Mechanical properties of rice husk (Oryza sativa) reinforced low density polyethylene composites for industrial injection moulded parts Available to Purchase

Injection moulding is one of the most widely used processes in manufacturing plastic products, which has developed into a mature technology. Injection moulding is greatly preferred in manufacturing industry because it can produce complex-shaped plastic parts with good dimensional accuracy in very short cycle times. This article is concerned with the tensile properties of low-density polyethylene (LDPE) reinforced with alkaline treated rice husk (RH) specifically for injection moulded parts. In this study, the RH/LDPE composites with different loadings of 5, 10, and 15 wt.% treated RH were feed into injection moulding machine and the moulded parts were tested using conventional universal testing machine. The results showed that the tensile and flexural properties of the RH/LDPE composites were strongly affected by the filler loadings. Furthermore, all the tensile and flexural properties of the RH/LDPE composites showed increasing trend as the filler loading increased, up to 15 wt.% treated RH.
