Herein, the effects of multi-walled carbon nanotubes (CNTs) on the mechanical and dielectric performance of hybrid carbon nanotube-woven glass fiber (GF) reinforced epoxy laminated composited are investigated. CNTs are deposited on woven GF surface using an electrospray deposition method which is rarely reported in the past. The woven GF deposited with CNT and without deposited with CNT are used to produce epoxy laminated composites using a vacuum assisted resin transfer moulding. The tensile, flexural, dielectric constant and dielectric loss properties of the epoxy laminated composites were then characterized. The results confirm that the mechanical and dielectric properties of the woven glass fiber reinforced epoxy laminated composited increases with the addition of CNTs. Field emission scanning electron microscope is used to examine the post damage analysis for all tested specimens. Based on this finding, it can be prominently identified some new and significant information of interest to researchers and industrialists working on GF based products

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

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.
