Abstract

The train is currently trusted by the people of Indonesia as a cheap and safe means of transportation. One from that must be met by a train is a reliable braking system. Generally the train brake block material is used gray cast iron brake block. One of materials based composite as a substitute for train brake block are the Al-SiC (Aluminium Silica Carbida). The Al-SiC composite material has hard and soft properties. Aluminium (Al) as a matrix and SiC as reinforcement. Metal material composite used for the reseach is Al-SiC composite with composition of SiC 15%, 10%, and 15% made through a process of stir casting. The specimens were tested tensile strength and impact tests. The test of results : tensile test for cast iron = 188.56 MPa; aluminium = 131.97 MPa; Al-SiC 5% = 127.17 MPa, 10% = 136.41 MPa dan 15% = 107.26 MPa. The result of the energy absorbed of impact test are cast iron = 2.17 Joule; aluminium = 8.67 Joule; Al-SiC 5% = 4.00 Joule, 10% = 4.67 Joule and 15% = 2.83 Joule. From the result of test, so replacement of cast iron brake material block is composite brake material block with a composition 10% of AL-SiC. Key words : gray cast iron, aluminium-silicon carbide, tensile strenght test and impact test.
