The continuous advancement in science and technology necessitates the development of engineering materials tailored to specific requirements and cost-effective with minimal energy consumption. Consequently, there has been a surge in research dedicated to the fabrication of composite materials. Traditionally, the inclusion of synthetic fibers like glass or carbon is a common practice to reinforce composites and impart the necessary properties. However, their slow biodegradability poses environmental concerns, driving interest in natural fibers as substitutes. Rice husk (RH), a byproduct of rice milling, stands out as one of the most abundant agricultural wastes globally. Incorporating rice husk into polymer matrices is cost-effective and offers improved mechanical properties, low density and biodegradability etc. Various surface treatment techniques like alkaline treatment, benzoylation, acetylation and silane treatment etc., are explored to improve the integration of rice husk with base polymer, thereby imparting improved mechanical properties to composites. The present article provides an extensive review of literature regarding the prospective use of rice husk as reinforcement in various polymer matrices, highlighting primarily the mechanical attributes of polymer composites. Existing literature spanning the last 20 years has been extensively explored to analyse the impact of utilizing RH on the mechanical attributes of RH-reinforced polymeric materials. Future research directions are also highlighted, emphasizing the need for further exploration and optimization of rice husk-based composites for diverse industrial applications.
