Abstract
Natural materials have been represented as an interesting field of study in composites. Using such materials as reinforcement for polymer matrix composites has been focused on. In this study, samples made from walnut shells powder (WSP) mixed with polypropylene by 30%, 40%, and 50% weight fractions have been tested for mechanical and Tribological properties. Tensile and short beam tests have shown decreasing in the ultimate stress as the powder fraction was increased. Modulus of elasticity was noticed to be decreasing as the percentage elongation was increased. However, wear results showed enhancement in the specific wear rate with increasing the powder fraction. Even more, it was noticed that increasing the normal force has led to minimizing material losses. Similar to the wear, the hardness test showed improvement by increasing the powder percentage.
