Notes:
As for 2.5-D layer-to-layer angle interlock braided composites, the cross section of thewarp tow was represented in double-convex lens form, and the center line of the warp tow wasalong the sinusoid. The arranging characteristic of weft tow fibers along the cross section outline ofthe longitude fibers was studied in detail. A novel finite element model for 2.5-D braidedcomposites was established to predict elastic modulus. The finite element software ANSYS wasadopted to study the mechanical properties of the model and presented its stress nephogram, and theinfluence of the braided structure parameters on the elastic modulus of this material was analyzed indetail. To validate this model, qualified experimental samples were made by VARTM technique,and then tensile tests were performed to determine the mechanical properties. The results show thatthe conclusions of finite element method (FEM) fit well with the experimental values, and thismodel can be used to predict effectively the macro modulus of 2.5-D braided composites
