Optimization of carbon fiber patch end-effector design and research on reduced order models for digital twins
Abstract
Fiber patch placement technology automates the production of complex fiber composite structures. This study tackles issues such as uneven pressure during carbon fiber patch placement, which reduces interlaminar shear strength, and the high cost of monitoring end-effector states. A specialized end-effector was designed to improve pressure uniformity. Using simulation data and singular value decomposition, a real-time digital twin reduced-order model (ROM) was developed for state monitoring. An actuator with five evenly spaced airway holes demonstrated optimal pressure distribution. Experimental validation showed less than 10% error relative to simulations, confirming both finite element accuracy and the reliability of the digital twin model.
