The limited folding resistance of continuous silicon carbide (SiC) fibres hinders their application as flexible, foldable materials. With this objective in mind, the folding endurance and damage properties of the second (2nd) and third (3rd) generation continuous SiC fibre tows were investigated through repeated folding tests, optical microscope observation and tensile tests. These SiC fibre tows were disassembled from two-dimensional (2D) SiC fibre braided fabrics with varying braiding angles. The braiding process can alleviate the force on fibre tows during the textile forming process. The investigation of damage mechanisms and analysis of force conditions are instrumental in optimizing structural parameters. The research findings suggested that, in comparison to the 3rd generation continuous SiC fibres, the 2nd generation SiC fibre tows demonstrated higher resistance to repeated folding. In contrast, the 2nd generation fabrics exhibited slightly lower folding endurance values. After repeated folding, the SiC fibre tows in fabrics showed the highest strength losses near the braiding angle of 37.8° to 38.3°. In comparison, the SiC fibre fabric demonstrated the lowest folding endurance values (approximately 760 times) near the braiding angle of 41° to 42°. Considering factors such as folding endurance value, the strength loss rate of fibre tows and fabric strength loss rate, it can be concluded that SiC fibres in fabrics with large braiding angles exhibit optimal performance in terms of folding endurance.

Characterized by rapid maturation, short growth cycles, and high strength and toughness, bamboo can be compounded with polymers to produce bamboofiber reinforced polymeric composites (BFRPCs). These composites exhibit corrosion resistance comparable to traditional materials such as glass fiber and carbon fiber composites. Additionally, they possess features like low density, high strength, degradability, and environmental friendliness, with low production costs and strong industrial applicability. This paper reviews the accomplishments in BFRPCs and provides an overview of the production processes for BFRPCs. Furthermore, it summarizes the research status of mechanical properties, moisture absorption characteristics, interface performance, and flame retardancy of these composites. The current issues with BFRPCs were analyzed. Finally, the paper explores future research directions and potential applications of BFRPCs. Highlights: The performance studies on BFRPCs are comprehensively presented.Composite processing of BFPRCs is reviewed.Pros and cons of various types of BFRPCs are analyzed.Overview of the applications of BFRPCs in various domains is presented.Future trends and challenges of BFRPCs are introduced.

The combination of one-dimensional carbon nanotubes and two-dimensional transition metal carbon/nitride (MXene), using the electrochemical deposition method and the hydrothermal method to deposit manganese dioxide (MnO2) on the surface of the composite fiber. The results indicated that the fiber supercapacitor deposited by electrochemical deposition has a higher volumetric specific capacitance than the fiber supercapacitor deposited by hydrothermal method. The specific capacitance at a current density of 1 A/cm³ is about 97.5 F/cm³. After 2 500 cycles of charging and discharging, its final capacitance retention rate is about 74.5% of the original.

This study investigates the mechanical properties of Polyurethane Bark Gum (PBG) reinforced with Solid Glass Beads (SGBs) of varying diameters and content. The tensile analysis demonstrates that a 1% SGB volume fraction maximizes tensile stress and fracture elongation due to synergic composite effects, with smaller SGBs enhancing interfacial adhesion and reducing microcrack formation. The impact analysis revealed that the addition of SGB reduced the impact strength due to interface delamination and energy dissipation mechanisms, with optimal impact resistance observed at a particle size of 0.4–0.6 mm and a content of 5%. Morphological characterization was conducted using optical microscopy, scanning electron microscopy, and synchrotron radiation CT scanning techniques, highlighting the role of SGB in toughening, crack bridging, and stress shielding. This study provides insights into the performance of PBG/SGB composite materials and guides the material design for specific applications. [ABSTRACT FROM AUTHOR]
