Resin Radial and Isothermal Infiltration in Fibrous Media: A New Mathematical Formulation

Abstract:

The objective of this work is to describe the fluid flow in porous media including the sorption term of the fluid by the fibers. The study has been applied to the manufacture of fiber-reinforced polymer composites by resin transfer molding, giving emphasis to radial resin infiltration in a one-dimensional approach. The mass conservation equation and Darcy’s law are presented and the solution of the governing equation is obtained. The advanced mathematical modeling includes the effect of fluid sorption by the porous media. Predicted flow front results and resin pressure fields within the mold during the injection process are presented, and the effects of the sorption term, injection pressure and fibrous medium permeability analyzed.
