Carbon fiber is a fiber filament obtained by heating an organic material with carbon as the main component in an inert gas environment. Carbon fiber fabric contains at least 90% of carbon, which is obtained by specially controlling fiber pyrolysis. Carbon fiber has high corrosion resistance, such as acidity, openings and materials. Carbon fiber reinforced polymer (CFRP) is usually made of two carbon wrapping materials (carbon fiber cloth or carbon fiber fabric). The first is a one-way carbon package, the carbon fiber is parallel to the zero degree direction, and the second is a two-way carbon package, the carbon fiber is in two directions, zero and perpendicular to it (90 degrees). Carbon packaging is used in many fields, such as building renovation, defense industry, automobile industry and many other important industries. Carbon fiber coating materials usually use materials such as epoxy resin and FRP thixotropic epoxy adhesive to improve the load-bearing capacity of the structure and improve the shear, bending and bending resistance of the components.

Carbon fiber fabric

The mechanical properties of carbon fiber fabrics such as light weight and high resistance make it widely used in the composite material industry and structural seismic reinforcement. One of the most important advantages of carbon fiber fabrics is their light weight and high tensile strength.

Carbon fiber is one of the most widely used fibers in the composite material industry. This fiber has the greatest tensile strength among other types of fibers (glass fiber and aramid fiber). The linear expansion coefficient of carbon fiber is low at both high and low temperatures, resulting in the dimensional stability of the carbon fiber coating at different temperatures. Among the various advantages of carbon fiber (and subsequent carbon packaging), the most prominent ones are tensile strength and light weight (carbon is about one-third the weight of steel, and 5 to 10 times the weight of steel). In addition, carbon fiber has good fatigue resistance. Carbon fiber's durability, chemical resistance, long life and X-ray opacity are one of the most outstanding properties of carbon fiber. In addition, carbon fiber fabric has excellent electrical conductivity, fabric texture and manufacturing capabilities, the manufacture of lightweight composite materials and solid carbon fiber reinforced plastics, and its heat resistance, which distinguish it from other engineering materials. The price of carbon fiber is due to its long life and provides high durability. Over time, the cost-effectiveness and economic aspects have become more and more significant.
