“…5a yielded the best fitting to the experimental data of the S0 and S1 composites for the whole period of immersion. Alias and Brown [55] used the same model to simulate the EIS response of carbon fibereepoxy and carbon fiberevinyl ester composites. In this model R 1 is the electrolyte resistance; Q 1 and R 2 are related to the composite/electrolyte interface where R 2 is the pore resistance to the penetration of electrolyte and Q 1 models the associated capacitance.…”

h i g h l i g h t s < Development of ABSegraphiteeMWNT composite bipolar plates. < EIS successfully applies for understanding the corrosion mechanism of the composites. < MWNT concentration strongly affects the corrosion behavior of the ABSegraphite composites. < The best balance of properties was for the ABS-graphite composite with addition of 2 wt.% MWNT. a b s t r a c tComposite bipolar plates based on the proper mixing of multi-walled carbon nanotubes (MWNTs), synthetic graphite particles and acrylonitrileebutadieneestyrene (ABS) powder have been produced by hot compression molding. The corrosion properties of the molded plates were assessed through electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization curves. Through-plane and in-plane electrical conductivities were determined. The relevance of electrochemical oxidation to the electrical conductivity of the composites was assessed by cyclic voltammetry. Thermal stability of the composites was examined by thermogravimetric analysis (TGA). The morphology of fractured surfaces of the plates was observed by scanning electron microscopy. The incorporation of MWNTs increased the inplane and through-plane electrical conductivity of the ABSegraphite composites. There was, though, a corresponding reduction of the corrosion resistance. The thermal behavior was little affected by the addition of MWNTs.

“…Not primarily the formed hydroxide ions but the reaction intermediates during the oxygen reduction such as peroxide and superoxide radicals are likely to cause the delamination. [15,28] 3.3 | Effects of cathodic polarization on the transverse tensile stress of CFRP Mechanical tensile tests were carried out to examine the effects of a cathodic polarization on the transverse tensile stress of carbon fiber reinforced plastic. Figure 10 compares the maximum transverse tensile stresses of the CFRP specimens of the conditions "dry," "wet," and "polarized."…”

This study investigates the corrosion behavior of the contact element CFRP‐aluminum under standardized corrosion conditions. Both, the corrosion of the aluminum alloy and the coupled corrosion of the carbon fiber reinforced plastic (CFRP) were examined. FE‐SEM analysis was performed to analyze the microscopic corrosive attack. While anodic corrosion was observed for the alloy especially close to the material transition, the cathodic corrosion of the CFRP led to fracture and buckling of the glass fibers and moreover to delamination between the carbon fibers and the epoxy matrix. Finally, the influence of a cathodic polarization on the transverse tensile stress resistance of the composite was tested. The observed carbon fiber/epoxy matrix debonding processes led to a significant reduction of the mechanical properties.

“…Whenever better properties in materials are necessary and extra costs can be accepted, then, carbon fibres are used to replace glass ones and autoclaves appear in processes [4]. But, unfortunately, neither glass, nor carbon fibres offer the ecosustainable option that meets the modern customers' expectations and desires.…”
