Description
Antai Ren, Teng Zhang, Tao An, and Liying Ma present a 2026 engineering study on repairing holed aluminum plates with glue plus rivets. Perforations slash a plate's load capacity, and hybrid repairs share the load between adhesive and rivets. What was missing was a quantitative recipe matching hole size, rivet strength, and adhesive strength. The team derived a strength-matching rule and a way to estimate the repaired plate's remaining strength.
They tested two aerospace epoxies of differing strength against rivets of differing capacity, in strong-glue and weak-glue pairings. Lab pulls, camera-based strain mapping, and simulations agreed closely, within about five percent on failure loads. Before failing, the adhesive carried up to two-thirds of the transferred load. All six repair designs recovered at least three-quarters of the original strength. The authors propose their model for design use, while noting broader validation is still needed.
