The Effect of Loading Rate on the Tensile Behavior of Single Zylon Fiber
The commercially available ZylonTM single fiber has been investigated to understand the effect of strain rate on the tensile response. Experiments were conducted on single Zylon fibers across a range of strain rates ranging from 0.001/s to ~1000/s. The low rate uniaxial tensile experiments were performed using a Bose TestBenchTM system. The high rate dynamic tensile experiments were performed using a modified Kolsky Bar setup. This paper discusses the experimental setup and presents the effect of strain rate on the tensile deformation and failure behavior of this single fiber. These experimental data will be used to develop continuum and micro-mechanics based fabric models and computational simulation methodologies for impact of these fabrics by projectiles; this will allow engineers to better understand the impact behavior of composite structures created with fabrics made of this fiber.
