Summary: The study systematically investigated the effect of seawater ageing on the mechanical properties of composites made with three types of unidirectional carbon fibers and a novel powder epoxy system. The results showed a significant strength reduction in composites due to seawater ageing, primarily influenced by differences in interfacial adhesion and moisture uptake. Additionally, Finite Element analysis and scanning electron microscopy revealed insights into important modeling parameters and the effects of seawater ageing on the materials.

Summary: The dual interface-enhanced sizing agents were prepared using self-assembled nano-polymers to achieve high surface roughness and interfacial wettability. Five self-assembled nano-polymer modified water-based sizing agents (NPSAs) with different cross-linking structures were synthesized. NPSAs exhibited homogeneous particle size in the range of 90-200 nm and heat stability below 200 degrees C. The CF surface properties were significantly improved by NPSAs, with surface roughness and surface energy reaching high values of 13.89 nm and 40.22 mN m-1. The CF/ER composites sized by NPSAs showed enhanced interlaminar shear strength (ILSS), flexural strength, and fracture toughness (KIC) by 70%, 51%, and 120% compared to the unoptimized composite, respectively. The reinforcing mechanism of NPSAs was clarified through the coefficient of thermal expansion (CTE1), which improved the interfacial interlocking and adhesion ability of CF/ER composites. Additionally, NPSAs have the advantages of simple one-pot synthesis methods and no use of toxic solvents.

Summary: This paper presents an experimental study on 3D printing of continuous carbon fibre reinforced thermoset epoxy composites. The study shows that the produced composites have high tensile strength and modulus in the fibre direction due to the good wettability of epoxy and high fibre volume fraction. The study also demonstrates the design freedom of the produced filaments for complex geometries and the improved strength of composites with designed stress-lines fibre paths.

Summary: A novel co-curing process using carbon fibre/PEEK tapes was proposed for bonding carbon fibre/epoxy composites, resulting in significantly improved structure integrity and thermal stability. The co-cured joints exhibited increased lap-shear strengths, extended fatigue life, and enhanced mode-I and mode-II fracture energies compared to joints bonded with traditional aerospace structural adhesives. The failure analysis revealed that plastic deformation, resin breakage, and carbon fibre delamination were the main failure mechanisms of the CF/PEEK bonded joints.

Summary: In this study, two types of carbon fibre (CF)-reinforced polydicyclopentadiene (PDCPD) composites were prepared using CF powder and cloth. The effects of CF content and curing temperature on PDCPD mechanical properties were investigated, and reinforcement mechanisms were explored microstructurally. CF cloth-reinforced PDCPD achieved a tensile strength of 405 MPa and bending strength of 213 MPa, higher than those of CF powder-reinforced PDCPD. Based on the results, PDCPD composites reinforced with CF powder can be used in automotive exterior trims, while PDCPD composites prepared using CF cloth can be used in load-bearing parts of automobiles.

Summary: Epoxy-based nanocomposite coatings with various fillers were developed to enhance mechanical and wear resistance properties. The addition of nanometer-sized TiO2 and SCFs improved the tensile properties, while the addition of graphite and ZnS had a negative effect. However, the interfacial shear strength between the coatings and steel was not significantly affected by the fillers. The coating filled with optimized filler combination (TTGCS5) showed significantly reduced wear rates compared to the epoxy sample, with ZnS showing a greater effect at 100°C. The optimal filler content was determined for achieving the best friction rates for the epoxy coating.

Summary: The study investigated the effect of hybrid carbon nanofillers on the electrical and flexural properties for an epoxy matrix and basalt fiber reinforcing composite subjected to seasonal water absorption. Results showed minimal changes in mechanical properties after environmental ageing. Nanomodified BFRCs exhibited slightly higher effects on flexural characteristics due to higher defectiveness. Nanocomposites showed higher electrical conductivity, with UD BFRC/NC showing significantly improved conductivity after hydrothermal ageing, enhancing damage monitoring capabilities.

A heat transfer model was developed to identify the relationship between processing parameters and heating of the carbon fibre tows. Results showed that Joule heating provides efficient heating with low power consumption. It was also found that slower speeds might yield more consistent quality, and it is possible to increase production rate without compromising quality by altering key process parameters.

Summary: The present study aimed to investigate the impact of crystallisation morphology and kinetics on the matrix-dominated properties of CF/PEKK composites, factors that have been minimally studied together in existing literature. Different processing routes, including compression-moulding and automated tape placement (ATP), were employed to examine their effects on void content, crystallinity development, morphology, and mechanical performance. Results showed that compression-moulded laminates achieved similar levels of consolidation and crystallinity under different isothermal crystallisation conditions, while the spherulitic development varied significantly. The performance of ATP laminates was lower due to higher void content and lower crystallinity, indicating the need for a comprehensive understanding of the correlation between processing conditions and crystalline structure development in PEKK.

A pull-through friction testing device was developed to characterize the tool-ply friction behavior of jute/PLA prepreg at elevated temperature. The effects of alkali treatment, fiber orientation, normal force, and slipping velocity were studied, and a quantitative definition of tool-ply friction behavior was achieved. The results indicate a strong relationship between tool-ply friction behavior and woven and fiber structures, indicating hydrodynamic lubrication.
