“…Due to a related patenting process, the sketch of the continuous EPD prototype cannot be shown in the current paper. In this prototype, the distance between the anode (carbon fiber (CF) fabric) and cathode (two aluminum plates positioned opposite to both surfaces of the fabric) is fixed as 10 mm so as to generate an electric field with the strength of 10 V/cm at a direct current (DC) power supply of 10 V. The strength of the electric field was decided by several factors: (1) the resistance of the deposit is almost independent of the electric field from 10 V/cm and above, especially for the suspension with a concentration lower than 0.05 wt% [13]; lower electric fields lead to higher resistance and a lower deposit yield, (2) higher power leads to increasing energy consumption and promotes the electrolysis of water theoretically occurring at a potential of 1.23 V, which will generate bubbles that behave as insulation between CFs and CNT suspension, resulting in vacancies on the fabric without CNT deposit. In order to reduce the impact of water electrolysis and improve the dispersion of CNTs as well as postpone the aggregation of CNTs (the phenomena and reasons are described in the following sections), ultrasonication together with a circulation system was applied during the entire EPD process.…”

“…Santhanagopalan et al reported the continuous deposition of CNTs on long strips of metal foil; a pump with a flow rate of eight mL/min was used to replenish the CNT dispersion [10]. Three research groups, led by Jiang [11,12], Li [13], and Huang [14], respectively, reported the coating of graphene oxide on carbon fibers and fiber tows continuously via EPD. The discontinuous EPD process is also very likely to increase the CNT discards, which will increase the production cost of CNT-deposited fiber reinforcement using this technique due to the high cost of CNT materials.…”

An electrophoretic deposition (EPD) prototype was developed aiming at the continuous production of carbon nanotube (CNT) deposited carbon fiber fabric. Such multi-scale reinforcement was used to manufacture carbon fiber-reinforced polymer (CFRP) composites. The overall objective was to improve the mechanical performance and functionalities of CFRP composites. In the current study, the design concept and practical limit of the continuous EPD prototype, as well as the flexural strength and interlaminar shear strength, were the focus. Initial mechanical tests showed that the flexural stiffness and strength of composites with the developed reinforcement were significantly reduced with respect to the composites with pristine reinforcement. However, optical microscopy study revealed that geometrical imperfections, such as waviness and misalignment, had been introduced into the reinforcement fibers and/or bundles when being pulled through the EPD bath, collected on a roll, and dried. These defects are likely to partly or completely shadow any enhancement of the mechanical properties due to the CNT deposit. In order to eliminate the effect of the discovered defects, the pristine reinforcement was subjected to the same EPD treatment, but without the addition of CNT in the EPD bath. When compared with such water-treated reinforcement, the CNT-deposited reinforcement clearly showed a positive effect on the flexural properties and interlaminar shear strength of the composites. It was also discovered that CNTs agglomerate with time under the electric field due to the change of ionic density, which is possibly due to the electrolysis of water (for carboxylated CNT aqueous suspension without surfactant) or the deposition of ionic surfactant along with CNT deposition (for non-functionalized CNT aqueous suspension with surfactant). Currently, this sets time limits for the continuous deposition.

“…For example, Jiang et al employed GO as the sizing agent for carbon fiber ( CF ) using the electrophoretic deposition (EPD) method. The EPD process can increase the surface roughness and oxygen content of SCF when compared with the raw CF , thereby improving the CF /epoxy matrix interfacial shear strength.…”

“…Fibers reinforced polymer composite materials (FRPCM) are well acknowledged for lightweighting due to their outstanding mechanical properties and high strength to weight ratio. However, FRPCM need to overcome certain drawbacks related to poor transverse mechanical properties and an interfacial interaction problem leading to an ineffective stress transfer and easy crack initiation and propagation . The solution for such limitations passes upon the development of new fillers that can preserve the composite interfacial properties.…”

This work presents an analytical approach for solving the nonlinear mechanical response of hybrid glass fibers reinforced graphene polymer composite materials. Two‐scale homogenization technique derives the effective properties of the composite. At the first scale, the properties of a 2‐phases graphene/polymer composite are obtained by accounting for the J2 plasticity coupled with the “Lemaitre–Chaboche” ductile damage model. An interfacial imperfection between the fillers and the matrix is considered through the linear spring model (LSM). At the second scale, the modeling of the 3‐phases glass fibers/graphene/polymer composite combines the 2‐phases composite as a matrix phase in which are embedded the glass fibers. For both scales, a modified Mori–Tanaka scheme derives the effective properties. Numerical results, obtained for a thermoplastic PA6 matrix, are compared with the multistep method of Digimat software. Finally, a tension–torsion test shows that the imperfection at the fibers/polymer interface is the driven parameter to weaken mechanical responses in the shear direction.
