Abstract
This thesis presents a comprehensive study on a hybrid CubeSat structure that incorporates additive manufacturing techniques for its main framework and utilizes Aluminum 6061 for the rails through traditional manufacturing methods. This innovative approach exceeds the minimum acceptable resonance frequency thresholds for satellite missions while achieving a mass reduction of 50% compared to traditional microsatellite structures of similar size. The investigation reveals a robust structure, as demonstrated by the derived safety factor from semi-static simulations. Further analysis of stress and displacement under random vibration loads indicates that the structural integrity remains uncompromised. The primary structural components made from Polyether Ether Ketone (PEEK) material, weighing 109 grams, and highlight the effectiveness of high-performance thermoplastics in maintaining rigidity and reducing overall mass.
