Summary: In this study, the friction coefficient of AFRP composites was determined under various conditions, with high friction forces negatively affecting wear and leading to more prominent wear traces. Oxidation, fatigue (thermal), and delamination wear were found to be effective, as an increase in load resulted in higher forces on the samples.

Summary: This study compared the use of carbon matrix composite (CMC) wear-resistant plate and common wear-resistant (CWR) plate in replacing silica in rubber formula. The results showed that CMC wear-resistant plate exhibited a high friction coefficient and low wear rate in the mixing process of silica compound, while the opposite trend was observed for carbon black compound. The experimental results suggested that CMC wear-resistant plate is more suitable for a silica mixing process, and its increasing friction coefficient with decreasing wear rate can improve the importance of effective friction in mixing and prolong the service life of wear-resistant plate.

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: In this study, a elasto-plastic constitutive model of friction incorporating the concept of superloading surface was developed based on the subloading friction model. The proposed model achieves a smooth transition of friction by describing the evolution rule of structure, treating the state with static friction coefficient larger than kinetic friction coefficient as the bulkiness of structure. The positive definiteness of the plastic multiplier, loading condition, and material parameters were derived, and the validity of the proposed model in accordance with the subloading-friction model was confirmed through a stick-slip simulation of a mass-spring system.

Summary: This paper investigates the influence of preparation strategies on the lubrication properties of surface textures. Three laser scanning strategies are proposed to achieve a sinusoidal textured surface, and the evolution of surface structure and chemical composition is discussed. The findings show that ridge structures enhance anti-wear properties but also increase the friction coefficient. However, the oil cover preparation method prevents the formation of ridges and improves wettability.

Summary: This study presents a systematic approach to generating control signals for a tactile simulator that simulate the touch of textile fabrics. By using a friction modulation tactile surface and acquiring forces from real surfaces with artificial finger mimicking fingerprints, control signals are generated and processed in the frequency domain before sending them to the tactile stimulator. The study focuses on the potential benefits of incorporating fingerprint information in fabric simulations to achieve a more realistic tactile perception. A sensory analysis with 36 participants using the generated control signals showed better discrimination without fingerprint information.
