Material optimization of carbon/epoxy composite rotor for spacecraft energy storage


Varatharajoo, Renuganth and Salit, Mohd Sapuan and Goh, Kian Hong (2010) Material optimization of carbon/epoxy composite rotor for spacecraft energy storage. International Journal of Multiphysics, 4 (2). pp. 95-101. ISSN 1750-9548


An investigation to optimize the carbon/epoxy composite rotor is performed for the spacecraft energy storage application. A high speed multi-layer rotor design is proposed and different composite materials are tested to achieve the most suitable recipe. First, the analytical rotor evaluation is performed to establish a reliable numerical rotor model. Then, finite element analysis (FEA) is employed in order to optimise the multi-layer composite rotor design. Subsequently, the modal analysis is carried out to determine the rotor natural frequencies and mode shapes for a safe operational regime below 50, 000 rpm.
