In order to analyses the reinforcing effect of walnut filler, the present article deals with the variable walnut filler loading in chopped glass fiber-polyester composite. Cleaning and removing of dirt from walnut was performed before reinforcing. Grinding of walnut shell was carried out in the grinder to transform it in required size. Hand lay-up method was employed in fabricating the composite samples The composite samples were characterized for Vickers hardness and specific wear. The obtained results were fruitful not only in increasing the hardness but also reducing the specific wear rate. The optimized walnut filler loading was obtained at 15 wt. %.
