Abstract
The crystallization behavior of glass fiber reinforced PA66 composites was characterized using DSC. Parameters of isothermal and non-isothermal crystallization kinetics were calculated using of Mo and Kissinger methods. It showed that glass fiber played as a heterogeneous nucleating agent, which increased the crystallization rate of PA66. When the glass fiber content was 30 %, the crystallization rate reached the maximum. The greater the cooling rate, the greater the degree of crystallinity. The crystallization activation energy of the composites were -297. 22, -356. 32, -481. 00, and -365. 59 kJ/mol, respectively, when the glass fiber contents were 0, 15%, 30 %, and 45%.关键词
