Exploration of the effect of complex plasticization on the rheo-logical parameters of polymer composites

Abstract

The paper explores the rheological characteristics of unfilled and filled epoxy resins ED-16. Existing plasticizers and modifiers of epoxy resins are considered. The existing mechanisms of plasticization are described. A new method of complex plasticization of high-viscosity epoxy resins with complex petroleum products is proposed. A mathematical method for modeling the processes of structure formation is proposed and a description of the processes of structure formation in composite materials as a result of complex plasticization is given. The conditions for the flow of rheological processes are considered. Mathematical models of structure formation in composite materials as a result of complex plasticization have been built. As a result of studying and modeling the rheological properties of filled and unfilled epoxy resin ED-16, theoretical aspects of plasticization of epoxy systems have been developed and a method for complex plasticization of high-viscosity ED-16 resin with a mixture of mineral and vegetable oils has been proposed, which makes it possible to obtain epoxy composites with excellent rheological characteristics. The effect of the filler on the strength and rheological properties of high-density composites filled with optical glasses has been substantiated. Mathematical models and methods for modeling the plastic-viscous properties of filled epoxy composites have been developed and substantiated, depending on the formulation and technological parameters of the compositions. The prospects for the application of the developed technologies for the structural-parametric synthesis of composite materials with given parameters of structure and properties are shown.
