摘要:

使用热重分析仪测定尼龙66(PA66)和两种不同玻纤增强尼龙66复合材料(GF/PA)的热分解曲线，用Kissinger法和Crane法研究了PA66和GF/PA的热分解动力学。结果表明:PA66、GF/PA-1和GF/PA-2的热分解反应级数分别为0.949、0.912和0.921，表明均为一阶热分解过程；热分解活化能分别为218.65 kJ/mol、121.81 kJ/mol和132.23 kJ/mol，表明玻纤的加入显著降低了PA66的热分解活化能。在加热速率相同的条件下两种GF/PA达到最大热分解速率的温度都比PA66的低，表明玻纤虽然改善了PA66的性能，但是加快了PA66的热分解过程，说明存在着“灯芯效应”。

Abstract：

The thermal decomposition curves of nylon 66 (PA66) and two kinds of glass fiber reinforced nylon 66 composites (GF/PA) were measured by thermogravimetric analyzer, and the thermal decomposition kinetics of PA66 and GF/PA were investigated by the Kissinger method and Crane method. The results showed that the thermal decomposition reaction order of PA66, GF/PA-1 and GF/PA-2 were 0.949, 0.912 and 0.921, respectively, which were all consistent with first-order reactions with thermal decomposition activation energy of 218.65 kJ/mol, 121.81 kJ/mol and 132.23 kJ/mol, respectively. These results demonstrated that the incorporation of glass fiber reduced the thermal decomposition activation energy of PA66. In addition, by the same heating rate, the temperature corresponding to the maximum thermal decomposition rate for the two kinds of GF/PA was obviously lower than that for PA66, indicating that although glass fiber improved the performance of PA66, but accelerated the thermal decomposition process of PA66, and there was also a "wick effect".
