Conch Shells Inspire Next Generation Helmets, Body Armor

New submitter omaha393 writes: Researchers at MIT used a 3D printing approach to develop a biomimetic composite capable of withstanding 70-85% more resistance than typical helmet designs. The material was manufactured using a composite of hard and soft printable polymers called VeroMagenta and TangoBlackPlus. The polymers were printed to overlay in a specific pattern that mimics conch shell molecular hierarchy, thus preventing cracks from spreading and offering a substantially more crack-resistant material. The researchers propose the material can be custom tailored and readily printed for future helmets and body armor manufacturing. The study has been published in Advanced Materials.
