“…The graphite crystallites on the CF skin layer are in a compact arrangement and lack active carbon atoms. This results in low surface energy and inadequate functional groups for chemical reactions [44]. Based on experimental evaluations on a CF-epoxy system [45,46], the IFSS is influenced chiefly by the local morphology of the outermost graphite surface layers and the number of active sites.…”

The fibre-matrix interface represents a vital element in the development and characterisation of fibre-reinforced polymers (FRPs). Extensive ranges of interfacial properties exist for different composite systems, measured with various interface characterisation techniques. However, the discrepancies in interfacial properties of similar fibre-matrix systems have not been fully addressed or explained. In this review, first, the interface-forming mechanisms of FRPs are established. Following a discourse on three primary factors that affect the fibre-matrix interface, the four main interface characterisation methods (single-fibre fragmentation, single-fibre pull-out, microbond and fibre push-in/-out tests) are described and critically reviewed. These sections review various detailed data reduction schemes, numerical approaches, accompanying challenges and sources of reported scatter. Finally, following the assessment of several infrequent test methods, comprehensive conclusions, prospective directions and intriguing extensions to the field are provided.

“…36 The interface area is capable to transfer stress, heat or electrons between fiber and matrix. 37 The presence of a weak interface under specific stresses results in fiber/polymeric debonding or sliding. With transferring the stress ineffectively, the stronger interfaces are obliged to endure greater stresses.…”

Fiber reinforced polymer composites (FRPCs) have gained great progress in a wide range of applications from construction and building structures to automobile and vehicle systems. During the operational lifetime, some FRPCs are exposed to various environmental conditions such as thermal cycles and thermal shocks. Fluctuation of the ambient temperature in the forms of thermal shocks or thermal cycles is one of the most important factors that deteriorate the durability and performance of the FRPCs. Compared to ceramic composites, less attention has been paid to the effects of thermal shocks and thermal cycles on the physical/mechanical properties of FRPCs. A comprehensive insight for the future advancements in this field is essential to possibly reduce the failure risks of FRPCs under thermal shocks and thermal cycles. The present work provides a comprehensive review on the physical/mechanical behavior of FRPCs under thermal cycles and thermal shocks. This work also provides a broad review on several factors that determines mechanical behavior of FRPCs, such as polymeric matrix, fiber type, incorporated nanofillers and fiber/polymer interface. Recent studies denoting important aspects and possible problems in mechanical performance of FRPCs under thermal shocks are also summarized.

“…3,4 However, the mechanically weakest link in CFRPs is generally the junction between the fiber and the epoxy due to weak bonding between them because of the chemically inert surface of CF. 5 The interface/interphase is a transition region where fiber and epoxy can potentially form chemical bonds and mechanical interlocking. Therefore, CFRPs' properties majorly depend on the interface/interphase strength of the transition region in which load transfer occurs from the epoxy to CF when subjected to mechanical loads.…”

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.
