| 摘 要： | 运用热变形温度(HDT)、示差扫描量热(DSC)和动态热机械分析(DMA)方法对不同热固性树脂固化体系的耐热性能进行了测试,并分析了测试结果差异与其物理机制的关系。结果表明:通过DMA图谱中模量曲线拐点得到的热固性树脂耐热温度,与材料的热变形温度比较吻合。从DMA图谱中得到的玻璃化转变温度比DSC曲线得到的稍低。

| Abstract: | The heat-resistance properties of different thermosetting resin cured systems were measured by heat distortion temperature method(HDT),differential scanning calorimetry(DSC) and dynamic mechanical analysis(DMA).The differences of the measured results were analyzed as well as the relationship between the heat-resistance properties and the physical mechanism of the measured method.The results showed that the heat-resistance temperature obtained by the inflexion of modulus curve in DMA spectrums was anastomosed with the heat distortion temperature.The peak temperature of the dissipation curve in DMA spectrums was a little lower than the glass transition temperature by DSC. |
