Abstract

The use of composite materials in brake pads is becoming increasingly popular due to their high-performance characteristics, including good thermal stability, high wear resistance, and low noise generation. However, the development of new composite materials that offer even better performance is still an ongoing research area. In this study, the composite was made by hand layup method using epoxy resin as matrix material, with rice husk, Al2O3, and Fe2O3 as reinforcing materials. The composition of the composites was varied by changing the percentage of the reinforcement materials. The composites were then subjected to several characterization tests, including density, hardness, flexural strength, thermal analysis, Scanning Electron Microscopy (SEM), TGA/DSC, and wear testing. The test results showed that additional reinforcement materials to the epoxy resin matrix improved the mechanical properties of the composites. Overall, the study demonstrates that a hand layup method is a viable approach for preparing brake pad composite materials and that the addition of rice husk, Al2O3, and Fe2O3 can improve the mechanical properties of the composites. The best properties produced in this research were found in one of the specimens which used epoxy, rice husk, Al2O3, and Fe2O3 with a composition of 50 wt.%, 20 wt.%, 15 wt.%, and 15 wt.%. However, the addition of rice husk also provides wear resistance and thermal stability. This study contributes to the Sustainable Development Goals (SDGs) by advancing innovation, promoting sustainability, and reducing emissions in automotive industry applications.

Abstract

Developing epoxy-based composites reinforced with natural materials has become a significant concern in supporting friction materials and sustainable automotive industries. Coco peat and coco shell charcoal are coconut wastes that have the potential as natural fillers to support the mechanical properties of friction material composites while supporting the reduction of biomass waste. This study aims to evaluate the effect of weight fraction variation of coco peat and coco shell charcoal on composite mechanical and thermal properties. Specimens were prepared using the hand lay-up method with 5%, 10%, and 15% filler weight fractions. Mechanical tests were conducted, including tensile test, bending test, Rockwell hardness, and Charpy impact. Results show that the addition of 5% coco peat increased the tensile strength to 28.36 MPa and impact strength to 123.33 J/m², while coco shell charcoal at 10% recorded the highest flexural strength of 36.10 MPa and hardness of 93.66 HRB. However, increasing the filler concentration caused a decrease in tensile and impact strength due to the formation of voids, agglomeration, and micro-cracks. These findings confirm that coco peat is effective for tensile and impact strengthening at low fractions. In contrast, coco shell charcoal improves flexural strength and produces higher hardness values than the commercial brake pad product (59.59-66.90 HRB). Furthermore, the composite with 5% coco shell charcoal showed good thermal stability with a final residue value of 3.83%. Further studies can focus on surface modification of fillers, hybrid composites, and evaluation of tribological properties and the environment to promote applications in the automotive industry sector.
