Research Overview

The scientific goals of this cooperative research effort are:

​

  • To unravel the fundamental underpinnings of the MP2 relationship via constructing an uncertainty-aware multi-objective “Digital Life Cycle” (DLC) that represents a suite of seamlessly linked, experimentally converged, high-fidelity models embracing all stages of a composite component’s life cycle, linking perceived risk from energy consumption to carbon footprint.

​

  • To leverage physics-informed AI models and build microservice-based cloud tools to enable inverse composites material architecture and manufacturing process design and in situ diagnosis and control.

​

  • To inform and validate the DLC and AI models and implement new material and process designs by exploiting innovative material engineering, characterization, and testing methods.

Research Approach

The center's scientific goals will be achieved via iterative efforts of three research thrusts shown above. Research Thrust I is the DLC representing a suite of seamlessly linked, high-fidelity multiscale models for simulating all stages of a polymer composite’s life cycle, which also integrates uncertainty and E3 impact quantification. The DLC will enable the generation of a large quantity of high-fidelity data to train AI models. Research Thrust II is the AI modeling and inverse design research thrust, in which we develop new AI models, including physical informed neural networks (PINN) and multiscale deep neural operators (DeepONet), to efficiently map the composite materials’ architecture and the manufacturing process to composite components’ performance. Next, we develop a conditional VAE neural network (MaterialVAE) for material inverse design and a conditional VAEGAN neural network (ProcessGAN) for manufacturing process design. By utilizing the experimental facility and capabilities at the Clemson Composites Center, the Center for Manufacturing Innovation at the University of Florida, the Pacific Northwest National Laboratory (PNNL), and other relevant BES facilities and infrastructure, in Research Thrust III, we conduct material characterization and testing of mechanical, physical, rheological, and morphological properties at nano-, micro-, and macroscales to inform and validate both DLC and AI models and simulations. We will also implement new/hybrid processes that combine existing or new scalable processing routes to create tailored composite micro and macro structures. Finally, the inverse design is performed by the generative AI models to obtain a holist solution of optimal composite material and its manufacturing process.

Synergy

The EFRC program is not a simple conglomeration of all the expertise and resources. While the research team is grouped into DLC, AI and Experiments research thrusts according to their functions, the scientific goals will be achieved through the collaboration of the research thrusts. Each research thrust not only provides information to but also validates results for the other two. The three research thrusts form an iterative loop and the iteration among them continues until all three produce consistent results and thus the research has converged. Therefore, combining all the expertise and capabilities of the team together, and with this helical collaborative iteration, we believe the scientific challenges can be addressed and the overarching goal of the project can be reached.
