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.

Enhancement of mechanical and thermal properties of carbon fiber epoxy composite laminates reinforced with carbon nanotubes interlayer using electrospray deposition

Carbon nanotubes (CNTs) was successfully deposited onto the surface of woven carbon fiber (CF) using the electrospray deposition method to produce a woven hybrid CF-CNT. The effect of voltage and spray times on the morphology of the woven hybrid CF-CNT have been studied. The voltage and spray time is crucial towards achieving a homogeneous CNT coating on the woven CF surface. The epoxy composite laminated with optimized woven hybrid CF-CNT and woven CF without the deposited CNTs were then prepared, and its tensile and thermal properties subsequently determined. The results showed that the woven hybrid CF-CNT epoxy composite laminates tensile strength increased by ~21%, its tensile modulus increased by ~37%, its interlaminar shear strength increased by ~25%, and its thermal conductivity increased by ~35% relative to that of the woven CF epoxy composite laminates.
