Pengaruh Variasi Komposisi Serbuk Phenolic Resin Terhadap Keausan Kampas Rem Berbahan Dasar Serabut Kelapa

Abstract

Commonly brake pad product is made from asbestos material, but this asbestos material have bad impact to human health, so it is necessary to find the solution to replace brake pad material to find the solution to replace brake pad material with non-asbestos. In the nowdays economy recession, by choosing and using brake pad, user consider durable aspect as most important han other aspect such as health and braking quality. The research aim to examine and understand durability aftermarket brake pad with asbestos material and non-asbestos prototype brake pad coconut fiber material. In this research, coconut fiber material is used, especially the fiber’s dust. Coconut fiber raw material is blended with blender, then being mesh 30 to get same powder size. After that, its blended with brass and phenolic resin. To know the effect of the phenolic resin to the wear of brake pad, so the composition of phenolic resin is variated 10%, 15%, and 20%. After that its compacted with pressing 100 KN and its sintered to 150 °C temperature, and holding time for 2 hours. Wear test held by 1,5 Kg, 2,5 Kg, and 3,5 Kg load during 4 x 60 minutes, so that it can be seen the brake pad characteristic for each each composition. The result of the test for 1,5 Kg load, wear rate for aftermarket brake pad 0.000683 mm3 /m, for K1, K2, and K3 are 0.005289 mm3 /m, 0.004855 mm3 /m, 0.003701 mm3 /m. the bigger percentage of phenolic resin composition can cause the smaller wear rate value. Keyword : brake pad, coconut fiber, phenolic resin, wear rate.
