Recently, it is urgent to reduce the energy consumption rate from environmental problems such as global warming and the exhaustion of fossil fuels. However, it is difficult to reduce the weight and to improve the efficiency of cooling by using existing materials. In recent years, carbon fiber (CF) having high thermal conductivity, electro conductivity, and strength properties are used as reinforcing material in composite material. The Aluminum (Al) based composite material containing CF has higher thermal conductivity than pure Al. In addition, the extrusion method is a relatively inexpensive manufacturing method, and it has been found that it has high hardness and high filling rate. However, measurement of mechanical properties of the composite material comes short. In this study, the thermal conductivity and Vickers hardness of the composite material prepared using extrusion method are evaluated. According to these results, as the content of carbon fiber was increased, the filling rate decreased, but the thermal conductivity and Vickers hardness tended to increase.
