Abstract

Carbon nanofibres (CNF)/silicon carbide (SiC) composites have been fabricated by electrospinning of cellulose acetate and SiC nanoparticles, followed by deacetylation and carbonization. Carbon nanotubes (CNTs) were then grown on the surface of the CNF/SiC composite nanofibres via a chemical vapor deposition (CVD) method. Raman spectroscopy was used to characterize the crystallinity of CNF/SiC and CNF/SiC/CNTs samples by comparing the Raman D and G band intensity ratio (ID/IG), and the full width at half maximum (FWHM) of bands. Elastic modulus of the CNF/SiC/CNTs fibres was estimated using a Raman spectroscopic method by observing the shift of the 2D Raman band during tensile deformation of the fibre composites; a value of 166 ± 28 GPa was estimated, which is comparable to medium stiffness commercial carbon fibre filaments. The unique structure of these composite nanofibres combined with their high modulus could make them useful as reinforcements for composite materials.
