Filling inorganic whiskers into composition

A composite material is a multiphase system composed of matrix material and dispersed material. The matrix material is usually a continuous phase, which consolidates the dispersion material such as fiber or particles. The composite material is commonly categorized into the class of materials that the matrix material belongs to metal matrix composites, inorganic nonmetal matrix composites, and polymer-based composites. For example, the metal matrix composite material is a material included in the scope of metallic materials, while the polymer matrix composite material is included in the scope of the polymer material. The inorganic whiskers filled and modified... 

The thermal stability of a material sometimes is represented by the temperature of 5% decomposition and usually can be determined by a thermogravimetric method. Because inorganic fillers have a high melting point, adding inorganic fillers into resin can improve the heat resistance of the polymer. A composite material is prepared by filling calcium carbonate whiskers into PP material. The thermal decomposition temperature (5% decomposition) of the composite material increased from 366.7 to 400.6°C as the whisker content was enhanced. 

The composites can be classified on the basis of the form of their structural components fibrous (composed of fibers in a matrix), laminar (composed of layers of materials), and particulate (composed of particles in a matrix). The particulate class can be further subdivided into flake (flat flakes in a matrix) or skeletal (composed of a continuous skeletal matrix filled by a second material). In general, the reinforcing agent can be either fibrous, powdered, spherical, crystalline, or whiskered and either an organic, inorganic, metallic, or ceramic material.
