This work is aimed to valorize the agricultural waste based on the wheat husk (WH) by its incorporation as the reinforcing filler in the polyvinyl chloride (PVC) matrix. To improve interfacial adhesion, the fiber is chemically treated with acetic anhydride (AA). Various composite samples made of PVC and WH fibers at different loading rates, i.e., 10, 20, and 30 wt% are prepared. The transmission Fourier transform infrared spectroscopy IRTF results revealed that the reaction of acetylation has occurred. The results indicate a reduction in the mechanical properties according to the load factor as well as an improvement for the treated composites compared to the untreated composites. There is a reduction in the modulus according to the load factor for PVC/WHAA composites compared to the PVC/WH for both the 20 and 30 wt% formulations.
