| Abstract: | In the article,focusing on the prediction method of the three-dimensional four braided composite effective modulus,firstly the three-dimensional four braided composite single cell is divided into some rectangular body unit,then using the material parameter in the Gauss integral point to calculat the stifines matrix of the unit,finally,the whole cell stiffness matrix is formed by the element stiffness matrix,and then the effective modulus of the 3D four braided composite could be predicted. |

| Keywords: | the three-dimensional braided composite materials single cell effective elastic modulus |
