Interlaminar shear characterization of ultra-high molecular weight polyethylene (UHMWPE) composite laminates

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 ...

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...

Aging effect on the tribological behavior of a Novel 3Y-TZP/Nb Biocomposite against Ultra High Molecular Weight Polyethylene (UHMWPE)

The aim of this study was to evaluate the friction and wear behavior of ultra high molecular weight polyethylene (UHMWPE) against 3Y-TZP and a novel 3Y-TZP/niobium (Nb) biocomposite. The ceramic and the biocomposite materials were subjected to an accelerated aging process to evaluate the changes in the tribological behavior after this treatment. To carry out the tribological tests, a reciprocat...
