Special Issue Information

Dear Colleagues,

Polymer composites are increasingly central to high-performance applications across sectors, from transportation, energy, and construction to consumer goods and emerging technologies. This Special Issue invites original research on advances in fiber-reinforced polymer composites, with a focus on materials design, interfacial phenomena, and scalable processing technologies. We encourage submissions addressing a wide range of fiber types, including glass; carbon; aramid; basalt; natural polymer fibers; ultra-high-strength monocrystalline fibers, such as silicon carbide; and high-performance polyethylene. The interactions between fiber architecture and polymer matrix structure, including thermosets and thermoplastics, crystallinity, cross-linking density, and contraction behavior, are a key determinant of composite performance and reliability.

A major theme of this Issue is fiber–matrix adhesion. We welcome investigations into chemical bonding, mechanical interlocking, reactive interface chemistry (e.g., acid treatments), and electrostatic effects. Contributions addressing the influence of fiber dimensions, orientation (random, unidirectional, orthogonal), surface preparation (e.g., organosilanes, phosphates, titanates), and polymer viscosity or wettability on adhesion and overall composite strength are encouraged. The relationships between microstructural parameters—such as fiber length, diameter, content, and spatial distribution—and mechanical properties, particularly tensile and impact strength, are also of interest. Studies that link interfacial engineering to durability, environmental resistance, or regulatory standards are highly relevant to both applied research and policy development.

We invite contributions on composite processing techniques, covering both established and emerging methods. For thermosetting systems, this includes manual lay-up, spray lay-up, vacuum infusion, the autoclave consolidation of prepregs, compression molding, pultrusion, sheet molding compounds, and filament winding. For thermoplastic composites, injection molding and extrusion are of particular interest, especially in relation to fiber dispersion, orientation, and interface control. Contributions bridging fundamental understanding and practical technology for large-scale manufacturing, performance standards, or life-cycle considerations are encouraged.

High-Temperature Tribological Behavior of Polyimide Composites with Dual-Phase MoS2/MXene Lubricants: A Synergistic Effect Analysis

Polyimide (PI), owing to its high heat resistance and low density, is often employed as a substitute for metallic materials in high-temperature environments, such as aircraft engines, bearings, and gears. However, the relatively high friction coefficient of pure PI limits its application under harsh conditions. Therefore, this study synthesized a composite lubricant with binary fillers to improve this performance. This study employed the hydrothermal method to synthesize MoS2/MXene composite lubricating fillers and systematically investigated the high-temperature tribological properties of PI composites reinforced with these fillers. The results demonstrated that the optimal PI composite containing 5% MoS2/MXene exhibited a 14 °C increase in initial decomposition temperature compared to pure PI. Additionally, its thermal conductivity was enhanced by 36%, while the hardness (0.398 GPa) and elastic modulus (6.294 GPa) were elevated by 12.4% and 18.6%, respectively, relative to the pure PI. In terms of tribological behavior, all composite formulations displayed typical temperature-dependent friction characteristics. It is worth noting that MXene’s high hardness and thermal conductivity inhibited the occurrence of abrasive wear. At the same time, the substrate was strengthened, and thermal resistance was enhanced, thereby delaying the plastic deformation of the material at high temperatures. Full article

Sulfur-containing polymers are unique sustainable materials with promise for the development of various adsorbents for environmental remediation. However, they have not been explored for CO2 capture despite reports on its ability to decontaminate various aqueous pollutants. This study reports on the single-step synthesis of a diamine-functionalized sulfur-containing copolymer by the thermally induced radical copolymerization of N2,N2-Diallylmelamine (NDAM), a difunctional monomer, with sulfur and explores its use for CO2 capture. The influence of reaction parameters such as the weight ratios of sulfur to NDAM, reaction temperature, time, and the addition of a porogen on the properties of aminated copolymer was investigated. The resulting copolymers were characterized using FTIR, TGA, DSC, SEM, XRD, and BET surface area analyses. The incorporation of NDAM directly imparted amine functionality while stabilizing the polysulfide chains by crosslinking, leading to a thermoset copolymer with an amorphous structure. The addition of a NaCl particle porogen to the S/NDAM mixture generated a mesoporous structure, enabling the resulting copolymer to be tested for CO2 adsorption under varying pressures, leading to an adsorption capacity as high as 517 mg/g at 25 bar. This work not only promotes sustainable hybrid materials that advance green chemistry while aiding CO2 mitigation efforts but also adds value to the abundant amount of sulfur by-products from petroleum refineries.

This study presents the development of a sustainable composite material by incorporating by-products from the cork industry into acrylonitrile butadiene styrene (ABS), with the aim of reducing the environmental impact of plastic composites while maintaining their performance. ABS, a petroleum-based polymer, was used as the matrix, and maleic anhydride (MAH) with dicumyl peroxide (DCP) served as a compatibilizing system to improve interfacial adhesion with cork microparticles. Composites were prepared with 10% w/w cork in various particle sizes and characterized via FTIR, X-ray computed tomography, SEM, mechanical testing, and thermal analysis. The best performing formulation (CPC-125) showed a reduction of only ~16% in tensile modulus and ~7% in tensile strength compared with ABS-g-MAH, with a more pronounced decrease in strain at break (3.23% vs. 17.47%) due to the cork’s inherent rigidity. Thermogravimetric and calorimetric analysis confirmed that thermal stability and processing temperatures remained largely unaffected. These results demonstrate the feasibility of incorporating cork microparticles as a bio-based reinforcing filler in ABS composites, offering a promising strategy to reduce the use of virgin plastics in applications compatible with conventional injection molding.
