that shear strength is slightly dependent on the compression load when the angle between layer orientation and load direction is in the range 30-60 degrees and increases 2 times at the angle 75 0 . Material is strain rate sensitive but the behavior of the shear strength is the same at the high strain rates. transversal direction. Keywords: carbon fiber laminate; shear strength;biaxial load; dynamic load 1. Main text Carbon fiber reinforced polymer composites are widely used as a protective casing against impact. Thus, the determination of the material properties at high strain rates is important for modelling the progressive damage of laminates under low velocity impact. In most of cases the shear strength is believed to be independent on compression stress (Shi et al. 2012). Aim of this study was to verify this assumption.
