Graphene nanoplatelets (GNPs) are novel nanofillers possessing attractive characteristics, including robust compatibility with most polymers, high absolute strength, and cost effectiveness. In this study, GNPs were used to reinforce epoxy composite and epoxy/carbon fiber composite laminates to enhance their mechanical properties. The mechanical properties of GNPs/epoxy nanocomposite, such as ultimate tensile strength and flexure properties, were investigated. The fatigue life of epoxy/carbon fiber composite laminate with GPs-added 0.25 wt% was increased over that of neat laminates at all levels of cyclic stress. Consequently, significant improvement in the mechanical properties of ultimate tensile strength, flexure, and fatigue life was attained for these epoxy resin composites and carbon fiber-reinforced epoxy composite laminates.

In this paper, the influence of interlaminal contaminations of water, oil and paper on the mechanical properties of carbon fiber reinforced epoxy composite laminates was researched. The results showed that the existence of interlaminal layered contaminations greatly degraded the mechanical properties of composite laminates. The deterioration of mechanical properties resulted from oil contamination was most serious. It was concluded that the ultimate tensile strength (UTS), compression strength and ILSS were more seriously influenced than corresponding modules. How those contaminations affected the mechanical properties was discussed. For further understanding of the effecting mechanism of water contamination on the curing kinetics, the DSC curves of prepregs contaminated by water were compared with that of normal prepregs. It was found that the initial curing temperature of specimens with water contaminant was lower than that of control prepregs.

The effects of voids on the tensile and compressive properties of CFRP laminates were discussed in this paper. The tensile and compressive strength of specimens decreased with the porosity increasing from 0.33% to 1.50%. The empirical models of the tensile strength and the compressive strength of CFRP laminates with different porosities are established by using ORIGIN software. The evolution laws of the tensile strength and the compressive strength with different porosities were corresponding to the form of exponential function.

AbstractThe 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.
