“…The FF cross ply displayed greater mechanical integrity than the sized CF cross ply, which can be observed in Figure 1 The SEM and STEM images of the fuzzy fibres are displayed in Figure 2. The density of the growth was observed to be significantly greater than that reported in previous work [17] and is such that the CF (the growth substrate) is not visible apart from the regions where the catalyst has not been able to deposit (see Figure 2b). The lengths of the CNTs varied from 10 µm to 300 µm.…”

“…Thermal heating is provided via top-down from an array of light-sources (halogen tungsten bulbs, maximum output of 8 kW) which efficiently delivers thermal energy to the top of the fibres whilst the bulk of the fibres remain in contact with the cooled substrate holder [18]. This method of heating has demonstrated to deliver low degradation to CFs under CNT growth conditions [17]. Iron oxide was reduced by flowing hydrogen, at a flow of 200 sccm and pressure of 10 Torr, for a duration of 10 minutes at 750 o C.…”

“…The reinforcing carbon fibres (CFs) provide the high strength and elastic modulus necessary for critical components, whilst the polymer matrix (typically thermoset, but also thermoplastic) allows the load to be exerted evenly temperatures typically associated with CNT growth (typically 600 -1200 ºC) [16,17] result in thermal degradation to the CFs [16] and removes the polymer sizing. Subsequently, a low-temperature approach for growing the CNTs and metallic architecture on the carbon fibre that circumvents this limitation is used, showing an industrially-viable way of implementing this in large-scale.…”

Full terms of use are available: http://www.bristol.ac.uk/pure/about/ebr-terms AbstractHigh quality multi-walled carbon nanotubes (CNTs) grown at high density using a low temperature growth method are used as an alternative material to polymer sizing and is utilised in a series of epoxy composites reinforced with carbon fibres to provide improved physical and electrical properties. We report improvements for sizing-sensitive mechanical and physical properties, such as the interfacial adhesion, shear properties and handling of the fibres, whilst retaining resin-infusion capability. Following fibre volume fraction normalisation, the carbon nanotube-modified carbon fibre composite offers improvements of 146 % increase in Young's modulus; 20% increase in ultimate shear stress; 74 % increase in shear chord modulus and an 83 % improvement in the initial fracture toughness. The addition of CNTs imparts electrical functionalisation to the composite, enhancements in the surface direction are 400%, demonstrating a suitable route to sizing-free composites with enhanced mechanical and electrical functionality.

Carbon fiber reinforced carbon matrix (carbon/carbon, C/C) composites have become the promising candidates for high‐temperature thermal structure materials in aerospace fields, owning to a series of excellent structural merits. However, for aculeate or thin‐walled C/C composites, due to the fact that continuous carbon fibers are cut off during the machining process and the amount of residual carbon fibers is limited, carbon matrix cannot be effectively strengthened just by using carbon fibers, resulting in a sharp decline in mechanical performance. Furthermore, the rapid development of aerospace vehicles requires that C/C composites not only have excellent mechanical properties but also possess multifunctional properties. To effectively solve these problems and meet the increasing demands, various 1D nanostructures as nanoreinforcements have been introduced into C/C composites, achieving the great improvement in mechanical and functional properties. In this review, the state‐of‐the‐art research activities regarding different 1D nanoreinforcements applied in C/C composites are systematically summarized. Finally, this review is concluded and the future research prospects are proposed. This review provides the “1D nanoreinforcements” strategy to further improve the properties of C/C composites, which could be widely used for reference by researchers in the fields of different fiber/matrix composites.

The aim of this work is to enhance the electrical conductivity of PAEK/continuous carbon fiber (CF) composites while maintaining their mechanical properties. A conductive sizing was elaborated by mixing polyetherimide (PEI) with silver nanoplates (AgNpts) in suspension in dichloromethane. An aqueous PEI formulation was used as insulating sizing reference. The presence of AgNpts into the sizing enhances electrical conductivity up to 0.2 S.m −1 for a silver content 0.2 vol % without any modification of mechanical properties. The influence of conductive sizing on PAEK-AgNWs/CF was observed. For low AgNWs content lower (<1 vol %); the conductive sizing increases the electrical conductivity of the composite by one decade. This result shows that both types of Ag particles participate to the conductive path. For higher AgNWs content, electrical conductivity (200 S.m −1 ) is independent from the AgNpts content: the conductive path is only constituted by AgNWs. Mechanical properties of such composites show that the value of the conservative modulus is almost the same, while the dissipative modulus slightly increases. The global mechanical properties of the composite are preserved despite the addition of the CF, AgNWs, and AgNpts.
