Ultra-high toughness cementitious composites (UHTCC) are suitable for hydraulic structures due to their enhanced ductility and effective crack control capacity. This research investigated the dynamic tensile behavior of two different types of UHTCC: one featuring a normal strength matrix reinforced with polyvinyl alcohol (PVA) fibers, and another combining a high-strength matrix with polyethylene (PE) fibers. The findings revealed that water saturation effect on the dynamic tensile behavior of two types of UHTCC were opposite. After saturation, normal UHTCC made with PVA fibers exhibited increases in tensile strain capacity, while UHTCC made with PE fibers and high-strength matrix exhibited reduction in deformation by 56 %. Under dynamic tensile loading, moisture content notably affected the strain rate sensitivity of tensile properties in normal UHTCC with PVA fibers, demonstrating significant variations in DIF (Dynamic Increase Factor) for strength, deformation, and energy dissipation. However, these influences were minimal in composites made with a high-strength matrix and PE fibers. The mechanism for such phenomenon were discussed based on the result of matrix fracture test and fiber pull out test.

A hybrid-acid (HA) pickling method has been developed to remove rust from corroded steel components prior to localized strengthening with carbon-fiber-reinforced polymer. This study conducted a time-dependent assessment of the pickling reaction and steel-surface characteristics. The rust removal mechanism was hypothesized at the mesoscale and electrochemical levels. Furthermore, a comparative study among conventional blasting, power-tool grinding, and the HA method was performed via the surface characterization of steel substrates and deterioration tests on composite joints. The results demonstrated that the HA method has excellent applicability to corroded steel surface with pitting behavior, and exhibits good comprehensive performance regarding adhesion, surface morphology, and oxide residue. In addition, the pickling process of 1 h reduces over 70 % intrinsic salt residue, while pickling over 4 h facilitates the formation of decentralized pit craters that provide an anchoring effect for adhesive bonding. The bond strength of the corroded steel surface prepared by the HA method is comparable to that of the blasted surface with a difference of ±10 %. Moreover, it provides excellent water resistance at the bonded interface, and the bond strength of the CFRP-steel joint increased by 10–30 % due to its special mechanical interlocking properties. This study offers new insights into advancing the applicability of both the HA method and CFRP technique for corroded steel structures.

The intensifying global energy and environmental challenges urgently call for advanced materials characterized by low carbon emissions and sustainable development to meet this growing demand. Carbon fibre-reinforced polymers (CFRP) are increasingly favored across various sectors due to their exceptional lightweight and high-strength properties. However, traditional production and recycling processes for CFRP are hampered by high energy consumption and environmental pollution, which impede their progress toward sustainability. To address these issues, this review concentrates on the emerging technologies that promise to significantly reduce industrial energy consumption and emissions, particularly electromagnetic field-driven techniques. These methods can enhance every stage of the CFRP lifecycle, from precursor preparation and interfacial construction to rapid composite fabrication and efficient recycling. This paper first outlines the distinct advantages of these emerging technologies, followed by a discussion of their specific applications and recent advancements in CFRP production. Finally, it provides an in-depth analysis of the industrial challenges and future opportunities for broader application. We anticipate that electromagnetic field-driven technologies will establish a new paradigm in composite manufacturing, and as science and technology progress, these methods will be instrumental in fostering the green manufacturing of CFRP and supporting sustainable practices across multiple domains.

Honeycomb structures are widely used in engineering due to their excellent mechanical properties and lightweight design. However, their discrete heterogeneity creates significant challenges in mechanical analysis and design. Over recent decades, substantial advancements have been made in predicting honeycomb performance. This review systematically explores these developments, emphasizing the theoretical analysis of their linear, nonlinear, and non-uniform properties. It provides a detailed review of analytical models, numerical simulation methods, and experimental validations, emphasizing the critical importance of comprehensive and high-quality datasets in enhancing the understanding and prediction of honeycomb behavior under varied conditions.
Despite these advancements, challenges persist. Current models often lack generality, require extensive high-quality datasets, and face high computational costs in complex engineering applications. Accurate modeling of material heterogeneity and integrating multi-scale effects remain unresolved, limiting the broader application of honeycomb structures.
Looking forward, integration of machine learning with artificial intelligence is anticipated to enhance model accuracy and computational efficiency. Developing universal datasets for diverse honeycomb materials and adopting hybrid simulation-experiment approaches will help address complex engineering challenges.
This review emphasizes the need for adaptable models, data-driven techniques, and efficient computational frameworks. It provides a comprehensive overview of recent progress, persistent challenges, and emerging trends, offering valuable insights to guide future research and engineering applications.

