摘要
用Abaqus建立纳米碳管增强复合材料的平面应变模型,分析了材料的宏观力学特性,研究了在不同碳管添加量、碳管分散性、碳管分布角度以及不同基体情况下,材料力学特性的变化规律,评价了碳管增强效果的影响因素及影响程度。将此方法得到的材料力学性能数据与细观力学模型的理论预测和实验结果进行了比较,验证了该方法的可靠性。
In this paper, the plane strain models of carbon nanotube （CNT） reinforced nanocomposites are established by ABAQUS software to investigate the overall macroscopic mechanical properties of nanocomposites. The influences of CNTs with different volume fractions, and different dispersion states different alignments and different matrices on mechanical properties are studied. The reinforcectors of CNTs and their effects are evaluated. Finally, the results provided by the present numerical model are verified with those obtained from a micro-mechanics based theoretical model and experiments. This work provides a powerful and simple method to evaluate the mechanical properties of new types of nanocomposites.
