Creating lighter, faster, and more fuel-efficient vehicles is not a challenge that’s unique to boatbuilding and sometimes technological advances from other industries find their way into ours. One such technology is a new lightweight aluminum “foam” being developed by German engineers to be used in a high-speed train.
The material—two pieces of aluminum sandwiched on either side of a composite made of magnesium, silicon, copper, and aluminum—is said to be 20 percent lighter than traditional fiberglass.
Extensive crash testing by the engineers at the Fraunhofer Institute and Voith Engineering Services show that this material provides better protection in the event of a crash than fiberglass.
Time will tell if this material finds its way into the marine market, but if it does, you heard it here first.
