New NSF center to use analytics, AI to modernize how manufacturers repair composites

Composites and hybrid materials will define the future of manufacturing – and with good reason: These strong yet lightweight materials that comprise half of all commercial twin-aisle airplanes and most electrical vehicles are lighter and more fuel efficient, lessening their carbon footprint.

However, because composites are unique (combining different materials), it is difficult to model how they will degrade and fail during use. Also, impact damage may not be visible or may be barely visible, making it harder to detect than damage to metallic structures. Furthermore, repairing these materials and structures is both time-consuming and expensive due to the complexity of composite parts and lack of experience or knowledge and data.

Based at the Georgia Institute of Technology, the Center for Composite and Hybrid Materials Interfacing (CHMI) intends to dramatically improve how composite and hybrid structures are joined and repaired. The Center is one of four active NSF Industry/University Cooperative Research Centers (IUCRCs) at Georgia Tech.
