Microwave plasma carbonization for the fabrication of polyacrylonitrile-based carbon fiber

A microwave plasma system is designed for low cost next-generation carbon fiber (CF) process. The microwave plasma-carbonized carbon fiber had mechanical properties as good as the conventionally carbonized one. Furthermore it had increased level of surface roughness, which enhance the mechanical interlocking between CF and resin that high strength CF reinforced polymer can be made using it.
