Direct Adaptive Control of Resin Transfer Molding
نویسندگان
چکیده
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 is presented for RTM mold filling control in order to account for variations in fiber preform permeability. Using this control strategy, it is shown that the actual filling pattern can successfully be controlled to follow the designed filling pattern.
