SURFACE TREATMENT AND INTERFACE EFFECT OF CARBON FIBERS

In the present study we used gaseous oxidative procedure which carried out, with simple equipment,easy operation and likable with manufacturing line of carbon fibres.By using gaseous oxidation of carbon fibres an inter-laminar shear, strength (ILSS) of the carbon fibre reinforced plastic(CFRP) Can be increased by 36-56%.This is attributed to the increased concentration of chemical fuactional groups on the fibre surface.It was found that tensile serength of carbon fibre can be increased by 11-31% because of the removal of surface flaws.
