title = "Material modeling of 2×2 braided composites using a beam approach",
abstract = "Braiding is an automated preforming process for liquid molded composite materials. As braided composites offer a big variation in the textile yarn architecture, a material modeling approach has to predict the influence of yarn architecture on material stiffness and strength. The approach presented in this paper uses a finite element unit cell model to calculate the homogenized macroscopic material properties of a 2×2 biaxially braided carbon/epoxy composite. To reduce the effort for mesh generation, beam elements represent the longitudinal properties of the yarns and continuum elements represent transversal properties of yarns and matrix pockets. The predicted elastic properties show good correlation with micromechanical results. Further studies about the influence of out-of-plane boundary conditions and coupling of beam and continuum elements are outlined.",
