In May of 2000, ASTM Committee E-37 on Thermal Measurements sponsored the symposium Materials Characterization by Dynamic and Modulated Thermal Analytical Techniques. This STP contains papers presented at that symposium.
Major contributions to the study of material physical and chemical changes are presented in this publication. The innovative approaches to scanning calorimetry, modulated temperature DSC (MTDSC) techniques, can distinguish a polymer glass transition temperature, Tg, from other overlapping thermal-physical properties and events. The window of measurement has been expanded for better sensitivity and higher resolution. A number of presenters/authors studied the factors influencing the Tg, such as the heating rate, modulation frequency or period, amplitude of the imposed wave, as well as the type of dynamic or modulated curve.
Specific topics covered by papers in these proceedings include:
- thermomechanical analysis (TMA)
- experimental variables and calibration
- glass-rubber transition
- melting of polymers
- differential scanning calorimetry
- thermogravimetry
- simultaneous dynamic mechanical and dielectric measurements
- electrochemical impedance spectroscopy (EIS)
- curing analysis
- dielectric thermal analysis (DETA)
- cyclic voltammetry (CV)
- modulated temperatiure differential scanning calorimetry (MTDSC)
- cyanate ester
- bismaleimide
- dynamic mechanical properties of polymer composites
- crystallization
- vitrification
- devitrification
- fiber-reinforced epoxy
- observed glass transitions
- dynamic differential scanning calorimetry (DDSC)
Whether you are working to develop new test methods, need to understand the basis for test results, or are looking for general background information on composite and polymer materials testing, this STP provides accurate, useful information for researchers, engineers, and scientists.
