Composite Material Glass Transition Temperature (Tg) Property (Part 1)

摘要

Composite structural design depends heavily upon the temperature, humidity-moisture environment that the structural application must survive during its anticipated operational lifetime. Fatigue, vibration and many other operational loading requirements will also affect the design and material selections. For this Tech Tidbits topic, the author has selected the glass transition temperature (Tg) as an area to discuss with respect to test methods available and the impact of temperature and moisture. The topic will be discussed in various stages over the next several issues of the SAMPE Journal in various parts. This part will establish some reference materials important to understanding test methods available and provide background reading.
