Durable Multi-Material Group I Adhesive Joints

NCMS Project #: 140968

Problem: The development of Group 1 adhesive systems that have both characteristics is significant and warrants further development to classify the performance characteristics of these systems. These Group 1 adhesive systems need to be evaluated relative to the joint configurations and types of materials they are expected to bond together so that the performance characteristics can be determined for actual integration into future or existing ground vehicle environments.

Benefit: Corrosion due to the joining of dissimilar metals is a multi-billion-dollar problem as well as a safety hazard. Commercial airlines, shipping, railway systems, and trucks all lose countless maintenance and sustainment hours and incur high replacement costs due to corrosion. This group of adhesives could drastically reduce that expense.

Solution/Approach: The Group 1 adhesive systems need to be evaluated relative to the joint configurations and types of materials they are expected to bond together so that the performance characteristics can be determined for actual integration into future or existing ground vehicle environments. Project team will evaluate a range of physical structural joint configurations backed up by modeling and simulation of each configurations. These joint configurations will ultimately be developed and bonded together with low temperature cure high strain capable adhesive system, high temperature cure high strain capable adhesive system, and a low temperature cure elastomeric adhesive system, which will be validated.
