Michigan Engineering researchers have developed a rigid and durable new material inspired by tooth enamel.
Unavoidable vibrations, such as those on an airplane, cause rigid structures to age and crack, but most materials that effectively absorb vibrations are soft, so they don’t make good structural components, like beams, chassis or motherboards. Researchers chose to model their new material after enamel because it is strong and rigid, but also effectively absorbs vibrations.
The research for this new material is presented in the paper, “Abiotic tooth enamel,” in the journal Nature.
