Uji keausan dan uji kekerasan pada kampas rem berbahan Pirolisis tempurung kelapa sawit dengan matriks epoxy

Abstract

This research responds to the industry's need for environmentally friendly brake linings as an alternative to asbestos brake linings. The main focus is combining palm oil shell powder with epoxy resin as the matrix. This experiment involves varying the volume fraction and pyrolysis temperature to optimize the hardness of the pyrolysis brake lining which shows the shrinkage of palm shell powder at temperatures of 400oC, 450oC and 500oC, giving results for manufacture of brake linings. Hardness testing with a durometer showed that a mixed formulation of 50% palm shell powder + 50% epoxy resin at a temperature of 400 oC gave the highest hardness (72 HD) but experienced a decrease in temperature of 500 oC (53.3 HD). Hardness test analysis according to SNI standards shows that the formulation of 50% + 50% palm shell powder and epoxy resin at a temperature of 400 oC meets SNI standards (72 HD). However, this research highlights further development to achieve optimal development in brake lining hardness, this research contributes to the development of environmentally friendly alternative brake linings with positive results in hardness tests.
