3. Inorganic whisker reinforcement

Whisker is a fiber with extremely small diameter grown in the form of single crystal under special conditions. It has a highly ordered atomic arrangement structure, so it can approach the theoretical strength of the valence bond between atoms, and has great potential for reinforcing epoxy adhesives. Available whiskers include zinc oxide whiskers, calcium sulfate whiskers, calcium carbonate whiskers, aluminum borate whiskers, titanium-based whiskers, hydroxyapatite whiskers, magnesium hydroxide whiskers, basic magnesium sulfate whiskers, silicon carbide whiskers, etc.
