Ultra High Molecular Weight

A great deal of research and development work has been recently conducted on natural fiber-reinforced polymer matrix composite for its abundancy, low density, excellent damping characteristic, and good mechanical properties. However, the low strength of natural fiber composite has limited its use to only low stress applications. The purpose of this work is to develop a natural fiber hybrid material with both enhanced strength and failure strain using a novel approach and study the effect of the processing temperature on its microstructure and performance. High-strength ultra-high molecular weight polyethylene fabrics are co-molded onto the surfaces of a kenaf fiber high-density polyethylene-based composite material by single-step compression molding. The status of the ultra-high molecular weight polyethylene fabrics at different processing temperatures is investigated using microscopic analysis. The tensile strength and impact strength of the hybrid material are evaluated. It is found that its tensile strength is increased by more than 90% with only 8% ultra-high molecular weight polyethylene fiber reinforcement added and its low density is maintained.

Ultra High Molecular Weight

AbstractColloid composition based on the nanosized carbon powder, dispersed in complex mineral solvent, was elaborated. It was found that the composition can be used both as surface coating and as filler for an ultra-high molecular weight polyethylene matrix. A study of electromagnetic wave absorption showed that the coatings and composites thus obtained possess high microwave protection properties. Wave absorption of a coating 50 μm thick varies from −5 to −25 dB depending on frequency. A study of polymer composites filled with colloid composition, showed that increase in the filler content leads to the transition from chaotically dispersed to the oriented distribution of colloid composition particles in the polymer matrix. Tensile test showed that the polymer filled with colloid composition retains the mechanical properties close to those of pure ultra-high molecular weight polyethylene (UHMWPE). Microwave absorption gradually increases with increasing filler content in UHMWPE-based composites.
