Summary: A series of small molecules containing alkenes were electrografted onto carbon fibers surface using in situ generation of aryldiazonium salts. This surface modification approach utilizing ROMP showed significant increases in interfacial shear strength (IFSS) of up to 189%. Dilution of strained norbornene alkenes at different ratios still resulted in improved IFSS gains compared to pristine fibers, demonstrating the potential of ROMP for tailoring the surface chemistry of carbon fibers for advanced composites.

Summary: The interfacial adhesion and failure mechanism of carbon fiber reinforced polyimide (CF/PI) composites were investigated through micro-bond tests. High-temperature treatments showed that the interfacial shear strength (IFSS) initially increased and then decreased with increasing temperature, with composites formed by KH500 exhibiting higher performance retention. The IFSS results of composites formed by KH308 and KH500 after long-time treatments were significantly different, indicating the proper service temperature of CF/PI composites. Despite decomposition during the curing process, sizing agents still enhanced the active functionality on fiber surfaces, contributing to the interfacial adhesion of CF/PI composites at high temperature.

Summary: Lignin obtained from wood is an abundant and renewable carbon resource for energy storage, but its unfavorable processing conditions and limited performance hinder its use as supercapacitor electrodes. In this study, plasma treatment was used to enhance the electrochemical performance of lignin-based carbon fibers. The treatment increased the electrode's capacitance by 20% and improved its rate capability and energy-power performance. The introduction of desirable functional groups through plasma treatment also enhanced the long-term cycling stability and self-discharge characteristics of the device. Investigation was also conducted on the effects of different oxygen surface functional groups on the capacitive performance of the fibers under different conditions.

Summary: The tribological performance of carbon-fiber-reinforced polymer (CFRP) incorporated with different content of graphite nanoplatelets (GNPs) was investigated. The orientation of GNPs in the in-plane direction increased with the increase of GNPs content due to high pressure compression molding, which facilitated the formation of GNPs tribofilm during friction. The results of friction experiments showed significant reductions in friction coefficient (44.7%) and wear rate (77.8%) for the CFRP with 15 wt% GNPs.

Summary: This research focuses on improving the mechanical properties of carbon fiber-reinforced linear low-density polyethylene composites. The adhesion of the PE matrix is enhanced through oxygen plasma treatment. The best tensile results were observed with a plasma-treated PE/10 wt.% CF combination. The addition of carbon fibers at higher percentages resulted in a reduction in tensile strength. The fabrication condition of 180 degrees C temperature for 20 min showed the best tensile properties.

Summary: Carbon fibers are widely used in automotive, aerospace and energy industries due to their low weight and high strength. However, their significant cost and release of toxic substances during carbonization are challenges. Bio-sourced cellulose materials and eco-friendlier plasma carbonization technologies can help overcome these challenges, leading to efficient carbon fibers with good mechanical properties.

Summary: This paper develops a novel approach to determine the fiber/matrix interfacial shear strength (IFSS) in a polymer composite with carbon fiber roughness and the presence of carbon nanotubes (CNTs). The carbon fiber surface exhibits multi-scale asperities, which are modeled using Fourier series decomposition to capture surface roughness. Molecular Dynamics (MD) simulations are used to determine the interfacial shear strength of different surface asperities. The results show that the presence of CNTs enhances the IFSS by about 19%.

Summary: This study experimentally investigated the effects of O-2 plasma pretreatment on the grafting of amino functional groups onto CFs. It was found that the degree of oxidation was positively correlated with the grafting efficiency, and the results depended on the formation of unsaturated C, C-OH, and O=C-OH groups during the oxidation process. The earlier oxidation process can be controlled to regulate the ammonia grafting of CF.

Summary: This study analyzed the application of waste wood as a supercapacitor electrode material. Cellulose fibers were extracted from waste wood and mixed with graphene nanoplatelets (GnPs) to prepare carbon papers. The increase in GnPs content decreased the surface areas and specific capacitance of the carbon papers, but increased their capacitive performance.

Summary: The capacitive properties of nitrogen-doped electrospun carbon fibers are influenced by different surface modification methods. Hydrothermal treatment increases the nitrogen content on the fiber surface but decreases the specific surface area and pore volume, resulting in lower capacitance compared to nitrogen plasma treatment.

Chemical analysis revealed that plasma pre-treatment introduced polar oxygen-containing groups. Furthermore, optimized plasma activation was found to mitigate adhesion differences between distinct surface structures.

Summary: The treatment of spine tumors is personalized and multimodal, often involving surgery followed by radiation therapy. Carbon-based materials, such as CFR implants, have shown to be promising alternatives to traditional titanium implants in terms of radiolucency and biocompatibility, with potential benefits for patients. Further trials are needed to assess their impact on local tumor control.

Summary: The addition of nanoclay can improve the moisture barrier property of carbon/epoxy composites, leading to better mechanical and thermal performance in seawater. By adding 2% nanoclay, the composite shows reduced moisture absorption, decreased compressive strength and modulus, but still exhibits improved bonding properties compared to the base one after exposure to seawater.

Summary: The demand for structural materials with high strength, lightweight, corrosion resistance, and environmental resistance has led to the consideration of fiber-reinforced polymer composite (FRPC) materials over traditional materials. Synthetic nanoparticle-reinforced FRPC materials have shown superior performance in various high-end applications. Incorporating nanoparticles, such as montmorillonite nanoclay (MMT) and graphene nanoplatelets (GNP), in carbon fiber-reinforced epoxy composites improves the dynamic mechanical properties, particularly the glass transition temperature. The frequency sweep dynamic mechanical analysis (DMA) test reveals that nanophased FRPCs have a higher storage modulus compared to unmodified samples, indicating their frequency-dependent properties.
