Abstract

Brake pads are generally manufactured using 60% asbestos. Although still widely used, asbestos is not environmentally friendly and poses serious health risks due to its carcinogenic properties, which can cause respiratory disorders when inhaled. Therefore, new environmentally safer innovations are needed, such as phenolic resin matrix composites. This study aims to analyze the effect of matrix percentage and compaction pressure on the density and hardness of phenolic resin matrix composites reinforced with aluminum, brass, silica sand, and boiler fly ash. The powder metallurgy method was applied, consisting of mixing, compaction, and sintering processes. Mixing was carried out using a horizontal ball mill with a Ball Powder Ratio (BPR) of 10:1 at 90 rpm for 4 hours. Matrix compositions of 25%, 29%, and 33% were tested, along with compaction pressures of 5100, 5400, and 5700 psi for 10 minutes. Density testing followed ASTM B962-17, and hardness testing used ASTM E110-14. The highest hardness before sintering was 154 HB, and the highest density was 1.308 g/cm³ at 5700 psi. After sintering, hardness increased to 216 HB and density to 2.120 g/cm³ at 5700 psi with 25% matrix composition.

Abstract

In general, the manufacture of brake pad components is made of 60% asbestos material, although this material is still often used, it turns out that the material is not environmentally friendly and not good for health because it contains carcinogenic substances that if inhaled by human lungs can cause respiratory disturbances. Therefore, it is necessary to develop new innovations, one of which is phenolic resin matrix composites. This study aims to determine the effect of matrix percentage and sintering temperature on the density and hardness of phenolic resin matrix composite materials combined with aluminum, brass, silica sand, and boiler fly ash. The method applied in this study is powder metallurgy, which has stages of mixing, compression, and sintering processes. The process of mixing metal reinforcing powder and fly ash boiler uses a horizontal ball mill machine with a Ball Powder Ratio (BPR) parameter of 10:1 which has a rotation speed of 90 rpm and is waited for 4 hours. Then for cold compaction, it uses 5300 Psi and waits for 10 minutes and the variations used are the percentage of matrices of 44 wt.%, 52 wt.%, and 60 wt.% and the variation in sintering temperature of 80°C, 90°C, and 100°C and in the oven for 10 minutes. The test was carried out using the ASTM B962-17 standard for density test while the hardness test used the ASTM E110-14 approach using a portable hardness test device. Hardness testing with the highest value of 102 HB with a matrix percentage of 60 wt.% with a pressure of 5300 Psi and the highest density value of 1.404 g/cm3 with a compaction pressure of 5300 Psi before the sintering treatment. After sintering treatment, the highest hardness result was 147 HB with a matrix percentage of 60 wt.% with a temperature of 50°C and the highest density value of 1,505 g/cm3 with a temperature of 50°C with a holding time of 10 minutes each.
