In the quest for sustainable and high-performing brake materials, a team of researchers from Universitas Sultan Ageng Tirtayasa in Cilegon, Indonesia, has made a significant stride. Led by Sunardi Sunardi, the team has developed a composite brake pad using natural, environmentally friendly materials that maintain their performance even after prolonged exposure to engine oil. This breakthrough could have substantial implications for the automotive and energy sectors, particularly in the development of green technologies.
The composite brake pad, composed of a blend of phenolic resin, eggshell particles, bamboo fibre, bamboo particles, alumina powder, zinc powder, and graphite powder, underwent a rigorous manufacturing process. The samples were immersed in engine oil for varying durations, and the results were promising. “The composites made from calcined eggshell and bamboo particles exhibited remarkable stability and performance,” said Sunardi. The brake pads maintained a coefficient of friction between 0.33 and 0.36, a friction stability coefficient ranging from 71.59 to 79.19, and a flexural strength between 7.23 and 8.25 MPa.
The wear rate experienced a slight increase, but it was minimal, measuring between 4.75 and 6.64 mm³/m. The flexural modulus was found to be between 4.44 and 5.49 GPa, while the hardness ranged from 43.35 to 91.05 HRR. These results indicate that the composite brake pads can withstand the harsh conditions of engine oil exposure without significant degradation in performance.
The use of natural materials in brake pads is not only environmentally friendly but also cost-effective. The automotive industry, which is increasingly focused on sustainability, could benefit significantly from this research. “This study opens up new possibilities for the development of green brake materials,” Sunardi noted. “It paves the way for more sustainable and efficient braking systems in the future.”
The findings of this research were published in the journal *Tribology and Materials*, which translates to “Friction and Materials” in English. This study is a testament to the potential of natural materials in enhancing the performance and sustainability of automotive components. As the world moves towards greener technologies, such innovations will be crucial in shaping the future of the energy and automotive sectors.
The implications of this research extend beyond the automotive industry. The energy sector, which relies heavily on efficient and sustainable technologies, could also benefit from the development of green brake materials. As Sunardi pointed out, “The use of natural materials in brake pads not only reduces environmental impact but also enhances performance and durability.”
In conclusion, the research led by Sunardi Sunardi from Universitas Sultan Ageng Tirtayasa represents a significant step forward in the development of sustainable and high-performing brake materials. The findings of this study could have far-reaching implications for the automotive and energy sectors, paving the way for a greener and more efficient future. As the world continues to seek sustainable solutions, such innovations will be instrumental in driving progress and shaping the future of technology.
