Summary: The performance of a thermoreversible epoxy vitrimer and its carbon fiber composites, which contains a metal catalyst (Zn2+), was investigated focusing on the healing capability of the system. The analysis showed increased molecular mobility above a topology freezing temperature (T-v), but the reinforcement phase inhibited the flow capability, reducing the flow. The repairability of the vitrimeric CFRP was unsatisfactory, and the healing efficiency of the modified epoxy composites was about 84% of the lap shear strength of the pristine system.

Summary: This study investigates the use of short bagasse fibers to reinforce cement composites and promote recycling of sugarcane residues. The addition of stearic acid and castor oil as fiber modifiers improves the hydrophobic character of the fibers. Experimental design shows that composites with 2 wt% stearic acid-treated fibers achieve optimal mechanical and physical properties. Mechanical responses increase by up to 22.25%, while physical responses reduce by up to 20.46% compared to a reference mortar.

Summary: PLA/sugarcane bagasse fiber composites prepared by injection molding show significant attrition in fiber length and diameter during processing, resulting in fibers of similar dimensions. The interfacial adhesion between PLA and bagasse is good, and coupling agent has minimal effect on properties. Fiber fracture and shear yielding contribute to increased impact resistance.

Summary: Electrothermal processes were investigated in pyroresistive composites of high-density polyethylene with carbon black and carbon fibers. The kinetic heating curves showed an exponential dependence with a heating rate constant for each composite. Equilibrium temperature was reached after a short heating time, and decreased with the presence of positive temperature coefficient of resistance (PTC) effect. The composites exhibited self-regulating capability and the equilibrium temperature depended on the applied voltage and electric power with different relationships. An application of using HDPE-CB composite as a heating element for resistance welding was demonstrated.

Summary: Expenditure isolation of lignin and the understanding of its structural variations during different isolation processes are crucial for the high-value utilization of lignin. This study proposed a green deep eutectic solvent (DES) consisting of choline chloride, ethylene glycol, and 4-chlorobenzene sulfonic acid for rapid lignin separation from poplar. The structural variations of DES lignin and its relationship with alkali pre-extraction of hemicellulose were investigated. The results showed that alkali pretreatment enhanced the DES separation of lignin and promoted the cleavage of specific linkages, resulting in reduced molecular weight and thermal stability of isolated DES lignin. Moreover, DES lignin obtained from integrated utilization displayed higher purity and S/G ratio compared to lignin obtained from direct DES treatment.
