Abstract: A design method combining multi-scale modeling and genetic algorithm is proposed for the collaborative optimization of stiffness and damping performance of embedded co-cured stitched damping structure composites. Firstly, the theoretical model of in-plane equivalent elastic parameters of the composites is established, and its accuracy is verified by combining experiments and finite element simulations, and the influence law of the change of the stitched structure on the stiffness and damping performance of the composites is revealed, and then the optimal design of the stitched wire diameter and the stitching spacing is carried out by the genetic algorithm. The results show that under certain conditions, the loss factor of the material is improved by 8.8 times relative to the unstitched damping structure while the stiffness is reduced by only 9.2% when the percentage of stitch area is 2.06%. This study will provides a new scheme for the design of high stiffness and large damping composites in aerospace, automotive and other fields.
