Proposed Model

In this study, three relevant friction ‎forces: constant friction force, hydrodynamic friction force and coulomb friction force are ‎considered between sheet molding compound (SMC) charge and contact surface of the mold. The power ‎law model is implemented to propose a model for prediction of hydrodynamic friction as the dominant friction of the SMC compression molding. The proposed model ‎is simple and does not need any extra experimental parameters. Finally, a model has been developed to predict the molding pressure under non-isothermal conditions. The obtained results of the model are in a very good agreement with the experimental data.

Based on generalized Hele-Shaw(GHS) model, numerical simulation of compression-molding flow of sheet molding compound (SMC) in complicated dies is realized by control volume/finite element method (CV/FEM). Finite element computing and post analysis programs have been written. The flow fronts of SMC charge during compression molding are tracked, and the time needed of mold filling in complicated dies is predicted. The results of simulation are helpful for the placement of SMC charge, the design of mold and the optimization of technological parameters.
