Stress–Strain Properties of a Microwave-Irradiated Polymer Composite Based on Rubber PDI-3A
摘要
Abstract
The stress–strain diagram of a polymer composite material based on rubber PDI-3A filled with thermally expanded graphite or potassium chloride has been studied before and after microwave treatment for 300, 600, 900, and 1200 s. It has been found that the ultimate tensile strength and strain increase twofold after a 300-s microwave treatment and testing at 223 K. A significant decrease in the stress–strain properties of the synthesized composites with an increase in the test temperature or microwave treatment time is observed.
