Abstract

In this paper, experimental data on studying the effect of thermal stresses on the “crazing resistance” of the imported Makrolon polycarbonate and domestic VTP-8/PK-EA-7.0 polycarbonate in comparison with serially applied organic polymethylmethacrylate glasses, such as SO-120 nonoriented glass and AO-120, were presented. The studies were performed by the method of studying the resistance of organic glasses to thermal shocks developed at the National Research Center “Kurchatov Institute” and National Research Unitary Institute “All-Russian Institute of Aviation Materials” by creating thermal stresses on the surface of a material in the course of experiment under thermal shocks with the use of a metallic indenter. The experimental data on the initial temperature of the formation of residual stresses in polycarbonate and the relaxation of stresses in polycarbonate after thermal shocks were measured.

热应力对光学透明聚碳酸酯“抗龟裂性”的影响

摘要

本文通过实验数据研究热应力对进口模克隆聚碳酸酯和国产VTP-8/PK-EA-7.0聚碳酸酯“抗龟裂性”的影响，并与系列应用的有机聚甲基丙烯酸甲酯玻璃（如SO-120）进行比较。提出了无取向玻璃和 AO-120。这些研究是通过国家研究中心“库尔恰托夫研究所”和国家研究单一研究所“全俄罗斯航空材料研究所”开发的通过在有机玻璃表面产生热应力来研究有机玻璃的耐热冲击性的方法进行的。使用金属压头在热冲击下进行实验的材料。
