Insights into the Role of Natural Fibers in Brake Pad Composite Development
摘要
Over the past few years, there has been an increasing focus on integrating eco-friendly materials into automotive parts especially brake pads as awareness of the environmental and health risks linked to traditional friction materials continues to rise. Natural fibers have emerged as promising alternatives to mineral and metal-based substances, offering eco-friendly benefits and reduced toxicity. Despite their potential, the adoption of natural fiber composites in brake pad applications faces notable challenges, primarily related to their tribological performance, including frictional stability and thermal conductivity. Traditional brake pads initially relied on asbestos, later replaced by copper-based materials, and eventually evolved into synthetic friction composites. However, recent research has identified natural sources such as banana peels, palm kernels, and palm slag as viable reinforcement options. This study aims to investigate the characteristics of natural fiber composites and assess their potential for application in brake pad systems, with a particular emphasis on their mechanical, thermal, and tribological performance. The methodology involves analyzing the design and fabrication of brake pads using natural composites, assessing the impact of additional fillers and surface treatments on fiber performance, and exploring hybrid reinforcement strategies to enhance material characteristics. Key findings indicate that while natural composites show significant promise, their performance can be substantially improved through material optimization and hybridization techniques. These enhancements contribute to better wear resistance, improved frictional behavior, and greater thermal stability. The implications of this research suggest that with continued innovation and experimental validation, natural fiber brake pads could become a viable and sustainable solution for future automotive applications.
