Formation and Failure of Elastomer Networks via Thermal, Mechanical and Surface Characterization

Abstract

This work focussed upon development of ESCA, SEM/EDAX, TGA, DSC and TMA methodologies for synthetic elastomer compounds typically used in tank track pad service by the U. S. Army. The initial goal was to develop a molecular model of the failure mechanisms that lead to costly pad replacement. Exploratory measurements were conducted on fully compounded, uncured rubber, and pre- and post-service track pads. Studied also were laboratory-prepared samples involving variable matrix (SBR, EPDM and 50/50 SBR/BR) as well as zinc oxide particle shape and size. An initial data base has been accumulated with surface and thermo-mechanical analysis that could provide useful structure-property information for further research and development of engineering elastomers.
