Abstract This paper proposes a micromechanical approach aimed at identifying the response of unidirectional fuzzy fiber composites undergoing inelastic fields. Fuzzy fibers are reinforcement fibers coated with radially aligned straight or wavy carbon nanotubes grown through chemical deposition process (PVD or CVD). Due to this nature, the composite with fuzzy fibers is described by three scales: i) the microscale consisting of carbon nanotubes and their surrounding matrix, ii) the mesoscale containing the fiber, the nanocomposite and the matrix, and iii) the macroscale related to the overall fuzzy fiber composite. The developed framework considers for the mesoscopic scale an analytical formulation, based on the composite cylinders assemblage (CCA) method, combining the principles of the Transformation Field Analysis (TFA) technique. A numerical example that includes comparisons with full field homogenization strategies confirms the accuracy of the framework to predict the overall response, as well as the average local fields of the constituents.

具有直线或波浪形碳纳米管的模糊纤维复合材料非弹性机制的多尺度建模

摘要 本文提出了一种微机械方法，旨在识别单向模糊纤维复合材料在非弹性场中的响应。模糊纤维是涂有通过化学沉积工艺（PVD 或 CVD）生长的径向排列的直线或波浪状碳纳米管的增强纤维。由于这种性质，具有模糊纤维的复合材料由三个尺度描述：i) 由碳纳米管及其周围基质组成的微观尺度，ii) 包含纤维、纳米复合材料和基质的中尺度，以及 iii) 宏观尺度整体模糊纤维复合材料。开发的框架考虑了细观尺度的分析公式，基于复合圆柱组合 (CCA) 方法，结合转换场分析 (TFA) 技术的原理。
