In this study, the change of mechanical properties by adding iron scales of different sizes into polypropylene (PP) was investigated. The iron scale was obtained from a steel production plant and adjusted to 30, 50, 90, 120, and 150 µm grain sizes. These iron scales were then added to the polymer material at a rate of 5% by weight. Wear and tensile strength tests were applied to the samples, which were formed in two different types. According to the results obtained, the wear and tensile strength of polymer material in all grain sizes were improved with an added iron scale. It was observed that the wear resistance of the composite material formed with the addition of fine-grained reinforcing element was the highest. Although grain size increased with increasing tensile strength, wear resistance did not increase. Besides, the friction coefficient was measured to be lower at increasing load. While the effective wear mechanism in pure polymer material is plastic deformation, this wear mechanism has not been found in composite materials with different grain sizes. In this study, it has been shown that iron scales have a positive effect on the mechanical properties of polymer composites.

在这项研究中，研究了通过将不同尺寸的铁皮添加到聚丙烯（PP）中来改变机械性能。铁鳞是从钢铁生产厂获得的，并调整为30、50、90、120和150 µm的晶粒度。然后将这些铁鳞以5重量％的比例添加到聚合物材料中。对样品进行了磨损和拉伸强度测试，这些样品以两种不同的类型形成。根据获得的结果，通过添加铁鳞改善了聚合物材料在所有晶粒尺寸下的耐磨性和拉伸强度。观察到，添加了细粒增强元素的复合材料的耐磨性最高。尽管晶粒尺寸随着拉伸强度的增加而增加，但是耐磨性并未增加。除了，在增加的载荷下测得的摩擦系数较低。尽管纯聚合物材料的有效磨损机理是塑性变形，但在具有不同晶粒尺寸的复合材料中尚未发现这种磨损机理。在这项研究中，已表明铁鳞对聚合物复合材料的机械性能具有积极影响。
