Abstract A representative volume element (RVE) and shear specimen model of satin weave composite fastener is established and numerical model of prediction on effective elastic module is presented based on periodic boundary conditions. Cross-scale numerical simulation of shear failure in different load angle is implemented. The uniaxial shear tests of satin weave composite fastener are performed. The shear strength obtained from finite element method (FEM) is in good agreement with the experimental results, which demonstrated the feasibility of the FEM model. The influence of different load angle in shear failure mode and strength is discussed, which indicates the shear strength decreases as the load angle growth due to different failure mode.

Key words： braided composite fastener shear strength periodic boundary conditions FEM
