Adhesives increasingly being used because they
Increase body stiffness - without significant mass increase
Increase body strength – without significant mass increase
Enable dissimilar materials, e.g. steel + Mg, or composite + steel to be used next to each other
Reduce cost of light-weight materials.
Adhesive bonding is a critical technology
Present in ∼95% of the Mg Front End joints
Present in all the Composite Underbody joints
Allows less expensive sheet product to be used instead of castings or extrusions
Spread strain for more brittle light-weight materials, especially around joints.
