Abstract

Hybrid fastening system that uses an adhesive insert as a structural element has been shown to eliminate bolt-adherend-slip, reduce delamination, and produce peak loads that are 200% to 500% greater than slip-loads in conventional mechanically fastened joints, while still allowing versatility in joint design. These improvements were experimentally obtained for similar substrates with a constant diameter bolt/hole. The efficiency of hybrid fastening systems with varying bolt diameter and dissimilar substrates have not been studied or fully characterized.
