The effects of surface treatment of high strength carbon fibers on the impact properties of 2D and 3D carbon fiber reinforced composites and carbon/carbon composites are studied. It is found that air oxidation of carbon fibers deteriorates the impact property of the composites because of declined fiber/matrix interfacial strength due to creation of micro-pore on the carbon fiber surface. The impact property of heat treated (HT700 and HT950) carbon composites is superior to that of any other treated composites because of increased effective surface area of carbon fibers. The 3D structure is suitable for carbon/carbon composite in toughening aspect.
