VIBRATION RESISTANT MATERIALS BEING DESIGNED TO MIMIC TOOTH ENAMEL

VIBRATION RESISTANT MATERIALS BEING DESIGNED TO MIMIC TOOTH ENAMEL  dentist Albuquerque

University of Michigan research on building materials that can withstand vibration and stress came up with a perfect model: tooth enamel.

Soft materials absorb stress and vibration very well, but cannot be used to make structures like airplane fuselages and computer motherboards.  Rigid materials like steel and titanium are very strong, but vibration and stress over long periods of time can cause failure of the material.

In studying animal structures that hold up for decades under vibration and/or stress, the ideal material appeared to be tooth enamel.  Many organs and tissues in vertebrate bodies have evolved over millennia to try to improve on performance.  Tooth enamel, however has remained unchanged in a wide variety of animals over eons because the design has worked out so well.

Enamel is made of ceramic crystal columns bonded together with an organic matrix, set up in a hard protective covering.  This bonding of materials gives this resilience not seen in much harder substances.

The research at the University of Michigan mimicked the tooth enamel by growing zinc oxide nanowires on a chip then layered them with a polymer and baked the result.  The process is replicated thousands of times, linking the wire/polymer structures to form a solid sheet.The researchers showed that this structure duplicated some of the vibration-resistant characteristics of the tooth enamel.

This is a very pains-taking process, but one that researchers feel can eventually be refined to produce similar materials for industrial use, like cars, airplanes, and bicycles.
