Application of dynamic mechanical analysis and linear dilatometry in the study of the mechanisms of climatic aging of transparent thermoplastics in natural conditions

Abstract

The volume, assortment and application areas of transparent thermoplastics, including as construction materials in modern hightech products and devices, are expanding every year. At the same time, parts of products made from these materials are one of the most sensitive elements of the product exposed to the environment. Assessment of material performance under the influence of environmental factors is carried out by conducting tests in full-scale and laboratory conditions. The use of physical research methods makes it possible to understand the mechanism and kinetics of the aging processes of thermoplastic materials and to increase the reliability of predicting performance under natural conditions. In addition, the use of the proposed research methods makes it possible to more reliably evaluate and, if necessary, correct the methods of accelerated climatic tests when comparing the aging mechanisms in natural and artificial conditions.
