摘要：

The crosslinking mechanisms and kinetics of carbon fibre (four samples) and glass fibre (five samples) reinforced epoxy formulations subjected to various treatments were studied by H-1 and C-13 nuclear magnetic resonance spectroscopy (liquid and solid cross-polarization/magic-angle spinning) and Fourier-transform infrared spectroscopy, differential scanning calorimetry, high-performance liquid chromatography and Calvet microcalorimetry. By comparison with the results obtained in previous work on pure matrices, it was shown that the presence of fibres does not change the reaction mechanisms or the network structure. On the other hand, it was possible to show that the nature of the fibre reinforcement, the various treatments undergone, the formulation and heat cycles led to notable differences in the reaction rate, particularly at low temperature.
