Composite materials in the performance of each other to complement each other, resulting in a synergistic effect, so that the comprehensive performance of the composite material is better than the original constituent materials.
The matrix materials of composites can be divided into two categories: metallic and non-metallic. Metal matrix commonly used aluminum, magnesium, copper, titanium and its alloys; non-metallic matrix mainly synthetic resins, rubber, ceramics, graphite, carbon and so on. Reinforcement materials include glass fibers, carbon fibers, boron fibers, aramid fibers, silicon carbide fibers, asbestos fibers, whiskers, metal wires, and hard fine particles.
Composites are used in a wide range of applications, including aerospace, automotive, construction, sports equipment, medical equipment, etc. Composites play an important role in these fields with their lightweight, high strength, high modulus, and unique features. With the development of technology, composite materials are also expanding new application areas.
