Forming a strong bond

Multi-material vehicles are becoming more prevalent as automakers attempt to reduce vehicle weight and boost fuel efficiency. Selecting the proper adhesive is critical when bonding dissimilar materials.

Lightweighting in automotive design is currently a major trend. This initiative is driven by the need to improve the fuel efficiency of vehicles to meet stricter upcoming regulations. Even so, the challenge remains to ensure optimum mechanical, NVH, and crash-safety performance while designing lightweight components.

When designing lightweight components and assemblies, it has become more common to design them as “hybrid structures” that make use of multi-materials. Use of structural adhesives for joining different materials is beneficial for several reasons.
