“…[5][6][7][8] To do so, fillers are usually incorporated/dispersed into the polymer matrix aiming to assist the conduction process either by being dispersed in the bulk of the laminate [6,[9][10][11] or by nanostructuring the interlaminar regions. [5,12] The objective of all of these approaches is to interconnect the adjacent laminae through a percolating network of conducting fillers. However, parameters such as the state of agglomeration, the geometry, and aspect ratio of the filler as well as the viscosity of the matrix, to name some, influence the particle network structure.…”

The influence of out‐of‐plane alignment of graphene oxide (GO) platelets used as matrix filler on the through‐thickness electrical and thermal conductivity of unidirectional carbon fiber‐reinforced polymers (CFRPs) composites has been investigated. By utilizing an external AC field, the orientation of GO flakes was altered to take advantage of the higher electrical and thermal conductivity along the graphene basal planes. Commercially available GO was dispersed in quantities up to 5 wt% into the epoxy matrix prior to vacuum infusion into dry carbon fabric to form CFRP laminates. Both GO‐modified CFRP laminates containing randomly oriented GO and aligned GO‐modified CFRP (A‐GO/CFRP) laminates were manufactured to assess the influence of the application of the electric field. Measurements of the electrical conductivity revealed markedly increased values for the A‐GO/CFRP even with low filler contents. The thermal conductivity, albeit increased in A‐GO/CFRP, only resulted in modest improvements. Mechanical tests of the interlaminar shear strength (ILSS) showed that the A‐GO/CFRP laminates exhibited significantly improved behavior and retained higher ILSS values (than the randomly aligned GO/CFRP laminates) even at high filler contents.

“…Different methods for improving the conductive performance have been proposed, which show promising results including the incorporation of nano-fillers in the bulk matrix [7][8][9], grafting on the surface of the carbon fibres by adding nano-inclusions into the sizing [5,6,10], growing nano-inclusions directly on the carbon fibre surface through a chemical vapour deposition (CVD) process [4], electrophoretical deposition of the filler on fabrics [11], and nano-structuring in the interlaminar region [1,12]. Although there are differences in the methods listed above, they all share a common characteristic: the use of a conducting filler as a means to enhance the electrical and thermal conductivity of the polymer matrix or the properties of the sizing on carbon fibres [10].…”

Enhancement of the electrical and thermal properties of unidirectional carbon fibre/epoxy laminates through the addition of graphene oxide

A means of enhancing electrical and thermal conductivities of carbon fibre reinforced polymer (CFRP) composites is investigated for the purpose of reducing damage when electric current and/or heat is introduced into a CFRP structure. The addition of commercially available graphene oxide (GO) nanoflakes dispersed into an epoxy resin is studied; quantities up to 6.3 vol% are used in a vacuum infusion process with carbon fibre fabric to form CFRP laminates. Measurements of the anisotropic electrical and thermal conductivity of the laminate were conducted on CFRP specimens with and without the GO nano-flakes. It is shown that the electrical conductivity in the through-thickness direction increased markedly, reaching values up to 0.18 S/cm, when 6.3 vol% of GO was added into the epoxy, showing a threefold increase compared to the neat CFRP. Similar improvement was also found in the thermal throughthickness conductivity for the same filler content, where the laminate exhibited identical values in both transverse and through-thickness directions. However, the properties transverse to the fibres were not greatly affected by the GO addition. To assess the effect of the GO on the mechanical properties, interlaminar shear strength tests were conducted that showed that the addition of the GO significantly enhanced the through-thickness shear strength.

“…[4][5][6] This phenomenon can greatly affect the overall mechanical properties of laminates, such as compressive properties, flexural performance, interlaminar shear strength (ILSS), and so on. [7][8][9] Good interfacial adhesion can effectively transfer stress from the matrix to the reinforcement, which conduce to dispersion of stress and an increase mechanical strength on the composites. [10][11][12] To reinforce the interface of CFRP, CF surface need to be modified.…”

Catechol‐based co‐deposited carbon fiber surfaces for enhancement of fiber/epoxy composites

et al. 2020

To improve interfacial adhesion between carbon fiber (CF) and epoxy resin, a low‐cost and environment‐friendly method was developed to treat the CF surface via the bio‐inspired co‐deposition of catechol (Cc) and polyethyleneimine (PEI). It is noteworthy that the deposition process reacts at room temperature with water as solvent, and does not require harsh conditions or the use of toxic reagents. After treatment, the CF/epoxy composites were endowed with excellent mechanical properties and showed increases of 51.9% and 51.7% for flexural strength and ILSS, respectively, in comparison with unsized CF laminates. The analyses of fractured surface morphologies and strengthening mechanism of the composites indicated that the uniformly coated Cc‐PEI on the fiber surface can promote the diffusion and entanglement of the matrix molecular chains and form chemical bonding as well as π‐π stacking, thus effectively improving the interfacial adhesion. In addition, the facile process disclosed in this study can provide a new strategy to not only for CF treating but also expected to be used in the modification of other high performance fiber reinforcement and industrial applications.
