Summary: In this study, the tensile and flexural behavior of metal-nanocomposite laminates under different loading conditions were investigated. The effects of adding different weight percentages of MWCNTs on the mechanical properties of the laminates were evaluated. The results showed that the addition of up to 1 wt% of MWCNTs increased the tensile and flexural strengths, but further addition led to a decrease in strength due to aggregation and agglomeration of MWCNTs.

Summary: The incorporation of multi-walled carbon nanotubes (MWCNT) into phosphogypsum has been found to have multifaceted effects on its properties. The addition of MWCNT significantly shortens the setting time, enhances the strength and water resistance of phosphogypsum, and promotes its hydration process.

Summary: This study aimed to enhance the mechanical performance of glass fiber-reinforced polymer composites by incorporating multi-walled carbon nanotubes (MWCNT) and graphene nanoparticles (GNP) individually and in combination. Different weight fractions (0.1 to 0.3%) of these fillers were added to manufacture composite laminates with three different configurations. Characterization tests and failure analysis were performed, showing significant improvements in compressive strength, modulus, flexural strength, modulus, and interlaminar shear strength (ILSS). However, properties started to degrade beyond the optimal filler content of 0.2%, attributing to the agglomeration of MWCNTs/GNPs. The order of layups in terms of mechanical performance was UD, CP, and AP.

Summary: Non-monotonic electrical resistance changes have been observed in multi-walled carbon nanotube (MWNT)/epoxy nanocomposites under tensile loading, but the mechanism is not fully understood. This study evaluates the impact of curing condition on the piezoresistivity of MWNT/epoxy nanocomposites, and suggests that a higher curing temperature can enhance the monotony of the piezoresistivity. The results indicate that the molecular structure of the polymer matrix contributes to the non-monotonic piezoresistivity of CNT/epoxy nanocomposites.

Summary: This paper proposes a method to determine the optimum surfactant amount for carbon nanotubes cementitious composites. The results show that mixing with 0.08% surfactant-to-cement weight ratio achieves the highest flexural and compressive strengths, while exceeding this concentration reduces the strengths.

Summary: In this study, a comprehensive theoretical framework is proposed to investigate the tensile mechanics of complex random networks of multi-walled carbon nanotubes. By constructing a shell-based analytical model, the Young's modulus of multi-walled carbon nanotubes is successfully reduced and the tensile strength of Buckypaper is modeled. The good agreement between the theoretical model and experimental results validates the predictive capability of the model.

Summary: In this study, the effect of ply stacking sequence on the performance of carbon/epoxy laminates under flexural, tensile and impact loading was investigated. The results showed that unidirectional laminates exhibited higher flexural and tensile strength. Symmetric cross-ply laminates had improved flexural and tensile modulus compared to the unsymmetric counterpart. Quasi-isotropic laminates had higher impact resistance than other samples.

Summary: Short single-wall carbon nanotubes (SWCNTs)/epoxy composites with a low weight ratio of SWCNTs (0.03% to 0.5%) were fabricated. The tensile fracture strength initially increases with increasing SWCNT content, reaches a maximum at 0.05 wt%, and then decreases. A model analysis suggests that the transition from local matrix fracture to SWCNT debonding is responsible for the decrease in tensile strength. The study partly explains the variations in fracture strength observed in CNT reinforced composites.

Summary: This paper provides an overview of carbon fiber and its characteristics, application, and properties in carbon fiber-reinforced concrete (CFRC). The variation of selected mechanical properties of CFRC with different fiber dosages compared to conventional concrete, including compressive strength, flexural strength, and splitting tensile strength, is comprehensively analyzed. The limitations of existing literature and areas for future research and development are also discussed.

Summary: The study aimed to enhance the anti-corrosion performance of epoxy resin by incorporating f-MWCNT/PIn nanocomposite. The 0.25 wt% f-MWCNT/PIn blended nanocomposite coating showed excellent anti-corrosion and barrier protection properties in electrochemical testing. Uniform dispersion of nanofiller and increased pathway of corrosive electrolytes make it an excellent coating material for anti-corrosion applications.
