“…Hence, scholars are committed to researching graphene oxide or reduced graphene oxide based carbon fiber reinforced composites [16]. A hierarchical composite containing carbon fibers and graphene nanosheets in epoxy resin matrix was successfully prepared, coating graphene nanoplatelets on carbon fibers via an electrophoretic deposition process [17] Compared with the reference composites, the interlaminar shear strength of the composite has increased by about 24 %. The reason may be that in the presence of graphene nanosheets, homogeneous stress distribution, and chemical integration between the fiber and resin have emerged.…”

Carbon fiber reinforced composites have attracted lots of attention in many fields. However, on account of the poor infiltration of resin to carbon fiber, the weak interface performance between fiber and resin has been restricting the interface properties of composites. In recent progress, the review attaches more importance to the introduction of the third phase monomer, which mainly uses physical and chemical methods to assemble nanomaterials (such as carbon nanotubes, graphene, etc.) on the carbon fiber surface to modify the interface structure of the carbon fiber reinforced composites, and all of them have been demonstrated in this paper. Furthermore, the effects of introducing nanomaterials on the structure of the fiber/resin interface and the relationship between multi‐scale interface structure and properties have been investigated. It can be seen that the design idea of researchers mainly uses one or more theories to improve the interface properties of carbon fiber reinforced composites, such as transition layer, chemical bonding, mechanical interlocking, infiltration, diffusion, and adsorption. In brief, this work provides some novel insights for the preparation of carbon fiber reinforced composites with excellent interlaminar shear strength.

“…As a result of these factors, ultimate tensile strength property of material is improved. 30,31 Consequently, it can be concluded that the GnPs have an improving effect on the tensile strength property not only by being oriented along the tensile axis, but also by locating at the interface between the matrix and the fiber, mediating more load transfer and enabling the fibers to carry more load.…”

Although petroleum-based polymers require a long process to decompose in nature, they still have a wide range of uses. However, due to many important reasons such as the environmental pollution problem caused by these polymers, there is an increasing interest in biodegradable polymers. Poly(lactic acid) (PLA) is a biopolymer with comparable performance to conventional polymers. However, due to its poor tribological, mechanical and thermal properties, the usage area of PLA cannot expand and its use is limited to short-term material applications. In this study, it was aimed to contribute to the expansion of the usage area of PLA by improving its poor properties. For this purpose, efficiency of graphene nanoplatelet (GnP) and/or Joncryl® addition to carbon fiber (CF) reinforced PLA matrix composites to improve the composite performance by means of improved interface interaction fiber and matrix was investigated. Within this scope, effects the separately and/or simultaneously addition of CF, GnP and Joncryl® to PLA on properties were investigated by tensile test, adhesive wear test, DSC, TGA and SEM analyses. All results revealed that the composite composition prepared by simultaneously addition of 10, 0.5 and 2 wt.% CF, GnP and Joncryl®, respectively, to pure PLA performed the best in all tests and analyses.

Carbon fiber-reinforced polymer composites (CFRPs) show high specific strength and stiffness compared with other fiber-reinforced polymer composites. However, these composites are most likely to fail at the interface/interphase of fiber and epoxy owing to minimal interaction between the epoxy and the fiber due to the chemically inert nature of the carbon fiber (CF) surface. Many CF surface modification techniques have been reported to increase the interfacial strength. Moreover, in some cases, incorporation of graphene fillers on the CF surface is an effective way to enhance the interfacial adhesion strength between CF and epoxy. Electrophoretic deposition is an effective technique to deposit graphene nanofillers on the CF fabric. In the current study, a novel combination of carboxyl-functionalized graphene (G-COOH) and magnesium nitrate hexahydrate (Mg(NO 3 ) 2 •6H 2 O) has been chosen for preparing colloidal solution to deposit G-COOH on carbon fibers. This colloidal solution facilitates the adsorption of more Mg 2+ ions on the large number of active carboxyl functional groups present at the edges of G-COOH platelets and develops a positive charge on them. These platelets get deposited on the cathodic electrode (i.e., carbon fiber fabric) with higher electrophoretic mobility during EPD. Hence, a uniform film-type layer of G-COOH platelets has been deposited with reduced EPD process parameters such as weight concentration of G-COOH platelets in suspension solution (g/L), deposition time, and voltage compared to other studies. The surface morphology of G-COOH platelet deposition on carbon fiber fabric has been examined using scanning electron microscopy (SEM). Surface characteristics of CFs have been studied using energy-dispersive X-ray spectroscopy (EDS) area mapping, FTIR, and Raman spectroscopy. Four layers of pristine and G-COOH platelet-deposited carbon fiber fabrics have been used to manufacture the final composites through the vacuum-assisted resin transfer molding (VARTM) technique. An increase in interphase thickness of the G-COOH CF composite over the pristine carbon fiber (PCF) composite was observed through carbon elemental EDS line scanning. The G-COOH-deposited CF composite showed enhancement in tensile strength and strain but reduction in flexural properties compared to PCF composites. This is due to the higher prevalence of void formation in the G-COOH-deposited composite.
