Abstract
The purpose of the study is to determine the best composition variation of the fifth variation of the composition of the composite material against the wear test, hardness test, tensile test comparing values with the safety standards of the brake lining composite SAEJ 661. Making the specimens was performed by mixing the ingredients with a mixer for 15 minutes and then do the process of compaction, with a load of 4 tons and detained achieve holding time is desired, then dies (mould) are placed in the oven and do the sintering process at a temperature of 150<sup>0</sup> C for 180 minutes and specimens removed from the mould, the process of finishing and testing. These test results show that the composition of the material that is on variation V best price obtained 96.575 HBN hardness, wear rates of 1,29x10<sup>-6</sup> gr / (mm<sup>2</sup>.detik), and a tensile strength of 0.842 MPa, but the brake friction material not meet safety standards SAEJ brake 661.
