Summary: This study investigated the tribological performance of hybrid composites composed of scrap carbon fiber (CF), glass fabric (GF), and polyamide 6.6 (PA6.6) through an innovative approach. The results demonstrated that the incorporation of CF and GF reinforcements had a detrimental effect on erosion resistance, while CFs positively affected scratch hardness. The silane treatment of GFs improved the erosion resistance and scratch hardness of GF/PA6.6 composite laminates without CF.

Summary: This study investigated the bond behavior of the carbon fabric-cementitious matrix interface within the fabric reinforced cementitious matrix composite through pullout tests. The effect of matrix impregnation on the bond behavior between the fabric and matrix was examined, revealing that impregnated filaments make up approximately 30% of the total filaments within an embedded carbon yarn. Different bond slip relationships for the impregnated and non-impregnated parts of the carbon yarn were evaluated and validated through experimental results and finite element modeling.

Summary: To improve the air permeability and durability of chemical protective clothing (CPC), researchers locked highly exposed activated carbon nanoparticles inside the chamber of porous meta-aramid fibers through physical blending and wet-spinning. By adjusting the pore parameters of the fibers, both the adsorption capability of the fibers to hazardous gases and the mechanical properties of the fibers were optimized. The resulting fiber demonstrated high adsorption capacity, sufficient tensile strength, and recyclability, while the developed fabric showed higher air permeability and a firmer loading of activated carbon compared to commercial CPC.

Summary: This study presents a simple method to prepare durable antibacterial cotton fabric without sacrificing wearing comfortability. The cotton fabric is oxidized to obtain dialdehyde groups and then treated with PM molecules to establish a PM coating on the fiber surfaces. The resulting fabrics show durably antibacterial activity with high bacterial reduction rates against E. coli and S. aureus, and they also exhibit remarkable durabilities after multiple washing cycles and rubbing times. The fabrics are proven to be safe for human skin through cytotoxicity tests. This research demonstrates a versatile strategy to impart effective and durable antibacterial function to cotton textiles, showing great potential for practical applications in functional textile fields.

Summary: This paper investigates the tool-ply friction behavior of jute/PLA biocomposites in thermoforming. 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.

Summary: Micro-arc oxidation (MAO) treatment was used to modify aluminum (Al) alloys in order to improve bond strength with carbon fiber reinforced polymer (CFRP). The treatment successfully created a porous surface with better hardness, roughness, and wetting, and introduced resin pre-coating (RPC) and carbon nanotube (CNT) fiber bridging to improve the bonding interface. The combined treatments significantly increased the bond strength by up to 156.1%, indicating the feasibility of MAO as an alternative method for manufacturing high-performance Al-CFRP composites in industrial production.
