| Abstract: | The classical theory of laminated plates and the first-order shear deformation theory based on the Mindlin hypothesis are used to analyze the stiffness of hollow-box-section beam with 2-step three-dimensional braided composite.The formulas for calculating the coefficients of the tensile stiffness,flexural stiffness,torsional stiffness and shear stiffness as well as various coupling stiffness are derived.All these coefficients are functions of variables such as the fiber and matrix types,yarn orientation,total contents of fiber volume,and the geometric size of the hollow-box-section beam. |
