AbstractAdhesive bonding is widely used in automotive production, especially for body assembly. During the manufacturing process, it is critical to be able to measure the strength of adhesive bonds in a nondestructive, effective, and rapid manner. However, there is no current means for inspecting these bonds in real time. This project will apply technique of laser ultrasonics for real-time adhesive bond inspection during body assembly. Laser ultrasonics offers high measurement speed without contacting the part. Phase I demonstrated the feasibility of single-side inspection for mapping the adhesive, and for measuring adhesive thickness and bond strength. Phase II will design and assemble a prototype inspection system, and test it on a full scale auto body. At the conclusion of Phase II, a full specification for a turnkey system will be delivered. Commercial Applications and Other Benefits as described by the awardee: An adhesive bond inspection system would allow greater use of adhesives in auto body manufacture, thereby adding strength and reducing weight.
