Application of Taguchi Method for Optimizing the Parameters of Thermal Properties of Al/SiC-Gr Hybrid Composites

Using the Taguchi method, this study presents a systematic optimization approach for thermal properties of Al/SiC-Gr composites which were synthesized by using metallurgy technique. The thermal conductivity, diffusivity and specific heat capacity measurements were performed on a thermal physical testing instrument using a laser flash method. The controllable factors such as wt. % of SiC, wt.% of Gr and heat treatment duration have been optimized. The percentage contribution of each controllable factor was also determined. The heat treatment is the most influential factor and its value of percentage contribution is up to 99.57%, 99.46% and 97.74% for thermal conductivity, thermal diffusivity and specific heat respectively.
