The researchers recognized how the complex arrangement of the material influences its mechanical properties. A hierarchical structure of materials of different hardness is the basic secret behind the performance of enamel. The more crosslinked these ingredients are, the more stable the substance is. Sabine Bechtle, who was instrumental in the research project, raves about the aesthetic structure of enamel. Under magnification of 10, 000 times, the cross-section of the enamel first shows individual fibers. The next layer is followed by fiber bundles and, finally, a wickerwork of fine fibrous tissue on the micro level. "We found that the highest stiffness and strength is found at the nanoscale, " says Bechtle.
High load-bearing capacity of materials is very much in demand in technology. Following the example of nature, humans can develop enormously high-performance materials. The scientists therefore see their discovery as a basis for the development of synthetic materials.Gerold Schneider (Hamburg University of Technology) et al .: Press release of the Technical University of Hamburg-Harburg ddp / science.de?
