“…The primary role of carbon nanotubes was to improve the contact between single carbon fibres [10]. An additional beneficial effect of MWCNT incorporation may be the dispersive strengthening of the matrix, which is a common phenomenon widely described in the literature [28,29]. The well-dispersed MWCNT filling the gaps between fibres can be observed in Fig.…”

The aim of this study was to investigate potential applications of milled secondary carbon fibres as a primary filler in conductive polymer composites. The examined composites were based on epoxy resin, milled secondary carbon fibres and selected carbon nanoadditive used as a secondary conductive filler.Three kinds of nanopowders were tested: multiwalled carbon nanotubes, graphene nanoplatelets and graphitized carbon black. In the first stage of the experiment, composites with different percentages of carbon fibres were examined in order to determine the electrical conductivity and percolation threshold. Subsequently, the most conductive composition (70% of carbon fibres, r = 9.05 S cm -1 ) was modified by adding nanofillers. The addition of carbon nanotubes caused more than twofold increase in in-plane conductivity to 20.18 S cm -1 . The composites with graphene nanoplatelets showed deterioration of properties due to strongly increased viscosity of a binder with graphene. Small loadings of graphitized carbon black had a minor positive impact on the electrical conductivity and mechanical properties of composites.

“…Experimentalists have attempted to enhance GFRP properties by using various nanofillers, with significant contribution made by using carbon nanotubes (CNTs) [22][23][24][25][26][27][28][29][30] which consists of graphene layers rolled up in the form of cylindrical tubes that possess excellent properties, such as high strength and stiffness, higher electrical and thermal conductivity, huge aspect ratio, and barrier properties [29][30][31][32].…”

Glass fiber-reinforced polymer composites (GFRP) were prepared and reinforced with two types of multiwalled carbon nanotubes, i.e., amino-functionalized (ACNT) and pristine nanotubes (PCNT). Incorporation of ACNT leads to a significant decrease in equilibrium water content and diffusion coefficient vis-à-vis GFRP composites when immersed in seawater (SW) and distilled water (DW). The experimental results illustrate that the material degradation of the composites is significantly more on immersion in SW as compared to DW. Interestingly, a decrease in mechanical properties was observed initially; however, at a later stage the trend reversed and a recovery in the mechanical properties was seen. This recovery in mechanical properties is ascribed to the possible secondary crosslinking network between excess sodium ions in seawater with the hydroxyl groups of cured epoxy and also to the unreacted silanols on the glass fiber surface. On the contrary, PCNT composites revealed a continuous decreasing trend in mechanical behavior versus aging duration. The present study suggests that it may be advantageous and safer to re-condition (for 15-20 days) FRP nanocomposite parts before being installed in naval vessels.

“…Further improvement in mechanical properties has been reported after the addition of amino functionalized CNT in PNC. 1,[3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] Besides, effective interfacial bonding between the composites individual constituents the properties of the composite materials is primarily dependent on the dispersion of CNT in the polymer matrix. Thus, at present the full potential of CNTs as reinforcement is still limited due to the non-homogenous dispersion of CNT as they exist as agglomerates and also due to poor interfacial interaction between CNTs and the polymer matrix.…”

In the present study, 2-ply glass fiber epoxy composites were prepared with aminofunctionalized carbon nanotubes using Vacuum assisted resin infusion molding (VARIM) technique. The focus is to evaluate the different processing techniques used to uniformly disperse nanotubes in resin and their effect on mechanical properties. In addition, the dispersion and mechanical performance by incorporating aminonanotubes in curing agent vis-à-vis epoxy resin is also studied. Lastly, the mechanical behavior of composites on increasing the resin infusion temperature prior to its fabrication is also investigated. The mechanical results along with SEM and TEM images validate the proposed processing methodology and use of higher infusion temperature.
