A Rapid Method of Measuring the Glass Transition Temperature Using a Novel Dynamic Mechanical Analysis Method

摘要

This paper describes a method of measuring the glass transition temperature, by dynamic mechanical analysis, in which the glass transition temperature can be obtained by determining the temperature at which the peak value of damping is observed. The novelty of the method reported here is to use a fast heating technique with a feedback circuit that maintains the specimen at resonance. By doing the test in about a minute, polymer cure is not altered significantly by the heating cycle.
