Carbon fiber is a kind of very high carbon content material, by other fiber under high temperature carbonization and graphitization, softness of graphite and the characteristics of the diamond is hard.Its use range is very wide, now has been used in the space shuttle, sporting goods, model planes, high-speed rail, car modification, medical apparatus and instruments, using range and in the further.Carbon fiber varieties, the quality of the products on the market is uneven, how to distinguish the stand or fall of the carbon fiber material?

All of the carbon fiber products are made from carbon fiber strand.A strand quality pass, should be homogeneous structure without defects.From above, the interception, and compared the whole fiber generally no two, various properties such as strength, too.Carbon fiber strand is very thin, only about one over twenty of a human hair, a bunch of carbon fiber is composed of innumerable root strand, inside each strand strength, size is very uniform, that is a good carbon fiber material.
 
If you want to produce good quality carbon fiber, needs, from the perspective of the production technology and raw materials.Raw materials, used in the manufacture of carbon fiber polyacrylonitrile, asphalt, such as cellulose to pure, too many impurities will be passed on to the carbon fiber, add some of the catalyst also cannot use inferior materials.Production process, strictly control the temperature of the polymerization time and flow rate, stirring speed and pressure, these parameters should be according to the actual situation and decide, constantly testing optimization.
