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 کاملN. Modeling and Simulation of Compression Resin Transfer Molding
Accomplishments Analysis of the current modeling approach for CRTM, as well as for some of the physical phenomena involved in the process, such as preform deformation, revealed certain weaknesses in the numerical approach and, more importantly, significant gaps in fundamental understanding of underlying physics. New governing relations for the general Liquid Composite Molding (LCM) and, in part...
متن کاملsimulation of injection molding process including mold filling and compound curing
the present work reports and discusses the results of a 3d simulation of the injection molding process of a rubber compound that includes the mold flling stage and material curing, using the computer code is developed in “udf” part of the fluent 6.3 cae software. the data obtained from a rheometer (mdr 2000) is used to characterize the rubber material in order to fnd the cure model parameters ...
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 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...
