英文摘要: Abstract(#br)Nanostructured uniform pyrolytic carbon (PyC) coatings with different thicknesses were prepared on surface of T700 carbon fiber by chemical vapor deposition (CVD). The effect of coating on tensile strengths of the carbon fibers was studied by tow tensile strength test. The morphological change, roughness, microstructures, and thermal stability of carbon fibers with PyC coating (PyC-C f ) were investigated by SEM, AFM, XRD, Raman, and Tg. It was found that with increase of the deposition time, the thickness of coating varied from 100 to 320 nm with increase in coating surface roughness. The coating adhered well with the carbon fiber substrates and the coating thickness is uniform. The oxidation resistance of PyC-C f was significantly higher than uncoated carbon fibers....
