Ultralight Material Withstands Supersonic Microparticle Impacts
Looking like it’s straight out of a Purple mattress commercial, MIT researchers show “nanoarchitected” materials that could be tough, lightweight armor similar to Kevlar and steel.
The researchers have fabricated an ultralight material made from nanometer-scale carbon struts that give the material toughness and mechanical robustness. The team tested the material’s resilience by shooting it with microparticles at supersonic speeds, and found that the material, which is thinner than the width of a human hair, prevented the miniature projectiles from tearing through it.
The researchers calculate that compared with steel, Kevlar, aluminum, and other impact-resistant materials of comparable weight, the new material is more efficient at absorbing impacts.
