“…26° that confirms graphitic planes in their structure [24,25]. Two main peaks are observed for all 12 nanocomposites at about 2$ = 20.5°±0.1 and 2$ = 23.9°±0.1where correspond to (200), (002) and (220) [26,27] or (100), (010) and (110) [28] reflections which are characteristic of the !-crystalline form. These peaks depict induced !-form crystalline microstructure by PCNTs and CCNTs in the nanocomposites.…”

“…This prevents the nanotubes from agglomerating and helps in achieving stabilization and good dispersion of CNT within the base matrix. This engagement between the particles and the resin system improves the final properties of the CNTs/polymer composites [156][157][158][159][160][161][162][163][164][165]. The carboxyl (-COOH) or hydroxyl (-OH) groups present on the CNTs' surface provide a conducive environment for the various chemical reactions to take place [166][167][168].…”

Abstract:Composite materials are prone to delamination as they are weaker in the thickness direction. Carbon nanotubes (CNTs) are introduced as a multiscale reinforcement into the fiber reinforced polymer composites to suppress the delamination phenomenon. This review paper presents the detailed progress made by the scientific and research community to-date in improving the Mode I and Mode II interlaminar fracture toughness (ILFT) by various methodologies including the effect of multiscale reinforcement. Methods of measuring the Mode I and Mode II fracture toughness of the composites along with the solutions to improve them are presented. The use of different methodologies and approaches along with their performance in enhancing the fracture toughness of the composites is summarized. The current state of polymer-fiber-nanotube composites and their future perspective are also deliberated.

“…There was an increase of 8.2% in breaking strength while there was an increase of 56.4% in breaking elongation with the addition 3w% amino-functionalized carbon nanotubes. In order to achieve significant improvements in the mechanical properties of the polymer composites with carbon nanotubes, the main challenge is to obtain a good dispersion of carbon nanotubes [15,16]. The small increase in breaking strength accompanied by a high increase in breaking elongation was most likely due to the agglomeration of carbon nanotubes and void formation around the agglomerates.…”

In this study, DMSO was used as the solvent and PAN nanofibers reinforced with amino-functionalized multiwalled carbon nanotubes (f-MWCNTs) were successfully electrospun from the electrospinning solutions prepared in DMSO. The concentrations of f-MWCNTs were changed as 1w% and 3w% with respect to the weight of PAN. The effect of f-MWCNT concentration on morphology, conductivity and mechanical properties of composite nanofibers were examined and compared to that of pure PAN nanofibers. Uniform composite nanofibers were obtained. The diameters of the nanofibers were in the range of 515-536 nm. The addition of the f-MWCNTs resulted in an increase in nanofiber diameter. 3w% f-MWCNT loaded PAN/f-MWCNT nanofiber showed the best mechanical properties. Conductivity increased with the incorporation of amino-functionalized multiwalled carbon nanotubes.
