摘要
提出纱态概念 ,解决了任意结构三维机织预制件的结构表征问题 ,提出了交叉等效曲面板模型 ,借助三次多项式插值原理 ,建立了反映三维机织复合材料本构关系的计算机模拟模型 ,并以试验进行了验证。
This paper presents the concept of yarn state, solving the descriptive problem of preform structure of any 3 D woven composite. A cross equivalent curve board model is expounded, and with the help of cubic polynomial interpolation theory, the computer simulation model is developed which reflects the constitutive relation of 3 D woven composite. In addition, contrast tests are conducted to verify the model.
