The objective of this research was to evaluate the impact of rice husk particle size on the performance of resin-based brake pads. In the experiment, rice husk particles used were measuring 79, 89, 125, and 250 μm. Rice husks are mixed in a resin mixture containing Bisphenol A-epichlorohydrin and cycloaliphatic amines to make brake pads. Then the brake pads were analysed to obtain the compressive strength, the puncture strength, the wear rate, the mass loss, the coefficient of friction, and the physical microstructure using a microscope. Rice husks are highly preferred because they tend to contain cellulose, lignin, pentosan, and silica, making them suitable as friction materials with similar properties to ceramics. The experiment result showed that brake pads with a combination of resin mixtures at a small particle size of rice husks experienced an increase in compressive strength, puncture strength, and density. The analysis showed that the maximum values for the compressive strength of the brake pads supported by rice husk particles of 79, 89, 125, and 250 μm are 0.110; 0.109; 0.105; and 0.109 MPa, respectively. The large rice husk particles formed rough surfaces and had porous structures, reducing the rate of mass loss and increasing the frictional properties (ie the wear rate and the coefficient of friction). The coefficient values of friction of the brake pad using rice husk particles of 79, 89, 125, and 250 μm are 0.000397; 0.000392; 0.000381; and 0.000393, respectively. Particle size factors affect the interfacial bonding, pore size, mechanical properties, thermal softening, and reinforcement properties of brake pads. This research utilizes rice …
