Summary: This paper evaluates the abrasion resistance of a carbon fiber composite filled with layered-silicate clay nanoparticles. The study investigates the dispersion and performance of the clay-epoxy nanocomposite, and determines the optimal content for fiber composite production. The nanocomposite mixture is prepared by dispersing clay nanoparticles in the epoxy monomer, followed by vacuum infusion to produce the fiber reinforced composite. The presence of nanoclay reduces weight loss and damage on the impacted surface.

Summary: Novel sound insulation biocomposite materials using treated alfa fibers and sawdust wood fibers show great potential for sound absorption applications, with maximum sound absorption coefficient values of 0.98 at specific frequencies. The thickness of air gaps and additional woven flax shell layer have significant effects on low frequencies. The results indicate that these biocomposites could be an alternative to conventional materials for sound absorbing panels.

Summary: The addition of hybrid HA/GF filler has been shown to enhance the mechanical properties of the composite, such as tensile modulus and flexural modulus, while improving interfacial interaction. Furthermore, compared to adding HA alone, the hybrid HA/GF filler also increases the impact strength of the composite and reduces damping.

Summary: This study investigated the effect of rice fibers and nanoclay on soil's mechanism and mechanical performance. The results showed that increasing the dosage of rice fibers improved the shear and compressive strengths of the soil. The optimum amount of fibers was 0.9%, exceeding which led to fiber twisting and agglomeration. However, increasing the nanoclay content decreased the failure strain of the soil.

Summary: Biological materials formed by growing mycelium-forming fungal microorganisms on natural fibers can provide a solution to environmental pollution and scarcity of natural resources. This study investigates the effects of inorganic particles on mycelium materials and finds that nanoclay leads to decreased growth rate, reduced mechanical properties, and increased difficulties in degrading fibers.

Summary: The study explored using feather keratin resin as a crystallizable adhesive agent for wood fillers, resulting in a bio-based composite. While mechanically milled feathers easily resinified, limited molecular rearrangement was observed during hot-press compression molding. Sintering was found to effectively resinify milled feathers and induce recrystallization of feather keratin, improving mechanical properties of the composite.

Summary: This study investigated the effect of adding encapsulated healing agent with neat polymeric and nanocomposite shells on the mechanical-healing features of glass fibers/epoxy composite under various loads. The results showed that the composite with 3 wt% nanosilica on the surface of microcapsules achieved the highest healing efficiency of 83.9% under flexural loads. Increasing the weight fraction of silica nanoparticles had a negligible effect on the healing ability of the composite under tensile loading. The most important finding in this work was the achievement of 135.8% healing efficiency in the composite with 2 wt% nanosilica under shear loads.

Summary: A novel conductive composite material was developed using woven carbon nets, which not only transformed insulated particleboard into a highly conductive composite but also significantly improved its flexural properties. However, the presence of carbon nets had a negative impact on the internal bond strength and physical properties of the composites.

Summary: In this study, an antibacterial surface composed of thermoplastic poly-urethane (TPU) embedded with bentonite and MMT clay containing quaternary ammonium salts (QAS) was developed to prevent bacterial adhesion. The results showed that the nanoclay-embedded TPU surfaces with QAS significantly reduced the adhesion of E. coli and S. aureus, and a higher nanoclay concentration enhanced the effectiveness.

Summary: The study focuses on preparing cellulose nanocrystals (CNCs) reinforced composites using polyhydroxybutyrate (PHB) and polypropylene (PP). The effects of CNCs content and the addition of maleic anhydride (MA) on the mechanical and morphological properties were studied. The biodegradability of the composites was also investigated. The results showed that the environmental impacts of composites containing PHB are higher than those of PP.

Summary: The effect of pH on the extraction yield of phenolic compounds from liquid phases recovered after the hydrothermal treatment of black liquor was studied using batch and continuous reactors. It was found that reducing the pH slightly improved the extraction of phenol and guaiacol, but greatly increased the extraction yield of syringol. Lower pH also hindered the hydrolysis of ethyl acetate during liquid-liquid extraction. The experiments confirmed the superior performance of the continuous reactor and the degradation of phenolic products at higher treatment temperatures.

Summary: This study successfully fabricated plywood boards using virgin and recycled high-density polyethylene (vHDPE and rHDPE) films as formaldehyde-free adhesives, and achieved improved physical and mechanical properties by using PE-g-MA as a coupling agent. PE-g-MA played a crucial role in enhancing the interfacial bonding ability and stress propagation. The properties of plywood boards made with rHDPE were significantly improved, although the presence of impurities in the recycled film made the coupling agent less effective.

Summary: The present study aimed to minimize or eliminate the harmful effects of urea-formaldehyde (UF) resin by using recycled high-density polyethylene (HDPE) as a nontoxic adhesive. The results showed that HDPE films provided mechanical properties comparable to UF adhesive, even with lower adhesive content and pressing time. The optimum conditions were an HDPE loading of 240 g/m(2), a hot-pressing temperature of 160°C, and a hot-pressing time of 5 min. This study confirmed the potential of recycled HDPE as a promising adhesive for environmentally-friendly plywood manufacturing.
