The Influence of Adding Nano-tungsten Carbide on the Wear Rate and Coefficient of Friction for Chopped Fibers Composite
Year: 2026
Type: article
Abstract: Although epoxy compounds are often used in engineering and industrial environments, their poor resistance to wear in high-friction environments requires changes to their mechanical and surface properties. To improve wear properties, tungsten carbide nanoparticles WC at concentrations (1%, 1.5%, and 2%) were used to reinforce hybrid epoxy composites with chopped glass fibers (8%) and chopped sisal fibers (4%). A pin-on-disc devise was used to perform the dry wear test according to ASTM G99 guidelines. The best result was obtained with the addition of 1.5% WC compared to pure epoxy, with a 46.4% improvement in wear rate for the glass fiber-reinforced specimen with a friction coefficient of 0.20 and a 33.9% increase for the sisal fiber-reinforced specimen with a friction coefficient of 0.29
