Hybrid composites have two or more reinforcement ratios, and they are among the preferred materials in many engineering applications due to their unique properties, such as lightness, low cost, easy applicability, and high strength. This study investigated the effect of sintering aluminum matrix graphene (0.1% and 0.5%) and SiC (10% and 20%) reinforced hybrid composite with an ultra-high frequency induction heating system on mechanical and physical properties. Powder mixtures were prepared using a three-dimensional mixing system were prepared according to the experimental design created by the Taguchi method at three different temperatures (580, 600, and 620 ℃), three different pressures (80, 90, and 100 bar), and three different sintering times (5, 7 and 10 min). It was produced, and its hardness, density, and microstructure were examined. ANOVA analysis was performed on the results obtained and a mathematical model was created. As a result of the experiments, the highest hardness value of the 0.1% graphene and 10% SiC reinforced hybrid composite was 90.4 HB at 100 bar pressure, 10 min sintering time and 580 ℃ sintering temperature, and the highest hardness value of the 0.5% graphene and 20% SiC reinforced composite was 100 bar. The pressure was obtained as 103.5 HB at 5 min sintering time and 600 ℃ sintering temperature.
