Abstract The morphology and microstructure of the worn surface of carbon-carbon (C/C) composites, which were fabricated by CVD process and finally heat treated after 2300℃, were studied using scanning electron microscopy and transmission electron microscope. Most pyrolytic carbon around the fiber is high-textured pyrolytic, and there is a 1 μm thick low-textured pyrolytic intergrade layer between the fiber and the high-textured pyrolytic. The wear tests were simulating the normal landing of aircraft braking. The results showed that a compacted low-textured pyrolytic carbon friction film which is about 1 μm thick covered the worn surface after the wear tests.
