Physical Parameters of Polymer Composite Materials Created on the Basis of Low and High Molecular Weight Rubbers
Abstract
The objective of this work is the further development theoretical foundations of structural and mechanical behavior of the filled three-dimensionally cross-linked elastomers. The use of mathematical modeling it was possible to create three-dimensionally cross-linked, filled with dispersed particles, frost-resistant elastomers based on low and high molecular weight rubbers at the minimal cost. Theoretical and experimental data are compared and their good convergence is shown. A comparison of the physical parameters of the composites showed that the deformation characteristics of the composite based on high molecular rubbers are many times higher than composites based on low molecular weight rubbers, and also their glass transition temperatures differ sharply. The created composites are recommended as a structural material in relation to the engineering problem of creating wear-resistant parts and components of automobile and aviation vehicles operating in a wide temperature range, including in the Far North and the Arctic
