“…For all that, the ultimate strain values of E-MWCNT-1 and E-MWCNT-1.5 obtained in this study were relatively high, compared to other studies [35,36]. According to the studies of Rahmanian et al [37] and Martone et al [38], such differences in mechanical behaviors of epoxy-MWCNTs nanocomposite test specimens were due to the dispersion morphology of the carbon nanotubes. When a higher amount of MWCNTs was added and dispersed into the epoxy, it could enhance the tensile stress transferring across the cracks and thus lead to increase of the strength of test specimens.…”

Multiwalled carbon nanotubes (MWCNTs) and nanoscaled electroless copper plating were introduced to enhance the mechanical properties of carbon fiber reinforced polymer (CFRP) composites in this study. e influence of multiwalled carbon nanotubes (MWCNTs) with weight fractions of 0.5-1.5% of epoxy resin on the mechanical properties of CFRP composites was investigated.e MWCNTs and epoxy resin was first mixed, prior to impregnating the carbon fiber fabrics. Electroless copper plating, a deposit method using simultaneous reactions in an aqueous (copper) solution without external electric power, was applied on the carbon fiber surface, and the effect was also investigated. e CFRP test specimens were fabricated by hand lay-up method, using one or three carbon fiber fabrics. e mechanical properties of the CFRP test specimens were derived by tensile tests according to KS M ISO 527-4. According to the morphology taken by SEM, the carbon fiber surface was significantly rough with copper ions. Because of this, the strength and ultimate strain of coated specimens increased up to 26.3 and 18.6% compared to noncoated specimens, respectively. In addition, as the MWCNTs amount increased, the ultimate strain of the composites also increased. In the case of CFRP test specimens using noncoated carbon fiber fabrics, the addition of 1.5% wt. MWCNTs increased the peak strength and ultimate strain of CFRP specimens up to 80.5 and 48.8%, respectively. Finally, the tensile stress-strain relationship of CFRP specimens was idealized as bilinear or trilinear response curves.

“…10,11 The weak mechanical properties associated with the photopolymer cause the prototype to fracture and lose useable value. 12 During the last few years, an overwhelming amount of researches have been carried out to understand and improve both the process and the photopolymer. 13,14 All of these have been carried out with an aim of achieving prototypes with higher strengths.…”

As an additive manufacturing technology, ultraviolet (UV)-curing three-dimensional printing, which requires the use of a photocurable resin, is increasingly being used to produce customized end-user parts of many complex shapes. In this study, to improve the strength and ductility of printing materials, nano-SiO 2 -reinforced photocurable resins were prepared by a planetary ball mill; then, the morphology, photochemistry, thermal property, and mechanical properties of the nanocomposites were investigated and characterized. Transmission electron microscopy analysis indicated that the modified nano-SiO 2 was well dispersed in the photocurable resin. The glass-transition temperature increased from 67.28C for the unfilled resin to 71.7 and 80.18C for nanocomposites with nano-SiO 2 contents of 0.3 and 0.7 wt %, respectively. The tensile strength and impact strength were increased by 46.7 and 165.3% for nanocomposites with 0.3 wt % nano-SiO 2 . The flexural modulus of the nanocomposites increased from 1.7 to 8.0 GPa when 0.7 wt % nano-SiO 2 was added to the photocurable resin; this appeared to originate from the relatively high level of dispersion and the intimate combination of the nano-SiO 2 with the matrix. The investigation of the physical and chemical properties of such UV-curing materials showed that the low filler concentration (<1 wt %) of nano-SiO 2 did not affect the processability of the nanocomposites.

“…As the name suggests, "multiscale" composites comprise reinforcements at varying scales, such as continuous or discontinuous fibers of the order of mm, along with microscale fibers and/or nanoscale fillers or tubes. They are manufactured by merging nanoscale-sized fillers (e.g., CNTs) with traditional fiber reinforcements like glass and carbon [150,151]. The fiber resists in-plane load whereas the nanoscale reinforcement improves the performance of the through-thickness direction.…”

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.
