Abstract
Abstract The effects of zinc, steel, aluminum, and brass materials that can be used instead of copper in brake friction composites on braking performance were investigated in this study. The specimens containing three different ratios of metallic shavings were produced by the dry mixing method. In terms of comparison, a total of 16 specimens were examined by producing the specimen containing copper at the same rates and the specimen containing no metallic chip. The weight loss, specific wear rate, and friction coefficient of the specimens were determined by the brake test results. The hardness and density tests were carried out. Thermal conductivity tests of the specimens were carried out to determine the thermal characteristic of copper. Among the metallic chips used, aluminum and steel wool were found to be good alternatives to copper.
期刊介绍：
Materials Testing is a SCI-listed English language journal dealing with all aspects of material and component testing with a special focus on transfer between laboratory research into industrial application. The journal provides first-hand information on non-destructive, destructive, optical, physical and chemical test procedures. It contains exclusive articles which are peer-reviewed applying respectively high international quality criterions.
