Abstract

This work is aimed at studying the stiffness evolution of clustered composites and nanocomposites by FEM analysis. In fully dispersed composites and nanocomposites, proper modeling requires accounting for nanoparticle aspect ratio, volume fraction, and angle of orientation. In addition to these, the FEM model proposed in this work accounts for number of nanoparticles and volume fraction of nanoparticles in the cluster. The proposed approach allowed to calculate the longitudinal modulus and the other elastic constants of clustered composites, showing significant differences with the modulus of fully disperse composites.

簇状复合材料和纳米复合材料刚度演变的有限元分析

摘要

这项工作旨在通过有限元分析研究簇状复合材料和纳米复合材料的刚度演变。在完全分散的复合材料和纳米复合材料中，适当的建模需要考虑纳米颗粒的纵横比、体积分数和取向角。除此之外，本工作中提出的 FEM 模型还考虑了簇中纳米粒子的数量和纳米粒子的体积分数。所提出的方法可以计算成簇复合材料的纵向模量和其他弹性常数，与完全分散的复合材料的模量有显着差异。
