Performance testing of motorcycle centrifugal clutch lining made from composite wood powder, coconut fibre, and green mussel shell

Abstract

This study aims to determine the performance of a motorcycle fitted with a CVT centrifugal clutch lining made from a composite of wood powder, coconut fiber and green clam shell powder with epoxy resin as a constituent matrix. The process of making clutch lining is carried out by mixing the composite constituent materials in the form of powder. The specimens were made in two variations where clutch B was 20% wood powder, 20% coconut fibre, 10% green shell powder. Clutch C was 10% wood powder, 30% coconut fiber, and 10% green shell powder. Genuine clutch A was tested by the same method as the comparison. Meanwhile, the performance testing of automatic motorcycle was carried out by a chassis dynamometer to determine power and torque on wheels. Clutch lining with natural composite materials from a mixture of wood powder, coconut fiber, and shell powder have a greater power and torque than the genuine clutch lining. The performance of clutch B is better than C because the composition of B has 10% more wood powder which cellulose that affects the characteristics of natural fiber composites.
