Abstract
Rice husk (RH)–glass fiber (GF) hybrid polyester composites have been produced. Tensile, flexural, impact, and dimensional properties of the composites have been investigated. From the results, it was observed that GF imparted higher tensile, flexural, and impact properties. The presence of RH in the matrix produced composites with comparable tensile, flexural, and impact properties especially in the middle range of RH:GF ratios. Longer GF had a profound effect on the strength and toughness, while the shorter GF contributed the modulus of the composites. The incorporation of RH in the composites resulted in an increase in water absorption and thickness swelling. Overall, the study shows that RH together with GF produced composites with acceptable properties.
