Metal foam offers lightweighting options for automotive


A lightweight metal matrix syntactic foam sandwiched between two carbon fabric layers reportedly offers properties advantageous to the transportation sector such as extreme light weight, flexibility, and the ability to withstand deformation and absorb energy.

The aluminum alloy foam structure was developed by a team led by Nikhil Gupta, a NYU School of Engineering associate professor in the Department of Mechanical and Aerospace Engineering, working with the Deep Springs Technology (Toledo, OH) and the U.S. Army Research Laboratory. They believe that this layered material with a lightweight metal matrix syntactic foam core holds significant potential for automobiles, trains, ships, and other applications requiring lightweight structural components that retain their strength even when bent or compressed.
