    The electrospray deposition method was used to deposit carbon nanotubes (CNT) onto the surfaces of woven carbon fiber (CF) to produce woven hybrid carbon fiber-carbon nanotubes (CF-CNT). Extreme high-resolution field emission scanning electron microscopy (XHR-FESEM), X-ray diffraction (XRD), Raman spectroscopy and Fourier transform infrared spectroscopy (FT-IR) were used to analyze the woven hybrid CF-CNT. The results demonstrated that CNT was successfully and homogenously distributed on the woven CF surface. Woven hybrid CF-CNT epoxy composite laminates were then prepared and compared with woven CF epoxy composite laminates in terms of their flexural and dielectric properties. The results indicated that the flexural strength, flexural modulus and dielectric constant of the woven hybrid CF-CNT epoxy composite laminates were improved up to 19, 27 and 25%, respectively, compared with the woven CF epoxy composite laminates.

    In this study, the electrospray deposition (esD) method was used to deposit carbon nanotubes (cNT) onto the surfaces of carbon fibers (cF) in order to produce hybrid carbon fiber-carbon nanotubes (cF-cNT) which is rarely reported in the past. extreme high-resolution field emission scanning electron microscopy (XHR-FeseM), high-resolution transmission electron microscopy (HRTeM) and x-ray photoelectron spectroscopy (XPs) were used to analyse the hybrid carbon fiber-carbon nanotube (cF-cNT). The results demonstrated that cNT was successfully and homogenously distributed on the cF surface. Hybrid cF-cNT was then prepared and compared with cF without cNT deposition in terms of their tensile properties. statistically, the tensile strength and the tensile modulus of the hybrid cF-cNT were increased by up to 3% and 25%, respectively, as compared to the cF without cNT deposition. The results indicated that the esD method did not cause any reduction of tensile properties of hybrid cF-cNT. based on this finding, it can be prominently identified some new and significant information of interest to researchers and industrialists working on cF based products.
