Experimental investigations on the in-plane dynamic compressive behavior and upper limit of constant strain rate for 2D twill weave carbon fiber reinforced composite

The in-plane dynamic compressive behavior of a 2D twill weave carbon fiber reinforced composite was investigated using the split Hopkinson pressure bar (SHPB) apparatus. Constant strain rate loading was achieved with the adoption of pulse shapers within the experiments. A non-dimensional parameter was adopted to verify the stress equilibrium state of the specimens, which ensured the effectiveness of the experimental results. The upper limit of...
