Mechanisms of the penetration of ultra-high molecular weight polyethylene composite beams

A number of mechanisms have been proposed for the penetration of laminates comprising ultra-high molecular weight polyethylene (UHMWPE) fibres in a polymeric matrix. Two-dimensional ballistic experiments are conducted in order to directly observe the transient deformation and failure processes occurring immediately under the projectile via high-speed photography. Two sets of experiments were co...

Synthesis and Tribological Behavior of Ultra High Molecular Weight Polyethylene (UHMWPE)-Lignin Composites

In this paper, we report the synthesis and characterization of ultra-high molecular weight polyethylene (UHMWPE)-lignin composites. During this study four different compositions, namely UHMWPE, UHMWPE-13 wt. % lignin, UHMWPE-25 wt. % lignin and UHMWPE-42.5 wt. % lignin were fabricated by hot pressing. Detailed microstructural studies by scanning electron microscopy (SEM) showed that UHMWPE and ...

The compressive response of ultra-high molecular weight polyethylene fibres and composites

Measurements are reported for the compressive response of ultra-high molecular weight polyethylene (UHMWPE) fibres and laminated composites loaded along the fibre direction. The compressive strength of the fibres was measured by both recoil tests and knot (or bend) tests. The strength of the fibres is governed by micro-kinking of the fibrils within the fibres. The recoil tests suggest that this...
