Comparative Structural Characterization of Fiber Reinforced Composite Rotating Disc: A Validated Investigation

The objective is to determine the mechanical behavior of fiber-reinforced composite of a rotating disc by using experimental and Finite Element Analysis (FEA) studies. Firstly, the FEA analysis have been conducted for two different families under the loading conditions of 600 RPM as rotational velocity with external frictional force as 10 N. In which, the seven different composite specimens such as Epoxy-Carbon-UD-Prepreg-SiC, Epoxy-Carbon-UD-Wet-SiC, Epoxy-Carbon-Woven-Prepreg-SiC, Epoxy-Carbon-Woven-Wet-SiC, Epoxy E-Glass-UD-SiC, Epoxy-E-Glass-Wet-SiC and Epoxy-S-Glass-UD-SiC are undergoing for structural characterization analysis with help of FEA tool. Apart from these materials, the four base materials were also analyzed through FEA for comparison under the same loading conditions. Secondly, the experimental study was conducted to investigate the applicability of the FRP solid disc brake rotor with Silicon Carbide (SiC), in this regard the ASTM standard specimens based pin on disc apparatus for Carbon Woven based Ceramic-composite was prepared. The validation is also executed in between displacements of these two approaches. Finally, this work confirmed that the carbon fiber ceramic matrix composite materials are the good materials to resist rotodynamic loads therefore the work also strongly recommended that CCMC to be implemented in the fabrication of rotating components like aircraft and automotive disc brakes.
