Glass transition temperature measurement system |
摘要 |
A glass transition temperature Tg measurement system includes a probe point penetrating into a sample under test that has been heated by a heater to a temperature where the sample undergoes a phase change from a solid to a semisolid. A thermocouple is used to measure the temperature while a motion transducer is used to measure the amount of penetration. The penetration amount sharply increases at the glass transition temperature. A portable unit can be used in the field to test the Tg properties of various composite materials used, for example, in structures including buildings and bridges. |
