When Data-efficient Machine Learning Comes to the Rescue: An AI-based Optimization Framework for Advanced Manufacturing.
Abbas S. Milani, Ph.D., P.Eng. | The University of British Columbia
Milad Ramezankhani | The University of British Columbia
Monday April 17, 2023 | 9:00 AM - 12:00 PM
This tutorial will first present and mutually discuss the current technological burdens in the successful application of machine learning in advanced manufacturing settings, with a focus on composites. It will then introduce a range of data-efficient models, namely, transfer learning, multi-fidelity learning and physics-informed machine learning, and review the emerging application of such models in a few smart manufacturing case studies conducted at research scale. By the end of this tutorial, the attendees will be able to: •Identify the root causes of machine learning’s poor performance in advanced manufacturing; •Design a data-efficient learning platform for prediction and optimization tasks in manufacturing scenarios; •Develop a simple transfer learning framework in Python for a composites autoclave processing case study.
The Macro Fiber Composite (MFC) – a piezo ceramic composite patch actuator and sensor
Thomas P. Daue | Smart Materials
Monday April 17, 2023 | 9:00 AM - 12:00 PM
The MFC or Macro Fiber Composite was invented at NASA Langley Research Center during the end of the 90’s. Smart Material Corp. began to commercialize the MFC under an exclusive US government license in 2003. The MFC is a member of the family of Low Profile Actuators, often called Patch actuators and is based on piezo ceramic fibers. Due to its excellent properties like flexibility, anisotropy, robustness and long-term stability, the Macro Fiber Composite is used as an actuator, as a sensor and as a kinetic energy harvester today. A large body of application know how, reliability tests and performance data are available for the MFC. More than 1,600 publications of academic, company and government research facilities are publicly accessible. This tutorial will give an overview of the capabilities of the MFC, its history, including other patch actuator developments and three selected case examples of its application.
Ablation Science, Technology, and Applications
Joseph Koo | University of Texas
Monday April 17, 2023 | 1:00 PM - 4:00 PM
This 3-hr tutorial presents a solid introduction of “Ablation Science and Technology” with aerospace and defense applications. Useful to material scientists, chemists, physicists, and research engineers who are new to “ablation science and technology” and to existing engineers/scientists who wish to expand their experience to new experimental and numerical techniques. Topics covered include (a) traditional and nanocomposite ablatives for thermal protection systems (TPS) and solid rocket motors (SRM) materials processing and manufacturing, (b) in-situ ablation recession and thermal sensing, (c) ablative char strength sensing, (d) aerothermal ablation test and evaluation, (e) material thermophysical properties characterization, (f) material response ablation modeling, and (g) microstructures 3D analysis and properties modeling.
Recycling Polymer Composites: Current and Emerging Materials and Processes
John Misasi, PhD | Western Washington University
Monday April 17, 2023 | 1:00 PM - 4:00 PM
This tutorial will provide an overview of material and process technologies in the evolving field of composites recycling. Attendees will learn about the following: (i) primary recycling methods for composites and material-specific recycling processes, (ii) recycled composite materials and recycling’s impacts on their properties, (iii) materials enabling improved composites recycling and the circular economy, (iv) applications of recycled composite materials. By the end of this session attendees will have a better understanding of both commercially-available and emerging recycling processes, and the materials they create. The session will be of interest to those with a working knowledge of composite materials and manufacturing processes looking to gain a better understanding of the end-of-life options for these critical, high embodied energy materials.
