Flow Front Analysis In Resin Infusion Process

The Resin Infusion under Flexible Tool (RIFT) is a closed mould technology to manufacture composite material and particularly large component. This work concerns the analysis of impregnating flow of a thermosetting resin in a RIFT process and the simulation of the process for the manufacturing of the laminate of simple geometry. Starting from the analysis of the impregnating flow, an analytical model based on the electrical analogy has been developed to calculate the value of an equivalent permeability of the fibrous reinforcement. The value of this parameter is requested
to realize the process in simulation by FEM. The results of the simulations have been compared with the results obtained by experimental tests carried out using a preform of fiber glass reinforcement and epoxy resin to manifacture plane laminate in composite materials.

Hello authors,
the analytical model could study the impregnating process without FEM help?
Thanks for your attention, Theodor

Hello Theodor, I am one of the authors, my name is Umberto.
When the geometry of the laminate is simple the analytical model is enough to investigate the process, but with complex geometry the analytical formula isn't easy, so it need use a FEM program calculating the equivalent permeability of the system preform-distributor by the analytical model based on the electrical analogy.
