Experimental Research of Thermal-Oxidative Aging on the Mechanics of Aero-NBR

CODEN: JTEVAB

Abstract

In order to analyze the rules of thermal-oxidative aging on the mechanics of Aero-NBR, a hot air accelerated aging test platform is designed and used to research the influence of thermal-oxidative aging on Aero-NBR’s mechanical property. The experimental results show that the tensile strength of Aero-NBR increases with increasing aging time under a certain temperature, and the elongation at failure first increases and then decreases; under the effect of pressure load, the compression stress relaxation factor decreases with time: the higher the temperature, the faster the stress relaxes. Furthermore, the compression permanent deformation increases with time when the temperature is fixed.
