Pengaruh Variasi Komposisi Serbuk Phenolic Resin Terhadap Kekerasan dan Kekuatan Tekan Kampas Rem Berbahan Dasar Serabut Kelapa

Abstract

Brake pad is an essential parts in the vehicles. Nowadays we can see the increasity of vehicle amount as far as the growth up economic condition in the society. The main vehicles component parts is a brake pad, this parts must have a good attention from the government to protect consumers and decreasing the accident factor on the street. Considering the opportunity of brake pad with non asbestos type in any factors knows it’s a time to start develop and sozialize to decreasing the level of using for stuff which asbes as a basic component which of have a negative impact for the consumers it self. And a coconut fiber can be use as an alternative to subtitute the asbes material. The main part of this research is a coconut fiber specificly a cocodust which of mixed by phenolic resin and brass by variating phenolic resin composition of percentage with 100 KN compression, 150oC temperatures and 120 minutes holding time. A specimen had a hardness and pressure tested to know the character of mechanism. The hardness test with Brinell method and compressive test with Tarno Grocki compressive test machine. Theres a different between the result of phenolic resin composition of variation. The phenolic resin is 10% and 15% averagely not too hard rather than a composition with 20% phenolic resin percentation. Meanwhile the higher compressive stress number could get from the result of compressive test on specimen with 20% phenolic resin composition which is 110.938 N/mm2 and the lower result of 10% phenolic resin composition specimen is 71.875 N/mm2. Key words : Brake pad, coconut fiber, phenolic resin, hardness test, compressive test
