Ultra High Molecular Weight

The paper at hand presents an investigation of the tensile behavior of high-strength, strain-hardening cement-based composites (HS-SHCC), reinforced with a single layer of continuous, two-dimensional textile made of ultra-high molecular weight polyethylene (UHMWPE). Uniaxial tension tests were performed on the bare UHMWPE textiles, on plain HS-SHCC, and on the hybrid fiber-reinforced composites. The bond properties between the textile yarns and the surrounding composite were investigated in single-yarn pullout experiments. In order to assess the influence of bond strength between the yarn and HS-SHCC on the tensile behavior of the composites with hybrid fiber reinforcement, the textile samples were analyzed both with, and without, an additional coating of epoxy resin and sand. Compared to the composites reinforced with carbon yarns in previous studies by the authors, the high elongation capacity of the UHMWPE textile established the higher strain capacity of the hybrid fiber-reinforced composites, and showed superior energy absorption capacity up to failure. The UHMWPE textile limited the average crack width in comparison with that of plain HS-SHCC, but led to slightly larger crack widths when compared to equivalent composites reinforced with carbon textile, the reason for which was traced back to the lower Young’s modulus and the higher elongation capacity of the polymer textile.

Ultra High Molecular Weight

Some dynamic compressive tests about Ultra-High Molecular Weight Polyethylene Fiber-reinforced laminated Composites have been done using SHPB experimental system．The stress-strain curves of UHMWPE Fiber-reinforced Composites of three different laminated angles (0/90°, 0/90/45/-45°, 0/90/30/-60/60/-30°) are obtained at higher strain rates and their dynamic mechanical properties are also investigated at the same time．Based on all the stress-strain curves obtained, the characteristics of energy absorption of UHMWPE fiber angle-plied composites are analyzed and discussed．It is found that laminated angle has made little effect on the dynamic energy absorption of composites at higher strain rates．In addition，delamination and compaction in the thickness direction constitute the main dynamic failure mechanisms, which are studied by means of image analyses for the specimens after compression.

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.
