Abstract
Rubber materials are indispensable in various industrial environments. However, it is very difficult to predict the physical properties and life of rubber materials depending on their usage environment. Physical properties begin to deteriorate owing to chemical changes even when rubber materials are not used. Despite this deterioration, they can be used within a range that does not impair safety or performance. In this study, rubber specimens made of NR65 natural rubber were first deteriorated at 80℃ for one week and one month, respectively. Next, the stress relaxations of three groups of specimens were observed at various elongation conditions (50%, 100%, and 150%). An inverse power model for predicting life was derived from the experimental results. Finally, life at a relatively low elongation condition (30%) was predicted and validated by comparison.
