The effect of the content of microscale natural pistachio shell particles on the mechanical properties of polyester matrix composites was experimentally investigated. The pistachio shell particle contents were 0, 5, 10, 15, 20, and 25 wt%. Tensile, flexural, and Charpy impact tests were carried out on molded composite specimens according to the ISO 179/92 standard. Good dispersion of pistachio shell particles in polymer matrix was observed using SEM micrographs. The highest tensile strength, flexural strength, and impact strength were obtained at a pistachio shell particle content of 10, 5, and 5 wt%, respectively.
