Excellent performance of carbon fiber Carbon fiber is a fibrous carbon material with a carbon content of more than 90%. It is pre-oxidized, carbonized and graphitized with organic fibers such as PAN fiber, viscose fiber and asphalt fiber. It is prepared by a high-temperature solid-phase reaction process and consists of preferentially oriented graphite crystallites, thus having high strength and elastic modulus (rigidity). It has a specific gravity of 1.70 g/cm3 to 1.80 g/cm3, a strength of 1200 MPa to 7000 MPa, an elastic modulus of 200 GPa to 400 GPa, a thermal expansion coefficient close to zero, and even a negative value (~1.5×10-6).
 
Carbon fiber has a series of excellent properties such as high specific strength, high specific modulus, high temperature resistance, corrosion resistance, fatigue resistance, creep resistance, electrical conductivity, heat transfer and small coefficient of thermal expansion. These excellent comprehensive properties make carbon fiber the most important reinforcing fiber for advanced composite materials. It can be used to enhance polymer (thermosetting, thermoplastic polymer) to form high performance polymer matrix composites; enhance aluminum, magnesium, copper and other metal composition carbon / Aluminum, carbon/magnesium, carbon/copper and other metal matrix composites; reinforced carbon, ceramic composition, high temperature resistant ceramic matrix composites, carbon fiber composites can be designed to meet the performance of the matrix, fiber selection, carbon fiber content and distribution. A variety of high-performance components for a variety of requirements.
 
Glass fiber is an inorganic non-metallic material with excellent performance. It has many advantages, such as good insulation, heat resistance, good corrosion resistance and high mechanical strength, but the disadvantage is that it is brittle and wear resistance is poor. It is made of glass ball or waste glass by high-temperature melting, drawing, winding, weaving and other processes. The diameter of the monofilament is several micrometers to twenty meters micrometers, which is equivalent 1/20-1/5 to a hair strand, each bundle of fiber strands consists of hundreds or even thousands of monofilaments.
