Abstract
The purpose of the present study is to outline a procedure for determining the spatial variation in the viscosity and therefore to predict the consolidation rates during non-isothermal squeeze-flow processes. The viscosity and the flow profile depend on the temperature variation within the prepreg in a complex manner. For instance, even when the axial temperature distribution is uniform, the viscosity distribution is not because the thermal histories of the fluid elements at different axial positions are different. This viscosity distribution and the flow profile can be determined by evaluating the trajectory of each fluid element for selected temperature distributions. In addition to its relevance to the flow during lamination, the present study may also be applicable to other non-isothermal processes such as compression or rotational molding.
