【 摘 要 】

The material of composite hybrid Al / (SiCw + Al2O3) is a mixture of fine aluminium powder as a matrix while Silicon Carbide whiskers (SiCw) and Alumina (Al2O3) as reinforcement. Powder metallurgy method is used to manufacture composites according to the form of test specimens. Testing without treatment and after sintering treatment with temperature parameters and sintering time of 500 and 600°C at holding time 6 hours. This research was conducted to know the properties of thermal conductivity, hardness, density and SEM analysis after sintering process. The results show that the sintering process that has been carried out can provide a percentage increase and affect the composite properties. Improved thermal, hardness and density occurs due to stronger or denser interface bonds between the matrix and reinforcement influenced by increasing sintering temperatures, so sintering processes can affect composites on physical and mechanical properties.
