Dynamic Behavior of Aramid and UHMWPE Composites Using Split Hopkinson Pressure Bar
In this paper, high-strain-rate compression properties of aramid and UHMWPE composites in the out of-plane direction are tested at room temperature on a Split Hopkinson Pressure Bar apparatus. Tests were conducted on composites reinforced with woven or UD fabrics made from aramid or UHMWPE as well as on composites reinforced with hybrid reinforcement. The strain rate is varied in the tests by changing the projectile shooting pressure. Four different pressures; 2, 4, 6 and 8 bar were selected to change the strain rate. Stress-strain and energy absorption behaviour of eight type of samples were noted. Hybrid samples showed better performance in comparison to other samples.
