ASTM D7028 Standard Test Method for Glass Transition Temperature (DMA Tg) of Polymer Matrix Composites by Dynamic Mechanical Analysis (DMA)

ASTM D7028用動態(tài)力學分析法 (DMA) 測定聚合物基復合材料的玻璃化轉變溫度 (DMA Tg) 的標準試驗方法

?

適用范圍

Scope:

This test method covers the procedure for the determination of the dry or wet (moisture conditioned) glass transition temperature (T g ) of polymer matrix composites containing high-modulus, 20 GPa (> 3 × 10 6 psi), fibers using a dynamic mechanical analyzer (DMA) under flexural oscillation mode, which is a specific subset of the Dynamic Mechanical Analysis (DMA) method.
