Abstrakt
The composite reinforcements preforming including complex deformability behaviours. Numerical
simulation analysis can effectively predict these behaviours and improve the preforming quality. Based
on the related theory of continuum mechanics, this paper proposes a hyperelastic constitutive model to
describe the nonlinear anisotropic mechanical behaviour of braided fabrics due to large deformation
during the forming process. The tensile strain energy generated by the warp and weft stretching and the
shear strain energy caused by the angle change between the warp and weft is considered in this model.
The parameters of the hyperelastic constitutive law are identified by the bias-extension test. And it’s
also used to simulate the forming process of the braided fabrics.
