PENGARUH SINTERING 700°C, DENGAN TEKANAN TETAP 117 MPa TERHADAP KARAKTERISTIK GREEN BODY BRAKE LINING CESSNA 208B

Airplanes are a means of air transportation that is fast, precise, guarantees safety and saves time. Cessna aircraft are one of the aircraft in demand by passengers in remote areas in Indonesia. This aircraft has a braking system with one of its components being the brake lining. Brake lining is one of the most important components in the brake system that functions to stop the aircraft. In this study, a prototype brake lining was made from Metal Matrix Composite (MMC). MMC made this brake lining prototype through a powder metallurgy process with the initial process of the powder being weighed, mixed, compacted, and heated with argon sintering at a temperature of 700oC called the green body. The purpose of this study was to determine the characteristics of the green body brake lining with a pressure of 117 MPa and a sintering temperature of 700oC. The results of this study are the hardness value of the green body 41.26 HRB is a Cu alloy with soft material properties and will increase in hardness if with heat treatment such as quenching, tempering, or annealing. The results of the wear test of 0.000550 mm³/kgm are in the category of materials that have good wear resistance. The effect of the sintering process on the characteristics of MMC materials is to increase tensile strength, hardness, and toughness. MMC by improving the microstructure, can increase density, and reduce porosity in MMC.
