Abstract

The present study is devoted to tensile modulus of recycle PET/clay nanocomposites based on the various conventional models. Some models such as Paul and Takayanagi provide good results, when compared with the experimental data. Hirsch model predicts more accurate data by the x value of 0.1 revealing that the tensile modulus of current nanocomposites conforms to the inverse rule of mixture model. The comparison between experimental and theoretical results of Guth models confirm the necessity for taking account of stiffening factors such as aspect ratio of silicate layers. The theoretical data present a good agreement with experimental data considering the aspect ratio of 8 for silicate layers. In addition, the orientation and 3D random dispersion of the nanoclay platelets should be assumed according to Halpin–Tsai model. Further, some simplifications and modifications are carried out on the several models to enhance their predictability. The modified models are too simple, because they only require to Young’s modulus and volume fraction of components for prediction.

再生PET/粘土纳米复合材料的拉伸模量建模

摘要

本研究致力于基于各种传统模型的回收 PET/粘土纳米复合材料的拉伸模量。与实验数据相比,Paul 和 Takayanagi 等一些模型提供了良好的结果。Hirsch 模型通过x预测更准确的数据0.1 的值表明当前纳米复合材料的拉伸模量符合混合物模型的逆规则。Guth 模型的实验和理论结果之间的比较证实了考虑硬化因素(例如硅酸盐层的纵横比)的必要性。考虑到硅酸盐层的纵横比为 8,理论数据与实验数据非常吻合。此外,纳米粘土片晶的取向和 3D 随机分散应根据 Halpin-Tsai 模型进行假设。此外,对几个模型进行了一些简化和修改,以增强其可预测性。修改后的模型过于简单,因为它们只需要杨氏模量和组件的体积分数进行预测。
