Increasing the Reliability of Predicting the Properties of Polymer Composites in Hygrothermal Aging

摘要

Two main requirements are imposed on polymer composites produced for manufacturing structural elements for mechanical engineering. First, these composites must have good mechanical characteristics, and second, the reached values of strength, moduli of elasticity, and other characteristics must not become noticeably worse after long functioning of the material in a construction [ 1 ]. In operation of machinery, polymer composites must be resistant to the action of moisture, heat, atmospheric oxygen, mechanical loads, and other factors, which is checked by long and costly tests [2-5].
