Uji Koefisien Gesek Kampas Rem Dari Serbuk Serabut Kelapa Hasil Dari Variasi Waktu Penahanan Sintering

Abstract

Number of good vehicles of wheel two and wheel four now is estimated reachs number tens of million units. More than anything else, replacement of brake pad brake in segment of this vehicle one year can more than twice. So among industry brake pad raw material material problem still depend on material or expensive import material. One of solution to get the price of product which more competitive is by the way of doing material engineering with aim to depress price, by the way of substitution and selection “ raw material” what has coefficient to fiddle height and has competitive price. In this research done expansion of sintered technique with various detention time of material applied by coconut fiber powder, phonelic resin, and brass powder. Originally coconut fiber waste is refined with blender then is sieved with mesh 30. Coconut fiber powder mixed with brass powder, and ponelich resin with composition applied by coconut fiber powder 28 grams, brass 084 grams and resin 56 grams by using blender. Brake pad is made with printed at compaction machine and heated at temperature 150oC during 90, 120 and 150 minutes. Hereinafter brake pad is hardness test it and characteristic test so that knowable brake pad performance. Result of hardness of Brinell specimen 21,88 and coefficient fiddles 2 for brake pad factory brake while hardiness 18,82, 18,19, and 20,46 and coefficient fiddles 0,5, 0,4 and 2. for prototype with sinter temperature 150oC during 90, 120 and 150 minutes. Keywords: brake pad, sintering, recycle waste, Coconut fiber.
