Abstract

A lemniscates micro model is established according to the fabric of the three-dimensional and four-step braided composite. On the base of this model, the distribution of thermal stress and strain of the three-dimensional and four-step composite during the preparation process is analyzed by using FEM software. The effective elastic modulus and the effective thermal expansion coefficient of the three-dimensional and four-step composite at room temperature are simulated and compared with their analytic solution. These results provide an accurate simulation method and give reference to design, process and use this kind of composite.
