Abstract:With the growing needs of prepreg tapes for the automated fiber placement (AFP), the deviation-rectifying of prepreg in slitting process was investigated on a self-developed 16-tow prepreg slitting and winding machine. The process of slitting and rewinding of prepreg tape was introduced, and the reason of prepreg tape deviation in slitting process was analyzed. In order to ensure the quality of the narrow prepreg slits, the application of the fuzzy PID algorithm in a closed-loop control system was discussed. A fuzzy PID algorithm was designed by combining fuzzy rules and PID controller. By applying it to precise deviation-rectifying control strategy, the automatic control of rectification could be achieved with accuracy of 0.1 mm, which satisfies the requirement of the prepreg tape both in slitting quality and layup quality for AFP. © 2018, Editorial Department of Transactions of NUAA.
