摘　　要：建立了三维机织物单元体的结构模型。织物的结构模型是通过对织物断面的观察及一些基本假设而建立的。在此基础上计算了三维机织物单元体中的纱线长度、接结纱、经纱取向角及纤维体积分数,并将纤维体积分数的理论计算值与测试结果进行了比较,两者吻合较好,这表明本研究建立的三维机织物结构模型是正确的。The unit cell model of 3D woven structure is established in this paper. By means of observing the section of 3D woven and some assumption ,the unit cell model of 3D woven structure is established in this study. On the basis of the model mentioned above, the length of constituent yarns inside the cell and the orientation angle of binders and warps as well as the fiber volume fraction are calculated. The calculated fiber volume fraction is compared with test results from selected samples of 3D woven composites. A good agreement is demonstrated between the theoretic predictions and the experiment results, this indicates that the unit cell model of 3D woven structure established above is right.
