本文的主要目的是研究,在实验的帮助下,在聚碳酸酯薄膜的机械性能的诱导各向异性。已知聚合物材料中的分子取向通过冷成型发生。在这项研究中,冷成形是在室温下进行的拉伸试验机。聚碳酸酯薄膜在两个阶段进行检查。在第一阶段,加载试样,同时改变预应变,在第二阶段,加载试样,同时改变材料方向。主要的研究结果是,预应变几乎没有影响的各向异性和材料的方向施加重大影响。此外,本文总结了各向异性特征数据,最大应力,弹性模量和破坏应变的比较。
The prime aim of this paper is to investigate, with the help of experiments, the induced anisotropy of mechanical properties in polycarbonate films. It is known that a molecular orientation in polymer materials occurs through cold‐forming. In this study, cold forming is performed at room temperature on a tensile testing machine. The polycarbonate films are examined in two phases. In the first phase, the specimen is loaded, while the prestrain is varied, and in the second, it is loaded, while the material direction is varied. The main findings are that the prestrain has virtually no influence on the anisotropy and that the material direction does exert a major influence. Furthermore, this paper summarizes comparisons of anisotropic characteristic data, maximum stresses, elasticity moduli and failure strain.
