Many people do not realize that the \n carbon fiber product they are purchasing is not entirely carbon fiber. True \n carbon fiber is made in a pre-preg and dry process which consists of vacuum \n forming sheets of carbon fiber into a mold at temperatures around 350° F, \n sometimes referred to as an autoclave. This process allows carbon fiber to form \n into a strong and lightweight composite. Like most race car parts. On the other \n hand, wet carbon fiber is formed by using hand laid carbon fiber sheets into \n a mold then mixed with resin. This process generally allows air pockets to form \n in the carbon fiber material. This makes the wet carbon fiber structure weak \n and also is susceptible to changes in temperature. \n \n You can usually notice the difference between wet carbon fiber and dry carbon \n fiber by looking at the surface of the material. Dry carbon fiber surfaces are \n smooth and show no air bubbles. In contrast, wet carbon fiber is wavy and air \n bubbles are noticeable. Because of the molding process, dry carbon cost more \n to produce then wet carbon, however, since wet carbon fiber looses its durability \n over time, dry carbon is the best product for the long term. \n\n
