Abstract

In this research, the researcher want to understand and make sample of motorcycle brake lining by using environmentally friendly composite material with some variation of material composition to know the level of hardness, wear and coefficient of friction of the brake pad. The material used in this research is fiberglass, copper powder variation of mesh 50, 60, 70 and 100, bamboo skin carbon, calcium carbonate, barium sulfate and polyester resin with catalyst as binder / matrix. Then tested friction with 15 kg load for 3 hours with dry test, water spraying and oil spraying with standard testing of SNI 09-2663-1992 then calculated the wear and coefficient of friction, and tested the hardness by using Durometer tool with ASTM standard D2240. From the result of the average wear and tear on testing the effect of dry, water and oil that brake copper mesh 100 is lower than with other variation brake lining that is equal to 49,7576 mm3 / hour, 60,1238 mm3 / hour and 60,0783 mm3 / h on friction test for 3 hours. The coefficient of friction on the test of the influence of dry brake lining bridge variation of copper mesh 100 highest, on the friction test for 3 hours that is equal to 0.8857, on the friction test of brake fluid water variation of copper mesh 60 has the highest coefficient of friction of 0.8297, brake fluid brake fluid variation variation mesh 70 has the highest friction coefficient of 0.8663. The hardness of brake liner bracelet variation of copper mesh 100 is better than the other brake lining of 87,83 ShoreD, in micro photo testing after brake fluid brake variation variation of copper mesh 70 having adhesive bonding failure while brake lining of copper mesh variation of 100, 60, 50 experienced cohesive bonding failure. Keywords: copper powder, polyester, friction test, hardness, micro photo
