有机玻琍作为结构实验模型的材料目前国内己得到相当多的应用。有鉴于该类材料的种种特性,为了保证得到可信的实验结果和探求提高实验精度的方法,对有机玻琍的机械性能加以特别的研究是十分必要的。本文仅就机翼结构模型静力强度实验中遇到的某些问题进行了初步研究。文中提供了一种国产有机玻琍材料的弹性模数。泊松比等性能资料,介绍了一些简便而有一定精度的性能测试方法,也初步探讨了周围空气的温度、湿度对有机玻琍弹性模数的影响规律,还验证了该类材料静力实验中的一个可贵性质——时效变形中的“正比例”规律。由此得出结论,在应力较小的情况下。可以足够精确地把这类有机玻琍当作完全弹性材料一样使用。
As an experimental model of the structure of organic glass material currently has a considerable number of applications. In view of the characteristics of these materials, in order to ensure credible experimental results and to explore ways to improve the accuracy of experiments, the mechanical properties of organic glass to be a special study is necessary. In this paper, only some problems encountered in the experiment of static strength of the wing structure model are studied. The article provides a domestic elastic modulus of organic glass material. Poisson’s ratio and other performance data, introduced some simple and have a certain degree of accuracy of the performance test method, but also a preliminary discussion of the ambient air temperature and humidity on the impact modulus of elastic modulus, also verified the static test of such materials A Valuable Character in “A Normal Proportional” Law of Aging. This concludes that under less stressful conditions. This type of organic glass can be used with sufficient precision as a fully elastic material.
