APPLICATION AND PROSPECT OF CaCO3 WHISKER IN COMPOSITE MATERIALS

Calcium carbonate whisker is a new kind of fibrous crystal functional material with high strength, high modulus and excellent thermal stability, which has been highly concerned and applied in many fields. This paper introduces the capability feature of calcium carbonate whisker and its recent progress of the application and research as filler in organic and inorganic compound material field at home and abroad. Application and development prospect of calcium carbonate whisker were analyzed and discussed in several aspects, combining with the new application and preliminary experimental results obtain by the authors. The research indicates that calcium carbonate whiskers have good toughening and reinforcing actions, which endow the materials with new features and functions. Calcium carbonate whisker has important application value, a huge market and broad prospects, which is low-cost, green environment-friendly and conducive to sustainable develop.
