Abstract: The static and dynamic nano-mechanical properties of the keratinous of cattle horns were investigated to show the gradient distribution of the hardness and moduli on the cross section and longitudinal section. The variation of the dynamic storage moduli and loss moduli under the different load and frequency were discussed. The results will be useful to study the biological function of the cattle horn.

Key words: biological engineering, keratinous, cattle horns, static nano-mechanical property, dynamic nano-mechanical property
