Investigation into mechanical & tribological performance of kenaf fibre particle reinforced composite

Abstract

In this current research, the mechanical, physical and tribological properties of kenaf fibre particle reinforced epoxy (KPafRE) composite was investigated. Randomly distributed kenaf fibre particles were used as reinforcement, with fibre particle loading up to 20%wt. Five mechanical tests were conducted: tensile, compression, flexural, hardness and impact tests, also an additional water absorption test. For tribology investigation, dry sliding test was conducted on a Pin on Disk (POD) machine under 5–20 N applied load at 2.8 m/s, for 6.72 km sliding distance. The results from these tests were compared with Neat Epoxy (NE). It was found that KPafRE composite showed improved mechanical properties compared to NE. The results also suggest that 15%wt. KPafRE composite is the optimum fibre particle loading condition. Applications for this composite would include for construction industry for parts such as sliding door and window panels, also hinges (replacing expensive aluminum ones currently in use). In the automotive industry, the composite could replace plastic parts currently being used in door linkages, dashboard or door aesthetic piece, also bearing or bushes.
