摘要

This investigation aimed to produce Non-Asbestos Organic (NAO) brake friction composite materials by combining sisal fiber, jute fiber, and sisal-jute fibers along with additional fillers and additives. The material was fabricated using compression molding and subjected to compression strength, hardness, and wear testing. Results showed that increasing fiber weight percentage enhances hardness and compression strength, with sisal fiber, jute fiber and hybrid composites exhibiting 21%, 11.6%, and 16.65% enhanced compression strength, correspondingly. Wear loss decreased proportionally with fiber weight percentage, although sisal fiber exhibited maximum wear loss. Optimization revealed that reinforcement percentage is the most significant factor influencing brake performance. The developed composites are suitable for braking system components, such as brake pads.
