Abstract: The composite joints are increasingly used in foreign civil large-scale aircraft due to their light weight, high strength and designable structure. This work focused on the mechanical behaviour of a newly designed composite wound joints under tension and compression using finite element modelling method. Three typical structures, i.e., basic configuration, shuttle configuration, cone configuration, were compared to get the influence of different configurations on the mechanical behaviour of composite joints. Results show that all three structures have satisfying strength. The slope angles of shuttle and cone configurations were furtherly studied to increase the application of composite wound joints.
