Analisis kekerasan material alternatif kampas kopling berbahan komposit resin diperkuat limbah kaca dan serat alami

Abstract

Clutch discs in motor vehicles are commonly made from asbestos, a material that is hazardous and environmentally unfriendly. Therefore, there is a need for more eco-friendly alternatives by utilizing waste materials, such as glass waste and natural fibers. This study aims to evaluate the use of resin-based composites reinforced with natural fibers and glass waste as alternative materials for clutch discs. We tested various combinations of resin, natural fibers (coconut fiber, coir fiber), and glass powder to determine which composite offers the best hardness properties. Samples were divided into two groups with different compositions and tested for hardness using the Rockwell method. The results showed that the composite with a composition of 20% glass waste powder, 20% coir fiber, 20% glass powder, and 40% resin achieved the highest hardness, with a Rockwell hardness value of 70 HRB, which closely approaches the standard hardness for automatic transmission clutch discs.This research reveals the significant potential of using natural fibers and glass waste as sustainable and high-performance composite materials. The findings contribute to the development of green composite materials and offer a more environmentally friendly alternative in the automotive industry.
