Abstract
Experimental investigations on warp-knitted and plain weave carbon fabric composites were made under quasi-static and dynamic strain rates, which mainly focused on the effect of strain rate on the tensile and compressive strength of the composite. The strain rate was 0.5Â sâ1 for quasi-static tests performed on a universal testing machine, whereas it ranged from approximately 200Â sâ1 to 2300Â sâ1 for the dynamic testing. The test results show that the tensile strength increased with increasing strain rate for both types of fabrics, whereas the effect of strain rate was negligible for the compressive strength. Also, the failure mechanism was characterized by examining the fracture surfaces using optical and scanning electron microscopy (SEM).
