摘要：
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". © 2020, Editorial Office of Chinese Journal of Materials Research.
