(2) Under dynamic loading, Young’s modulus, tensile strength, maximum strain and toughness of the fabric and yarn increase with increasing strain rate over the strain rate range from 20 to 170 s-1. However, based on the current results, it is not clear what the effect of the gage length is on the dynamic properties. References [1] B. Farsi Dooraki, J. A.Nemes, M.
