Abstract. The train is one of the biggest favorite transportation in Indonesia. One of the most important components of a train is the braking system. Brakes have several functions such as reducing speed and stopping trains. One of the most frequently replaced components is the brake block. Since 2016, train brake blocks in Indonesia have started to change from metal brakes to composite brakes, but unfortunately Indonesia must import from abroad. Geopolymers with carbon fiber can be an alternative material to replace conventional brake blocks, because geopolymer composites have more advantages than conventional brake blocks such as cheaper, light in weight, and high temperature resistant. There was 3 methods experiment from geopolimer specimen that is friction test, flextural test, and SEM test. The test result show that composite who contain Fly Ash 50%, Kaolin 40%, of Silica Fume 10%, CaO 12 grams, Carbon Fiber and sulfur has higher value of friction coeficien when we add sulfur 10% than specimen without sulfur and has a lower value of friction coeficien when we add carbon fiber 10% than specimen without carbon fiber, for flexural test it can reach a strength of about 86 MPa with Flexural Modulus around 20 GPa . Microstrucutre from SEM test show that geopolymer without fiber varbon have crack who make a low flexural strength. And geopolymer with carbon fiver have not any crack and make a strength more higher.
