Carbon fiber is a fibrous carbon material with a carbon content of more than 90%. It is using all kinds there
Organic fibers are made by carbonization in an inert gas at high temperature. Carbon fiber has very excellent mechanical properties, which is the highest specific strength and highest among the high-performance fibers that have been mass-produced.
The specific modulus of the fiber. Especially in the high temperature inert environment above 2000 "C, carbon material is the only material that does not decrease in strength. It is unmatched by other major structural materials, metals and their alloys. In addition to excellent mechanical properties, carbon fiber also has other A variety of excellent properties, such as low density, התנגדות לטמפרטורה גבוהה, עמידות בפני קורוזיה, התנגדות לחיכוך, fatigue resistance, high vibration attenuation, high electrical and thermal conductivity, low thermal expansion coefficient, high light penetration, non-magnetic but electromagnetic shielding, וכו. .
Second, the use of carbon fiber
As a kind of high-performance fiber, carbon fiber has both the inherent characteristics of carbon materials and the softness and processing of textile fibers. It is the most important reinforcing material for advanced composite materials. It has been widely used in various fields of military and civilian industries. From aerospace, aviation, automotive, מכשירי חשמל, machinery, chemical, textile and other civilian industries to sports equipment and leisure goods. Therefore, carbon fiber is regarded as a typical representative of new industrial materials in the high-tech field and attracts worldwide attention. The carbon fiber industry plays a very important role in the upgrading of pillar industries in developed countries and the improvement of the overall quality of the national economy. It also has important significance for the adjustment of China's industrial structure and the upgrading of traditional materials, and it has a significant impact on the defense industry and the national economy.
