1. the structure of composite material: structure, mainly used as load bearing structure of the composite material reinforced by can bear load group yuan (such as glass, ceramics, carbon, polymer, metal, natural fiber, fabric, whisker, sheet and particles, etc.) and can enhance the body become whole material force at the same time, the function of matrix components (such as resin, metal, ceramics, glass, carbon and cement, etc.). The structural materials are usually divided into polymer matrix composites, metal matrix composites, ceramic matrix composites, carbon-based composite materials and cement composite materials.

2. Functional composites: functional materials are composite materials that provide other physical, chemical and biological properties besides mechanical properties. Including piezoelectric, electric conduction, radar stealth, permanent magnetism, photochromism, sound absorption, flame retardant, biological self-absorption and other kinds of composite materials, have broad development prospects. In the future, the proportion of functional composite materials will exceed the structure composite materials and become the mainstream of the development of composite materials.

Composite materials are divided into:

1. Metal and metal composite materials.

2. Non-metal and metal composite materials.

3. Non-metallic and non-metallic composite materials.
