The pursuit of carbon fiber reinforced plastic (CFRP) composite aircraft wings with high-aspect-ratio planforms has garnered significant interest in recent research endeavors. In this study, we present a comprehensive multidisciplinary design framework that integrates a two-way coupled aerodynamic-structural simulation, multiscale CFRP composites modeling, structural sizing techniques, and a NSGA-II multi-objective genetic optimization algorithm. This innovative approach enables the design of CFRP composite aircraft wings with diverse planforms and airfoil shapes. The proposed multi-objective design framework incorporates the aerodynamic drag coefficient and wing structural weight as objective functions, with wing planform parameters and airfoil shapes serving as design variables. Furthermore, the study explores the impact of various fiber types and resin types, including both thermoset and thermoplastic resins, on the aircraft wing design. Through rigorous analysis, we aim to investigate the effects of next-generation fibers and resins on CFRP composite aircraft wings featuring different shapes. The study provides a significant step forward in optimizing CFRP composite aircraft wings, offering an understanding of the intricate relationship between material selection and aerodynamic performance.
