Technique to Estimate the Properties of Epoxy Composite Materials Used in a Humid Environment
Abstract
The results of experimental studies of epoxy polymer before and after exposure in the climate chamber at high humidity are presented. The mean values of tensile and shear strength as well as the values of standard deviation and coefficient of variation have been determined. It has been found that the injection of dispersed fillers that consist of a mixture of aluminum powder and carbon-containing powder into the epoxy polymer composition makes it possible to reduce the coefficient of variation by 40%. The long-term exposure of epoxy polymer samples in a humid environment led to a slight decrease in the mechanical properties (6%) as well as to a significant increase in the standard deviation (by more than 65%) and the variation coefficient (by 77%).
期刊介绍：
Steel in Translation is a journal that represents a selection of translated articles from two Russian metallurgical journals: Stal’ and Izvestiya Vysshikh Uchebnykh Zavedenii. Chernaya Metallurgiya . Steel in Translation covers new developments in blast furnaces, steelmaking, rolled products, tubes, and metal manufacturing as well as unconventional methods of metallurgy and conservation of resources. Papers in materials science and relevant commercial applications make up a considerable portion of the journal’s contents. There is an emphasis on metal quality and cost effectiveness of metal production and treatment.
