VTO research and development on joining of dissimilar lightweight materials

As more manufacturers work to transition their vehicles to EVs, the need for better joining technologies and packaging solutions which aid in both increasing efficiency via light-weighting solutions as well as focus on crash worthiness are critical. The Materials Technology Program oversees a multi-lab effort to build upon knowledge gained during the first two phases of the Joining Core Program. Projects will continue to conduct research and development on joining of dissimilar lightweight materials, including advanced high strength steel, aluminum, polymer matrix composites, and magnesium with the focus on transitioning these methods into a high volume, low cost manufacturing environment. In addition, extending the work on joining dissimilar materials to include the use of sustainable material in researching and developing new joining methods and addressing the subsequent issue of corrosion when joining dissimilar materials.
