ASTM D7028
标准名称
ASTM D7028 Standard Test Method for Glass Transition Temperature (DMA Tg) of Polymer Matrix Composites by Dynamic Mechanical Analysis (DMA)
ASTM D7028用动态力学分析法 (DMA) 测定聚合物基复合材料的玻璃化转变温度 (DMA Tg) 的标准试验方法
适用范围
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.
