Lightweight technology has long been and is sure to remain a mainstay of automotive and aerospace engineering, shipbuilding and a host of other industries. Lighter materials and components could also help cut emissions that drive climate change. But lighter options are pricier, and the relatively steep cost has impeded their adoption. That is about to change thanks to the efforts of a consortium of automakers, suppliers and research institutes. Called ALLIANCE and coordinated by Daimler and the Fraunhofer Institute for Structural Durability and System Reliability LBF, this project has some good news for designers: As it turns out, it is entirely possible to build components that are up to 33 percent lighter at an added cost of less than three euros per kilogram-saved.
