Summary: In this paper, the use of recycled carbon fibers (rCFs) in cement composites was investigated. It was found that although the regained CFs had fewer oxygen-containing groups on the surface compared to virgin CFs, they exhibited better adhesion and pullout resistance. The incorporation of rCFs into cement-based composites resulted in a significant increase in flexural and compressive strengths, especially for rCFs with a higher degree of depolymerization.

Summary: The combination of chemical swelling and electrochemical oxidation in DMSO at normal temperature and pressure successfully achieved the separation and recovery of carbon fibers from CFRP. The depolymerization rate of epoxy resin in CFRP increased with increasing ammonium acetate concentration and current density, with the latter having a more significant influence. The recycled carbon fibers showed few residual resin on their surfaces and achieved a tensile strength and interfacial shear strength close to that of the original fibers.

Summary: With the increase in waste rubber products, the pressure on the environment and resources is becoming more serious. The use of reclaimed rubber (RR) is a practical method to address this challenge. This study explores the reinforcement behavior of RR when different contents of natural rubber (NR) matrix are replaced by RR. The results show that the crosslinking density, Payne effect, and modulus increase with the increase in RR content until 60 phr, but decreases at 80 phr. SEM observation confirms that both NR and RR constitute co-continuous phases at 60 phr, while RR becomes the only continuous phase at 80 phr. The curing rate is also enhanced with higher RR content, and structures with high crosslinking density are found in the NR matrix filled with RR. Furthermore, carbon black in RR, high crosslinking density, and a continuous rubber matrix are important factors influencing the reinforcement behavior in RR filled rubber composites.

Summary: In-situ polymerization of sodium acrylate (SA) in cementitious composites significantly improves their flowability, strength, deformability, and water resistance. The addition of 4% SA in the modified cementitious composites (iPMCC) results in a 35.1% improvement in flowability, a 109.0% increase in flexural strength, an 11.8% increase in compressive strength, a 458.8% rise in flexural deformation energy, a 161.0% rise in compressive deformation energy, and a 19.1% decrease in water sorptivity compared to neat cement paste. The in-situ SA polymerizations refine the pores in the iPMCC, but the presence of macro defects is observed in the iPMCC with 8% SA. The formation of cross-linked sodium polyacrylate networks in the cement matrix enhances the strength, deformability, and water resistance of the iPMCC.

Summary: Elastomeric nanoparticles (ENPs) have different effects than carbon black (CB) on rubber composites. The study investigates their morphologies, viscoelasticity, mechanical properties, and interactions with rubber, revealing differences in dispersion states and reinforcing effects. Adding ENPs reduces free chain ends in rubber composites, decreasing rolling resistance and enabling the development of energy-saving tires. Compared to current techniques, adding ENPs to rubber composites provides a simpler and easier way to lower free chain ends. The study also shows a synergistic effect of ENPs and CB on rubber reinforcement, with an optimal ENP content of approximately 10 phr based on vulcanisate characteristics.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.
