Pengaruh Penambahan Fraksi Massa Tempurung Kelapa Pada Pembuatan Spesimen Uji Kampas Rem Berbahan Dasar Cangkang Kerang Bulu, Serbuk Besi dan Resin Epoxy Terhadap Nilai Kekerasan dan Laju Keausan

Abstract

This research aims to determine the effect of adding coconut shell on hardness and wear rate. The materials used in this research were coconut shells, clam shells, iron powder (Fe) and resin. The process of making brake pads is through a metallurgical process, namely the process of mixing the powder until it is evenly distributed. The evently distributed powder is then put into a mold and compacted with a load of 2 tons for 15 minutes and sintered at a temperature of 175℃ for 15 minutes. Testing includes hardnesstests and wear tests. The best hardness and wear test results were found in composition Awith results of 28,02 BHN, 8,8 x 10−6(gr/mm2). The friction coefficient tests carried out have different values for each composition. Composition A has a friction coefficient value of 0,1263, composition B has a friction coefficient value of 0,1428 and composition C has a friction coefficient value of 0,1368
