Abstract

The mechanical properties of brake pad composites produced from powdered Pentaclethra macrophylla pod reinforced with gum Arabic resin were investigated. The pods were cleaned, air-dried, oven-dried at 110 °C to constant weight, pulverized, and sieved, after which a portion was carbonized at 950 °C. Composite formulation was carried out using a pre-impregnation technique, with the reinforcement content varied from 10 to 50 wt% at 10 wt% intervals, while other constituents were maintained constant. The composites were molded in a hot platen press using a 50 mm × 50 mm × 8 mm mold at 180 °C, a pressure of 15 MPa, and a curing time of 5 min, followed by post-curing heat treatment at 180 °C for 4 h. Mechanical characterization was performed in accordance with ASTM D785 and ASTM D6641 standards to determine hardness (Rockwell K scale) and compressive strength, respectively. The results showed that brake pads reinforced with 150 μm particle size exhibited superior mechanical performance. Maximum hardness and compressive strength values of 90.8 HRK and 84.6 N/mm2 were obtained at 30 wt% reinforcement for carbonized samples, while values of 101.2 HRK and 95.8 N/mm2 were recorded for uncarbonized samples at the same composition. These results demonstrate the suitability of Pentaclethra macrophylla pod as an alternative reinforcement material for brake pad applications.
