Application of hyperfine Sic Whisker in National defense:
1, Improved armor, bearing and engine burners.
2, High-performance radar antenna materials.
3, Infrared ray rectifier.
4, Low visibility components.
5, Helicopter and jet aircraft's components.

Sic whiksers are nearly single crystals, the whiskers typically have very high tensile strengths, elastic modulus and enganced strengths, and used for metal matrix, ceramic matrix, macromolecule polymer matrix, and so on.
