Effect of Moisture on Mechanical Behaviour of Polymer by Experiments

Abstract

The effect of moisture content on mechanical behavior of polymer materials is experimentally investigated in this paper. In particular, nylon-6 is selected as testing samples, which were studied by an effective experimental technique called digital marker correction. An equivalent relationship between time intervals and the moisture content for polymer nylon-6 has been obtained based on the experimental observation and results. The generalized curves for the time versus moisture contents of nylon-6 are obtained and then the approximate equation of shift factor is presented in this paper.
