Ultra High Molecular Weight

Ultra-high molecular weight polyethylene (UHMWPE) fiber reinforced plastic (UFRP) is an integral part of hard body armor. The intensive study on the material characterization of UFRP can help to understanding the bulletproof mechanism and behind-armor blunt trauma (BABT) well, and thus improve the performance of body armor. The research presented in this paper represents an effort to characterize the properties of UFRP under quasi-static and ballistic loading. The tensile behavior along the fiber direction and through thickness compressive behavior were obtained using an universal material testing machine. Experiments show that the tensile strength and compressive strength of UFRP are approximately 500MPa and 650MPa, respectively. The through thickness shear strength of UFRP was also obtained according to the punch-shear testing, and a set of special clamp was used to clamp the samples. The composite has been found to have a low shear strength. The UFRP was impacted by a 4.8mm diameter spherical fragment with velocity 694m/s~920m/s, to study the ballistic performance. And the height and radius of the deformed conical region on the back face of UFRP were captured using high-speed photography technique. Results show the maximum transient height of the cone is about 3 to 4 times greater than the final height of the cone, and the radius of the cone reaches to 59±7.4mm. The ballistic limit of the 11mm thick UFRP is approximately 800m/s.

Purpose To overcome the problem of inferior through-the-thickness mechanical properties displayed by armor-grade composites based on 2-D reinforcement architectures, armor-grade composites based on 3D fiber-reinforcement architectures have recently been investigated experimentally. Design/methodology/approach The subject of the present work is armor-grade composite materials reinforced using ultra-high-molecular-weight polyethylene fibers and having four (two 2D and two 3D) prototypical architectures, as well as the derivation of the corresponding material models. The effect of the reinforcement architecture is accounted for by constructing the appropriate unit cells (within which the constituent materials and their morphologies are represented explicitly) and subjecting them to a series of virtual mechanical tests. The results obtained are used within a post-processing analysis to derive and parameterize the corresponding homogenized-material models. One of these models (specifically, the one for 0°/90° cross-collimated fiber architecture) was directly validated by comparing its predictions with the experimental counterparts. The other models are validated by examining their physical soundness and details of their predictions. Lastly, the models are integrated as user-material subroutines, and linked with a commercial finite-element package, in order to carry out a transient non-linear dynamics analysis of ballistic transverse impact of armor-grade composite-material panels with different reinforcement architectures. Findings It is found that the reinforcement architecture plays a critical role in the overall ballistic limit of the armor panel, as well as in its structural and damage/failure response. Originality/value To the authors’ knowledge, the present work is the first reported attempt to assess, computationally, the utility and effectiveness of 3D fiber-reinforcement architectures for ballistic impact applications.
