Rice straw and rice husk composites have been found to exhibit different mechanical properties. An increase in rice straw loading decreases the tensile strength in a manner similar to that found in other natural fiber composites, as high fiberloading results in fiber agglomeration. At a given fiber loading, increased rice straw particle size leads to increased tensile strength of the composite. Rice straw finds its applications in making particleboards and fiberboards, and car roofs and doors, whereas rice straw is mostly used in cementitious composites.
