A model for the elastic coefficients of fiber-reinforced materials is applied toward the analysis of the tensile and shear moduli of nanocomposites reinforced by rod-like cellulose nanoparticles. Our formalism integrates results from percolation theory with micromechanical and effective medium approaches. Polydispersity in the fiber length distribution and anisotropies in the stiffness coefficients of cellulose nanoparticles are taken into account explicitly. Results from calculations employing our model display reasonable agreement with experimental measurements of the moduli as functions of the filler volume fraction for several cellulose nanoparticle-reinforced thermoplastic-based composites.
一种纤维增强材料弹性系数模型被应用于分析由棒状纤维素纳米颗粒增强的纳米复合材料的拉伸和剪切模量。我们的形式主义将渗流理论的结果与细观力学和有效介质方法相结合。纤维长度分布的多分散性和纤维素纳米颗粒弹性系数的各向异性被明确考虑在内。我们的模型计算结果与几种纤维素纳米颗粒增强热塑性基复合材料的模量作为填充剂体积分数的函数的实验测量结果具有较好的一致性。
