Abstract

Ballistic impact onto fiber-based personnel protection armor systems induce multiaxial loading in the affected impact zone that includes axial tension, axial compression, transverse compression and transverse shear. The influence of the transverse compression response of ballistic fibers at high rates of loading is not well understood. In this study, high strain rate transverse compression response of aramid Kevlar KM2 and ultra-high molecular weight polyethylene (UHMWPE) Dyneema SK76 single fibers are investigated. Micron scale single fibers are transversely compressed at high loading rates in a small diameter Kolsky bar with optical interferometry to measure strains in the bars. The fibers exhibit a nonlinear inelastic behavior in transverse compression. Comparison of high rate and quasi-static response indicate a smaller contact area growth and a stiffer material response at higher rates of loading for both types of fibers.
