Flow Modelling of Thermosetting Resins Through Porous Medium of A Composite Structure


Abstract:
Mathematical modeling of resin flow into the cavity of the mold is a very complex problem due to the porous medium realized by reinforced material. The paper is presented the start evolution and the velocity of the flow for the polyester resin thermosetting in the molding process of the composite plate through „Resin Transfer Molding” (R.T.M.) procedure. Considering an elementary volume dV, the following were determined: friction forces in porous medium, elementary mechanical work dL, and power P in injection process. At the end, the equation of the fluid flow rate u(x,y,z) was established and graphical represented using MATHCAD program. Resin flow modeling and simulation allows the optimum choice of the injection point in the case of complex parts. The validation of a theoretical model was established by the experimental tests. Keywords: resin, composite, friction, flow, fluid
