Composites are normally composed of matrix materials and reinforcement materials, and each component material has an obvious interface with the macroscopic “anisotropy” characteristic. According to the properties of matrix materials, composites can be divided into metal matrix composites, inorganic nonmetal matrix composites and organic (resin-based) matrix composites. The basic properties of polymer composites are mainly determined by the matrix material, while the mechanical properties are mainly determined by the properties, dosage and laying mode of the reinforced fibers. And the reasonable molding process can make the excellent properties of the matrix material and the reinforcing material fully show in the composites.

Designability of performance

Conventional materials have relatively fixed properties due to their fixed material composition, while thermosetting composites have no specific material composition, so they have no fixed properties. In practice, the matrix material, reinforcing material and forming process are often selected according to the requirements of the properties and shapes of the materials. In other words, the properties of composite materials can be designed. Due to the performance of the composite materials can be designed, which make its application range very wide, for example, it can be designed according to the requirement of the environmental conditions such as anti-corrosion, insulation and pervious to light material, can also be designed according to the functional requirements of lightweight, high strength, insulation, conductive, wave, affected wear-resistant materials such as absorption, and can respond to the external environment change of “sharp” composites.

Unrestriction of structure shape:
The molding process of thermosetting composites is different from that of traditional materials such as steel and wood. By using the resin modification technology and processing technology of thermosetting composite materials, the composites with excellent high temperature resistance and fire resistance and the components satisfying the structural performance can be designed.
