Abstract

Innovations in making non-asbestos brake linings are increasingly being developed, asbestos materials which are less friendly to the environment and health are the main factors. This research utilizes recycled aluminum as a matrix and boiler fly-ash and silica sand as reinforcement. The aim of this research process is to determine the differences in variations in hot compaction pressure and powder volume percentage on shrinkage values and friction coefficients. The method used is the powder metallurgy method which includes mechanical alloying, hot compaction pressing and sintering. Mechanical Alloying is carried out using a ball mill machine with Ball Parameter-weight of Ratio (BPR) parameters of 10:1, rotational speed of 90 rpm, holding time of 6 hours with variations in the matrix percentage of 86%, 90%, 94% and the results of the mechanical alloying  will be weighed in variations, namely 25 gr. , 35 gr, and 45 gr. ASTM B962-17 density test and ASTM G99-05 coefficient of friction or wear test. The results obtained were the highest density value of 2.055 gr/cm3 with a reinforcement percentage of 94% compaction of 5600 Psi. The lowest density value is 1.848 gr/cm3 with a reinforcement percentage of 86% compaction of 5600 Psi. The friction coefficient test value is 0.147 gr with a reinforcement percentage of 86%, the powder weight is 45 gr. The lowest value of the friction coefficient test was 0.020 gr using a reinforcement percentage of 94% and a powder weight of 35 gr.

Abstract

This study aims to analyze the effect of compaction pressure variation and matrix percentage on the mechanical and physical properties of phenolic resin–metal powder–RHA hybrid composites as an alternative non-asbestos brake pad material. The composite manufacturing process was carried out using the powder metallurgy method, which included milling, compaction at pressures of 5000, 5300, and 5600 psi, and sintering at a temperature of 130°C for 10 minutes. The tests included Brinell hardness based on ASTM E110-14 and density using the Archimedes method according to ASTM B962-17. The results showed that an increase in compaction pressure had a significant effect on increasing both hardness and density. Optimal conditions were obtained at a pressure of 5600 psi and a matrix fraction of 35%, resulting in a hardness of 103.77 HB and a density of 1.54 g/cm³. These values meet the standards for commercial brake pad materials, namely a hardness of 65–105 HB and a density of 1.5–2.5 g/cm³. Thus, the developed hybrid composite has the potential to be used as an environmentally friendly brake pad material to replace asbestos. Further research is recommended to examine the tribological properties and wear resistance to ensure the performance of the material under actual working conditions.
