采用差示扫描量热法(DSC)研究了PA6/硅灰石纤维复合材料的非等温结晶行为,分别采用Jeziorny法、Ozawa法和Mo法对非等温结晶动力学进行了分析,经过计算得到相应的非等温结晶动力学参数。结果表明:复合材料的结晶分为初期结晶阶段和二次结晶阶段,随着降温速率的增大,结晶温度降低,结晶温度范围变大,结晶速率增大。Jeziorny法和Mo法能较好地描述复合材料的非等温结晶过程,而Ozawa法不适合描述该过程。
The non-isothermal crystallization behavior of PA6 / wollastonite fiber composites was studied by differential scanning calorimetry (DSC). The non-isothermal crystallization kinetics of PA6 / wollastonite composites were analyzed by Jeziorny method, Ozawa method and Mo method respectively. Correspondingly, Non-isothermal crystallization kinetics parameters. The results show that the crystallization of the composites is divided into the initial crystallization stage and the secondary crystallization stage. As the cooling rate increases, the crystallization temperature decreases and the crystallization temperature increases, and the crystallization rate increases. The Jeziorny method and the Mo method can well describe the non-isothermal crystallization process of the composites, while the Ozawa method is not suitable for describing the process.
