| Popis: | In this study, samples which can be used as brake pads are prepared. A mixture of 50% barite by mass, 20% glass fiber, 25% phenolic resin and 5% coke powder was prepared, and 6 samples were prepared by adding juniperus drupacea nut powder (JDNP) at 10%, 25% and 40%. The samples were produced in 3 different mixing times, 2 different compaction times, 3 different compaction temperatures and 3 different compression pressures. The effect of the compression pressure on the wear rate, hardness, density and cold friction coefficient was investigated. The wear rate ranges from 0.093.10-7 - 4.235.10-7cm3.N-1.m-1. The coefficient of cold friction ranges from 0.30 to 0.48. The density is between 1.82-2.17g/cm3. The hardness values are from 85 to 117 according to the Rockwell R scale. Wear rate and cold friction coefficient values are in accordance with TS 555 standard. It has been determined that the compressive pressure is most affected by the hardness and friction coefficient. Generally, rise of pressure reduces hardness and friction coefficient. The effect of density on JDNP ratio is opposite. |
