“…Simultaneously, efficient doping took place due to electron transfer between the nitrogen-induced atoms from the amine group of the PEI molecules on the CNTs, resulting in both stable and efficient n-type films. 46,47 The p-type SWCNT positive Seebeck coefficient of the films is caused due to doping by oxygen in air leading to hole carriers. 48,49 Since the primary goal of this study was to produce waterbased inks for industrial-scale and facile printing applications, acidic treatment methods were not preferred for p-doping enhancement as referred to in previous studies.…”

“…This includes low strength, low toughness, high brittleness, low thermal and electrical conductivities, etc. The insulating properties of the polymer matrix and low transverse conductivities of carbon fibres present a barrier to various useful applications including resistive or induction heating for more efficient processing [1], [2], sensing and current collection applications [3], lightning strike protection [4] [5], EMI shielding [6], [7], etc. This problem is exacerbated for other common composite reinforcements, such as glass, Kevlar, or natural fibre, which lack electrical conductivity even in the fibre direction.…”

Conventional carbon fibre laminates are known to be moderately electrically conductive in-plane, but have a poor through-thickness conductivity. This poses a problem for functionality aspects that are of increasing importance to industry, such as sensing, current collection, inductive/resistive heating, electromagnetic interference (EMI) shielding, etc. This restriction is of course more pronounced for non-conductive composite reinforcements such as glass, organic or natural fibres. Among various solutions to boost through-thickness electrical conductivity, tufting with hybrid micro-braided metal-carbon fibre yarns is one of the most promising. As a well-characterised method of through thickness reinforcement, tufting is easily implementable in a manufacturing environment. The hybridisation of materials in the braid promotes the resilience and integrity of yarns, while integrating metal wires opens up a wide range of multifunctional applications. Many configurations can be produced by varying braid patterns and the constituting yarns/wires. A predictive design tool is therefore necessary to select the right material configuration for the desired functional and structural performance. This paper suggests a fast and robust method for generating finite-element models of the braids, validates the prediction of micro-architecture and electrical conductivity, and demonstrates successful manufacturing of composites enhanced with braided tufts.

A mathematical model of the stress state of a three-layer metal composite system caused by cutting forces during grinding the working layer of the system is elaborated. The implementation of the model by using the finite-element method made it possible to assess the effect of structure of the system, the deformation properties of layer materials, and grinding conditions on the distribution and level of normal and tangential stresses in layers, which determine the load-carrying capacity of the system. The results of an analysis of stress fields can serve as a basis for determining the grinding conditions ensuring retention of the load-carrying capacity of the metal composite system.
