Summary: This study investigates the effect of carbon nanotubes (CNTs) on the strength behavior of cementitious tailings backfill (CTB). The results show that CNTs significantly improve the strength and microstructure of CTB by inhibiting crack expansion and enhancing material integrity. Among them, ordinary multi-walled CNT (CNTPL) has the most significant impact on the mechanical properties of CTB. In conclusion, this study demonstrates that using the fractal properties of microstructure can better estimate the strength development of CTB specimens reinforced with different types of CNTs.

Summary: Fiber-reinforced polymer composites, especially carbon fiber-reinforced epoxy (CFRE) laminates, have been widely used in the aircraft and aerospace industry. The interface between the matrix and fiber plays a critical role in determining the overall structural properties of CFRE laminates. In this study, electrophoretic deposition (EPD) was used to deposit covalently coupled multiscale graphene oxide (GO)/carbon nanotube (CNT) nanoconstructs onto carbon fiber (CF) fabric, resulting in improved flexural strength and interlaminar shear strength compared to the neat CFRE. The deposition of GO/CNT nanoconstructs improved the performance of CFREs by enhancing wettability, surface free energy, and surface roughness.

Summary: Carbon nanotube (CNT) has been increasingly used in concrete due to its good mechanical properties and electrical conductivity. This paper provides a comprehensive review on the use of CNT in concrete, including its effects on workability, mechanical properties, durability, and microscopic mechanisms. The results show that CNTs can bridge cracks, fill pores, and enhance the performance of concrete, while also reducing workability. Different dispersion modes and functionalizations of CNTs are discussed, as well as their applications as conductive fillers and self-sensing concrete. Overall, CNTC is a promising building material with various applications.

Summary: This study investigates the effects of an eco-friendly ultrasonic-assisted resin infiltration process on the carbon nanotube (CNT) film and its based composites. It is found that ultrasonication can reduce CNT bundle diameter and increase film stretchability, resulting in improved performance of CNT film-based composites. However, excessive sonication can damage the crystal structures of CNTs and degrade the mechanical properties.

Summary: Shear and thermal processing can affect the orientation and dispersion of nanoparticles, thus influencing the conductive and mechanical properties of nanocomposites. The synergistic effects of shear flow and Carbon nanotubes (CNTs) nucleating ability on the crystallization mechanisms have been proven. Different molding methods were used to produce Polylactic acid/Carbon nanotubes (PLA/CNTs) nanocomposites, and annealing was applied to study the effects on electrical conductivity and mechanical properties. The volume exclusion effect significantly impacts the oriented CNTs, resulting in a significant increase in transverse conductivity.

Summary: The introduction of in-pipe robots for sewage cleaning provides new options for pipe inspection, such as leakage, crack, gas, and corrosion detection. However, the resistance of the robots to corrosion is often overlooked. This study discusses the effects of incorporating different weight percentages of carbon nanotubes (CNTs) into aluminum 7075 on its mechanical, microstructural, and corrosion properties. The 1wt% CNTs-aluminum nanocomposite shows good corrosion and mechanical properties, meeting the requirements for sewage environment.

Summary: In this study, carbon fiber composite laminates were modified by carbon nanotube films. Out-of-plane compressive properties were improved by CNT interlaminar toughening, but the dynamic in-plane compression performance was decreased due to delamination inside of CNT film. Two methods were used to prepare the mode I fracture test and results showed that CNT prolonged crack propagation path and improved interlaminar fracture properties.
