Because of its high performance fiber corrosion resistance, high temperature resistance, superior mechanical abrasion and other physical and chemical properties, described as "Yifaqianjun", widely used in aerospace, military and other fields, civilian scale is also growing, which the most typical is carbon fiber. Currently, 95 percent of global carbon fiber market has been dominated by large foreign companies.

Carbon fiber reinforced material is advanced composite materials, with lightweight, high strength, high modulus, chemical resistance, low coefficient of thermal expansion and a series of advantages, summarized as follows:

(A) light weight, high strength, high modulus
The density of the carbon fiber is 1.6 ~ 2.15g / cm3, carbon fiber tensile strength 2.2GPa or more, and modulus than 230GPa. Thus, a high specific strength and specific modulus, it is higher than the strength of most metals than 7 times or more, or more than five times the modulus of the metal. Because of this advantage, and its composite materials can be widely used in aerospace, automotive, sports equipment and so on.

(B) the thermal expansion coefficient
The majority of the thermal expansion coefficient of the carbon fiber itself, the room temperature is negative (-0.5 ~ -1.6) × 10-6 / K, zero at 200 ~ 400 ℃, 1000 ℃ is at less than 1.5 × 10-6 / K. Expansion coefficient of the composite material is made ​​by its stable nature, the appliance can be used as a standard value.

(C) thermal conductivity
Inorganic and organic materials typically thermal resistance are poor, but close to the thermal conductivity of the carbon steel fibers. Take advantage of this material can be used as solar collectors, heat evenly thermal shell material.

(D)  good chemical resistance
As can be seen from the composition of the carbon fiber, it is almost pure carbon, and the carbon is one of the most stable elements. It is, except for strong oxidizing acids, a variety of acids, alkalis and organic chemicals are very stable and can be made of a variety of chemical preservative products. China has begun to engage in applied research in this area, as prices continue to reduce future carbon fiber, it will become increasingly wide range of applications.

(E) good wear resistance
When carbon fiber and metal-to-wear, with little loss, use is made of carbon fiber to replace asbestos advanced friction materials, has been used as aircraft and automobile brake pads materials.

(F) high temperature performance
Carbon fiber below 400 ℃ performance is very stable, even at 1000 ℃ still no big change. High temperature performance composite materials depends mainly on heat-resistant resin matrix composite substrate its long-term heat resistance of only about 300 ℃; temperature performance ceramic matrix composites, carbon-based and metal-based carbon fibers can match itself. Therefore, as the high temperature carbon fiber composite materials have been widely used in the aerospace industry.

(G) outstanding and excellent damping through sonar
Use these two kinds of characteristics can be used as a submarine construction materials, such as submarine sonar dome and so on.

(H) high x-ray transmittance
This feature has been applied to play in medical devices.

(I) high fatigue strength
Structural stability of carbon fiber composite materials, stress fatigue after millions of cycles test, the strength retention rate is still 60%, while 40% of steel, aluminum was 30%, while only 20 percent fiberglass ~ 25%. Therefore safety factor taken products, carbon fiber composite materials for the lowest.

China has been able to produce the equivalent of Japan's T300 carbon fiber carbon fiber tensile strength of 3632Mpa, tensile modulus 226.5GPa, elongation at break (%) 1.58, viscose fiber carbon fiber and pitch-based carbon fiber is in the research stage, compared to the species, size and number of foreign advanced level, the gap is large.
