| The superior properties of composite materials compared to traditional materials led to significant attention in the development of disk brake manufacturing. In many industrial and automotive applications where performance and durability are dominant, disk brakes are critical components. The reinforcement of a lightweight metal matrix, such as aluminium, with a hybrid of 15% and 20% silicon carbide (SiC) and 10%, 15%, or 20% Zinc oxide (ZnO) may enable the hybrid composite to meet specific performance standards and improve the brake's efficiency and lifetime. Wear test and hardness were performed according to ASTM standards on hybrid composite samples. Minitab 19 - Design of Experiments (DOE) approach was utilised to analyse the experimental results of the effect of time on the specific wear rate under different loads. Minitab 19 software was used for time-series trend analysis to visualise these effects. The residuals-versus-fitted-values plot was used to assess the regression model and validate its assumptions. The fitted values represent the predicted specific wear rate over time, while the residuals are the differences between the observed and predicted specific wear rates. Additionally, a residuals-versus-observation-order plot was used to illustrate the correlation of these differences over time. According to the time trend analysis of the specific wear rate, the highest wear resistance was of sample A5. Hardness was maximum at the A2 and A5 samples. The optimal composite material identified from these tests was then used as input for the ANSYS 2022-R1 workbench. A static structural analysis was performed to evaluate stress, strain, and elastic energy. Furthermore, a thermal analysis was conducted to assess temperature distribution, total heat generation, and heat flux within the material. | ||
