    Abstract:

    The effects of interlaminal properties of composite with resin and carbon fiber woven modified with
    carbon nanutubes grown on carbon fiber are investigated. The interlaminal shear strength and flexural strength of car ̄
    bon ̄epoxy composite with four kinds of carbon nanutubes grown and without carbon nanutubes are compared. The
    effects of interlaminal properties of canbon nanotubes on carbon ̄epoxy composite with the method of the canbon nano ̄
    tubes film combinated with carbon fiber are also studied. It is showed that the interlaminal properties of carbon ̄epoxy
    composite with four kinds of carbon nanutubes grown is worse than that without carbon nanutubes because the inner
    defects increase for overlong canbon nanotubes and the resin can not immerse in the carbon nanutubes because canbon
    nanotubes are overlong( >10 μm) and form “cage” due to arranging disorderly on the end leading to carbon nano ̄
    tubes playing no reinforcing effect. The canbon nanotubes filmꎬhowever well combined with carbon fiber and resinꎬ
    leading to the interlaminal shear properties improving 12%.
