A general model for the prediction of the rheological behavior of epoxy resins during the processing of epoxy based laminates is presented. The model is able to predict the temperature and the extent of reaction across the laminate thickness during processing. The model leads the computation of the viscosity inside the composite where experimental measurements are not possible. Thermal characterization of the reacting systems gives the input data necessary for the mathematical modelling. The numerical simulation has confirmed the necessity of a controlled temperature ramp in order to obtain a more homogeneous laminated structure. Moreover, the numerical results indicated that the process variables may present anomalous behavior which may affect the physical properties and durability of the final product.
