Technical Barriers

  • 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.
