What is this about?
Composite materials can deform during curing due to residual stresses from thermal expansion and resin shrinkage. This study combines physics-based modeling, experiments, and AI to predict process-induced deformation (PID) across a range of cure conditions. Deep Operator Networks (DeepONets), transfer learning, and uncertainty quantification are used to improve predictions and optimize cure processes.
Key highlights:
• Developed a DeepONet surrogate model for predicting process-induced-deformation.
• Combined high-fidelity simulations with experimental data using transfer learning.
• Used Ensemble Kalman Inversion (EKI) for uncertainty quantification.
• Predicted degree of cure, viscosity, and deformation throughout manufacturing.
• Optimized cure schedules to reduce residual stresses and deformation.
Why it matters?
Accurately predicting manufacturing-induced deformation can improve dimensional accuracy and reduce costly trial-and-error during composite manufacturing. This AI-enabled framework supports more reliable and efficient cure process optimization.
Relevance to AIM EFRC:
This work advances AIM EFRC's mission to build AI-enabled approaches for understanding the material-process-performance (MP²) relationship in advanced polymer composites. By integrating high-fidelity simulations, targeted experiments, and Deep Operator Networks, the study strengthens the Center's Digital Life Cycle framework for predicting manufacturing behavior and enabling more reliable, energy-efficient composite manufacturing.
