According to different standards and requirements, composite materials usually have the following classification methods. (l) It can be divided into junction composite and functional composite according to different service properties. (2) The connector matrix materials can be divided into tree month, speech matrix composites, metal matrix composites, and inorganic non-metallic matrix composites. (3) According to the morphology of dispersed phase, it can be divided into continuous lower dimensional reinforced composites, fiber fabrics, braided reinforced composites, sheet reinforced composites, short fibers or whiskers reinforced composites, and particle reinforced composites. (4) It can be divided into carbon fiber composite, glass fiber composite, organic fiber composite and ceramic fiber composite according to the type of reinforcement fiber.
