Pengaruh Serat Tanaman Sansevieria Dan Fiberglass Dengan Besar Butiran Alumunium Silikon (Al-Si) Mesh 70, 80, 100 Terhadap Nilai Pengujian Kekerasan, Keausan, Dan Koefisien Gesek Pada Kampas Rem

In this study, researchers wanted to make and examine samples of motorcycle brake linings using environmentally friendly composite materials using natural materials namely sansevieria plant fibers with a variety of mesh grains to determine the value of hardness, wear and friction coefficient of brake lining. The materials used in this study were sansevieria plant fibers, calcium carbonate, barium sulfate, polyester resin, fiberglass, and aluminum silicon (Al-Si) with mesh variations of 70.80 and 100. Then the hardness was tested using a Durometer with ASTM D2240 standard, and tested for friction with a load of 16 kg for 3 hours with dry test, wet test, salt water test, brake oil test, and oil test, and calculated the wear and coefficient of friction. From the results of the hardness test the highest value is found in the variation of aluminum silicon (Al-Si) mesh 100 with a hardness value of 88.67 HD. The results of friction testing on all conditions of the lowest wear values are in the variation of aluminum silicon (Al-Si) mesh 100 which is dry testing 11.687 mm3 / hour, water 11.006 mm3 / hour, oil 14.524 mm3 / hour, and the results of the highest friction coefficient the namely in the mesh 100 which is dry testing 0.7239, water 0.7228, and oil 0.6589.
