Surface Treatment of Carbon Fiber for Composites

The carbon fiber and its composites have many excellent performances,such as the high specific strength,the high specific modulus,the heat endurance,anti-corrosion,anti-fatigue,anti-creep etc.It is very important to treat the surface of carbon fibre for making use of its performances.This thesis summarizes several approaches of surface treatment of carbon fibre,for example,gas oxidation,electrolysis oxidation,liquid oxidation, plasma oxidation,electro-polymerization,vapor deposition,electroplating,and compares the influences of different surface treatment methods on the fiber's structure and properties.The surface treatment of carbon fiber is an important measure that makes use of its performances.The surface treatment of carbon fiber is different for making use of requirement.By comparing several treatment approaches,it can be concluded that: ozone oxidation,anode electrolysis oxidation and plasma oxidation are widely used now.
