Parameter 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 کاملOn-line Characterization of Bulk Permeability and Race-tracking During the Filling Stage in Resin Transfer Molding Process
Resin Transfer Molding (RTM) is widely used to manufacture polymer composite materials. In this process, the fiber preform is placed in a closed mold and thermoset resin is injected to saturate the preform. After the resin cures the mold is opened and the net shape composite part is obtained. With RTM, one is capable of making complex and high quality composite parts with short cycle times. How...
متن کاملModeling 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 کاملModel-Assisted Control of Flow Front in Resin Transfer Molding Based on Real-Time Estimation of Permeability/Porosity Ratio
Resin transfer molding (RTM) is a popular manufacturing technique that produces fiber reinforced polymer (FRP) composites. In this paper, a model-assisted flow front control system is developed based on real-time estimation of permeability/porosity ratio using the information acquired by a visualization system. In the proposed control system, a radial basis function (RBF) network meta-model is ...
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...
