Summary: Replacing artificial fibers with natural fibers to fabricate fiber-reinforced resin matrix composites is a research hotspot at present. How to improve the poor compatibility between plant fiber and resin matrix is hot spots in this area. Our work aims to modify RFF reinforced epoxy resin (RFF/EP) composite laminates with silicon polymer (PSOL) and improve the performance of the composite laminates.

Summary: The research focuses on the effect of plasma treatment on the surface of carbon nanotubes and aerospace grade epoxy resin composites. It was found that plasma treatment improves the dispersion of carbon nanotubes in the resin and enhances the resistance of the epoxy resin to crack propagation.

Summary: In this study, unzipped carbon nanotubes (uCNTs) and drilled carbon nanotubes (dCNTs) were prepared and anchored with Eu3+ complexes to form stable tenon structures. The results showed that Eu-dCNTs significantly improved the mechanical properties of EP, with a 161% increase in ultimate tensile strength and a 226% increase in flexural strength. The drilling treatment and tenon structure of Eu-dCNTs played a key role in enhancing the mechanical properties of EP.

Summary: This study introduced a novel approach to fabricate hybrid polymer nanocomposite coatings, demonstrating that the addition of an appropriate amount of nanoparticles can improve the coating's performance in terms of hardness and wear resistance. However, excessive nanoparticles negatively impact the samples' pull off strength, hardness, and modulus of elasticity.

Summary: The study found that GFRP reinforced with CNTs/epoxy film had better interlaminar fracture toughness in modes I and II compared to GFRP without film and embedded with Toner/epoxy film, and the interlaminar shear strength was significantly enhanced. The impact of low-temperature cycle on the interlaminar performance of GFRP reinforced with CNTs/epoxy film was not significant, and minimal compared to other specimens.

Summary: A z-directional nanoreinforcement approach was implemented to improve the mechanical performance of laminated composites under extreme temperature conditions. The composites with aligned functionalized carbon nanotubes (A-FCNT) consistently outperformed other composites in terms of flexural and interlaminar shear strength at all considered temperatures. The improved viscoelastic properties of the A-FCNT composite were attributed to the synergetic impact of functionalization and alignment.

Summary: The study investigated the thermal, mechanical, and water uptake properties of epoxy nanocomposites with surfactant-modified MWCNTs, showing that the addition of surfactant-modified CNTs into the epoxy significantly improved mechanical and thermal properties. However, excessive concentration of CNTs led to agglomeration and decreased the performance of the nanocomposites.

Summary: This study evaluated the mechanical, physical, thermal, and chemical properties of two commercially available adhesives (Epo-Tek 301 and Nano-Force E100) and prepared DGEBA adhesives with different percentages of HNTs and CNTs. The results showed that there were no significant differences in the properties between the neat DGEBA and DGEBA with 1 wt% HNTs. However, the properties deteriorated for adhesives with more than 1 wt% HNTs, and there was no enhancement in all properties for adhesives containing CNTs. The adhesives containing CNTs also exhibited higher viscosity, which could hinder resin infiltration for composite repair applications.

Summary: The correlationship between the molecular weight of surface-grafted polyglycidyl methacrylate (PGMA) and the dispersion state of PGMA-grafted MWCNTs was systematically investigated in this study. The molecular weight of surface-grafted PGMA was measured using X-ray photoelectron spectroscope (XPS) and thermos-gravimetric analyzer (TGA). The results showed that the dispersion state of MWCNTs-PGMA in PMMA solution was enhanced with the increase in the molecular weight of grafted PGMA. The EP composites exhibited the highest enhancement in mechanical properties when using MWCNTs-PGMA-3 with the largest PGMA molecular weight as the reinforcement.

Summary: The key to superior structural properties in polymer nanocomposites lies in the improved dispersion and enhanced interfacial adhesion of the reinforcement. By grafting epoxy chains directly onto graphene oxide, the mechanical properties of epoxy composites were significantly enhanced with just a small amount of graphene oxide.

Summary: This study investigates the influence of chemically grafting CNTs on the surface of carbon fibers on the mechanical properties of Ti/CFRP laminates. It was found that the grafting of CNTs significantly improved the bending and interlaminar shear strength of the laminates, as well as the deformation resistance and reduced damaged area.

Summary: The study focuses on enhancing the mechanical properties of Fiber-metal laminates (FMLs) by adding multi-walled carbon nanotubes (MWCNTs) to a polymer matrix, leading to a significant improvement in interface performance. The van der Waals energy, total energy, and interfacial interaction energy all showed varying trends with different diameters of MWCNTs, eventually stabilizing and indicating an improvement in interface properties. At an average MWCNT diameter of 8 nm, the interface fracture energy increased by nearly 180% compared to the material without MWCNTs.

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: By studying the concentration of modified BN solution, it was found that when 6g/L modified BN solution was added, the flexural strength, flexural modulus, ILSS, and G(IIC) of the composite increased by 12.7%, 10.4%, 37.0%, and 62.3%, respectively. And at -60 degrees C, these properties approached 894.6MPa, 34.6GPa, 60.4MPa, and 483.9Jm(-2), which were 20.0%, 10.7%, 38.9%, and 68.9% higher than that of EP-BF, indicating that EP-BF/mBN even had better mechanical performances at low temperature.
