Abstract
The present research aims at studying the kinetics of non-isothermal crystallization of the polyamide 66 matrix and its
composites with the presence of a glass fiber load. To achieve that goal, the non-isothermal crystallization of polyamide
66 has been studied by means of DSC. The ratio of tested reinforcement varies from 7% to 50% of glass fiber in mass.
The modeling, by the theories of Jeziorny and those of Mo, has allowed us to study the influence of adding this
reinforcement, as well as the variation of the rate of cooling, on the kinetics of crystallization of the composites in
question, which has been manifested by a remarkable change in the nucleation mechanism of the polyamide 66 matrix.
Regarding the reinforcement effect, the incorporation of the glass fibers load into the polyamide 66 matrix has caused
the appearance of exothermic peaks in a higher temperature range and that for all the working materials. Finally, the
results showed that the Mo model is the most suitable for the study of polyamide 66/glass fiber crystallization kinetics.
