Development of a Reliability-Based Method of Service Life Prediction for Sealant

Abstract

Standard test methods, such as ASTM C719, evaluate sealant performance though threshold test measurements. This method and its derivatives do not offer reliable predictions of in-service performance. This article will detail efforts to move away from the use of threshold tests towards a reliability-based method for predicting the service life of sealant materials. The central role of dose-damage based models in this approach is explained. The first task is designing a method to monitor the damage to a sealant through changes in the mechanical properties. Changes in the cross-link density of a sealant are monitored during cure by measuring changes in the tensile modulus.
