Composite Metal Foam Outperforms Aluminum

Oct-21-19 A composite metal foam infused with resin could outperform the aluminum typically used in airplane wings.

The composite metal foam (called infused CMF) was created by a team from North Carolina State University by infusing a steel-steel CMF made up of stainless steel hollow spheres and a stainless steel matrix with a hydrophobic epoxy resin. The resin fills about 88 percent of the CMF’s pores, resulting in a material that sheds water, repels insect residue, and resists degradation from abrasion better than aluminum while also weighing much less.
