Research Progress on Micromechanical Model of 3D Stitched Composites

Due to the complex micromechanical structure,mechanical performance of 3D stitched composites has a essential difference from that of laminates.To predict mechanical performance of the 3D stitched composites,many researchers simulate the true inner structure by establishing theoretical analysis model.This paper summarized some main analysis model and indicated the model's merits and demerits,which can instruct mechanical workers to choose numerical model reasonably and predicted the mechanical performance accurately.
