“…Interleaving, the insertion of an additional layer between dry fibre reinforcements or prepreg layers, is a common way of improving both the interlaminar fracture toughness and the conductivity of CFRPs. Work has been carried out that considers both the through-thickness conductivity and the interlaminar fracture toughness, with some work succeeding in maintaining or improving the interlaminar fracture toughness whilst also improving the conductivity [4,9,73]. The work of Guo and Yi [36] gives a novel approach, with the use of AgNW coated paper interleaves as a means of conductivity improvement.…”

As the use of carbon fibre reinforced polymers (CFRP) is continuing to increase in engineering applications, more functionalities will be required. Having an enhanced through-thickness electrical conductivity can be a useful functionality for CFRPs which will minimise their damage from lightning strikes, and will help in their real-time monitoring. For most modification methods there is an adverse effect on the manufacturing and the fibre volume fraction, which influence the mechanical properties of the resulting composites. Simultaneous improvement of multiple properties of CFRPs is difficult, and as such the ways in which different materials and processes improve properties of CFRPs need to be understood in depth. This review discusses research that attempts to improve the through-thickness electrical conductivity of CFRPs with interest in the effects on mechanical properties, specifically interlaminar fracture toughness. The last section discusses the effect and use of these methods to improve structural health monitoring (SHM) of CFRP.

“…Silver-plated PPTA fibers have excellent antibacterial, anti-radiation, anti-static and electromagnetic shielding properties, which greatly broadens the application of PPTA fibers, such as thermal sensing materials for smart clothing, electronic communication protection materials and multi-functional aerospace materials [3,4]. Electroless silver plating is the most widely used method to produce silver nanoparticle coated fibers [5][6][7]. However, as the surface reactivity of PPTA fibers is extremely low due to the displacement resistance of a large number of benzene ring formation and the conjugate effect of benzene rings and amide groups, it is difficult to obtain silver nanoparticle coated PPTA fibers by direct electroless plating.…”

Direct electroless silver plating of para-aramid (PPTA) is difficult due to its extremely low surface chemical energy. In order to facilitate the deposition of silver nanoparticles and to enhance the washing fastness, oxygen plasma treatment and dopamine modification were conducted before silver plating of PPTA fibers. Various techniques including scanning electron microscopy (SEM), attenuated total reflection Fourier transform infrared spectroscopy (ATR-FTIR), X-ray diffractometer (XRD) and thermogravimetric analyzer (TGA) were used to characterize the surface morphology, chemical composition and thermal stability of the silver-plated PPTA fibers. Electrical resistance and silver content of the silver-coated PPTA fibers before and after standard washing were also studied. The results showed that silver nanoparticles were successfully coated onto the surface of PPTA fibers with and without plasma treatment, but the coating continuity and the electrical conductivity of the silver-coated PPTA fibers were greatly enhanced with the assistance of plasma treatment. It was also demonstrated that the washing fastness of silver-coated PPTA fibers was improved after plasma treatment as indicated by electrical resistance and continuity of the silver nanoparticles after various washing cycles. It was found that the electrical resistance of plasma-treated PPTA-PDA/Ag fibers prepared at an AgNO3 concentration of 20 g/L reached 0.89 Ω/cm and increased slightly to 0.94 Ω/cm after 10 standard washing cycles. The silver-coated PPTA fibers also showed stable electrical conductivity under 250 repeated stretching-releasing cycles at a strain of 3%.
