Abstract

This study reports on the development of polyester composites reinforced with pistachio shell powder (PSP), an eco-friendly filler sourced from agricultural wastes. The PSP was processed through grinding and sieving before being added to the polyester resin in different weight fractions, ranging from 0 % to 5 %, using the hand lay-up route. These composites were then tested to evaluate their mechanical strength and tribological performance, particularly for applications requiring high wear resistance and notable frictional stability. A pin-on-disc apparatus was employed to assess the abrasive wear response under various applied loads and sliding speeds. Results indicated a notable improvement in the mechanical and tribological properties of the polyester composites due to PSP inclusion. Surface morphology analysis of the worn regions showed the presence of cracks and grooves at lower filler contents, while higher filler content led to increased formation of wear debris from the material.
