Preparation of bicomponent fibers by surface modification with fibrous carbon nanostructure filler

Surface treatment of carbon PAN fibers was performed by growing carbon nanostructures using chemical vapor deposition and a mixture of benzene and cyclohexane at 800°C. Fibrous samples with deposited catalyst and with the initial surface were characterized by scanning electron microscopy, Raman scattering, and x-ray phase analysis. Furthermore, the micromechanical characteristics of a model composite monofilament—epoxide matrix were studied using fiber fragmentation. It was found that the resistance to interphase shear for a composite reinforced by surface-treated fiber increased 2.3 times compared with untreated fiber.
