The Influence of Modified Additives on Dynamic Properties of Polymeric Materials Based on Ethylene-Vinyl Acetate

Abstract

The article deals with the problem of creating vibration damping polymeric materials with high damping properties in a wide temperature range. The purpose of the article is to study physical-mechanical properties of composites based on ethylene-vinyl acetate by adding various modifiers in the form of resins. The main method to investigate this problem is the method of dynamic mechanical analysis, which makes possible to obtain viscoelastic properties of polymeric materials under the influence of an oscillating load at various temperatures and oscillation frequencies. Due to the established experimental dependencies, the authors have determined the type of resin, which improves the damping properties and increases the stiffness of the composites based on ethylene-vinyl acetate. Moreover, the authors have defined the limit of working capacity of composites with resins at negative temperatures.
