Modeling of Resin Transfer Molding
Resin Transfer Molding (RTM), as a method for the manufacture of advanced ber reinforced composite materials, is attractive because it ooers the possibility of lower manufacturing costs and more complex shapes than traditional methods. A major issue in this new manufacturing process is the elimination of void spaces in the resin ll operation, so that products with high quality are manufactured....
متن کاملParameter Estimation for Resin Transfer Molding
A simplified approach for estimating weld lines, vent locations and fill times for resin transfer molding applications in non-planar geometry is presented. The molding parts are treated as polyhedral spaces for which the concept of Voronoi diagram and shortest paths is utilized to predict the formation of weld lines, location of vents and filling times. The approach is based purely on geometric...
متن کاملDirect Adaptive Control of Resin Transfer Molding
Resin Transfer Molding (RTM) is a manufacturing process that involves injection of liquid resin into a closed mold cavity containing preset fiber mats and a subsequent curing stage. Mold filling is a crucial stage for quality part productions. In order to automate production and minimize the formation of defects, control of mold filling is needed. In this paper, direct adaptive control strategy...
متن کاملMatrix Characterization and Development for the Vacuum Assisted Resin Transfer Molding Process
The curing kinetics and viscosity of an epoxy resin system, SI-ZG-5A, have been characterized for application in the vacuum assisted resin transfer molding (VARTM) process. Impregnation of a typical carbon fiber perform provided the test bed for the characterization. Process simulations were carried out using the process model, COMPRO [8], to examine heat transfer and curing kinetics for a full...
متن کاملInvestigation of Parameters Effect Resin Movement Velocity at Vacuum Assisted Resin Transfer Molding Method (VARTM)
In this paper, Vacuum Assisted Resin Transfer Molding (VARTM) method was simulated by analytical solution. Then the effect of parameters like fiber density, distribution of layer thickness, perform layer thickness, resin viscosity was investigated theoretically. Obtained results show that by selecting optimum distribution layer thickness, increasing fiber volume fraction, reducing viscosity of ...