This work investigates the fatigue behavior of satin fabric-woven carbon fiber-reinforced poly-ether-ketone-ketone (PEKK) laminates under low (20 Hz) and ultrasonic (20 kHz) testing frequencies using identical specimen geometries. Specimen designs across all orientations were based on modal, harmonic, static-structural, and buckling analyses to ensure comparable results. This design enables uniaxial tension–compression loading of woven carbon-fiber reinforced polymers (CFRPs) to fail in the gauge section without global buckling and ensures overlapping stress amplitudes between the two test systems. The maximum possible stress amplitudes of ultrasonic fatigue testing (UFT) are higher than the lowest stress amplitudes that cause failure in the conventional servo-hydraulic (SH) system. By using the anisotropy of composite laminates, this design was validated through tension–compression experiments on dogbone-shaped specimens with four fiber orientations: 0°, 15°, 30°, and 45°, using SH and UFT systems. Results comparing high-cycle fatigue (HCF) and very high-cycle fatigue (VHCF) behavior of angle-ply laminates indicate a strong dependence on fiber orientation. A comparison of self-heating and microscopic analysis between the two systems demonstrates the applicability of UFT for off-axis VHCF characterization of woven composites. Finally, shear stress-induced damage initiation in 0°fiber-oriented dog-bone-shaped specimens, as observed in this work and reported in the literature, is addressed as a multi-axial stress state problem by incorporating the resultant normal, transverse, and shear stresses into the Tsai–Wu formulation.

This research identifies and systematically evaluates the reactivity of crystal and amorphous phases of five typical ceramic waste powders (CWP) based on selective chemical dissolution and quantitative X-ray powder diffractometry. The alkali-activity classification of mineral components of ceramic waste is identified. Four principal components are amorphous phase (glass mainly composed of Si and Al), reactive crystals mica, partially reactive feldspars, and inert crystals quartz and mullite. Their leaching kinetics of ceramic wastes in NaOH solution are studied. For geopolymer production, the amorphous phase is the main reactant phase. The average activation energy for the leaching of Si and Al is 103.49 and 90.01 kJ/mol, respectively. Based on the reaction kinetics, a rapid evaluation of the ceramic waste-alkali reactivity is proposed given individual leaching ratio of Si and Al. Besides, another simple assessment method based on the geometrical specific surface area (SSA) is provided for rough assessment of activity at room temperature. There is a good correlation between the order of reactivity ranking and the compressive strength of alkali-activated paste containing CWP. The reactivity evaluation methods are of great value to the application of CWP in production practice.

Due to the rapid development of electronic devices, there was an urgent need for polymer composite materials with excellent heat dissipation capabilities to solve the heat dissipation problem of electronic devices. However, designing an insulation composite material with simple processing methods, low cost, and high thermal conductivity and excellent mechanical properties remained a challenge. Inspired by the human nervous system, this article used cellulose nanofibers (CNF) as a template and adsorb hydroxylated boron nitride nanosheets (BNNS–OH) through a simple electrostatic self-assembly method, and prepared composite film through vacuum filtration. The BNNS-OH@CNF composite film generated a thermal conduction network similar to the human nervous system, and can achieve a maximum thermal conductivity of 10.7 W m−1 K−1 when the filler load was 60 wt%. It had good electrical insulation performance and a volume resistivity of 7.7 × 1013 Ω m. The most important thing was that the tensile strength of 34.2 MPa can still be maintained at such a high filler load. In addition, the composite film also exhibited good thermal management capabilities. This had significant application potential as a thermal management material.

Osteoporosis (OP) is characterized by diminished bone mass and increased skeletal fragility, representing a metabolic disorder. Osteoporotic bone defects (OBD) pose significant treatment challenges due to the active generation of osteoclasts (OCs) and the suppression of osteogenic differentiation. These complications impose a substantial burden on patients and the healthcare system. To address this issue, alendronate sodium (AS) was incorporated into Gelatin methacryloyl (GelMA), and then loaded with ligustrum officinale polysaccharide (LOP) to form GelMA-AS-LOP microspheres. These multifunctional hydrogel microspheres, characterized by their abundant void structures, offered continuous drug release. GelMA-AS-LOP suppressed OCs’ activity and formation, enhanced osteogenic differentiation and mineralization, and exhibited low visceral toxicity. Consequently, they ameliorated the pathological microenvironment associated with OP and facilitate OBD regeneration. The hydrogel microspheres achieved this by promoting osteogenesis and modulating the NFATc1, RANKL (via LOP), and MAPK (via AS) signaling pathways, resulting in a dual synergistic effect.

Silicone elastomers with unique inorganic/organic molecular structures are widely used in many fields, but it has proven to be a critical challenge to achieve a trade-off between mechanical strength and heat resistance; for example, modifying elastomers by improving chains’ interactions produces enhanced strength/stretchability but inevitably causes significant loss in their thermal stability. Herein, we circumvent this inherent trade-off issue by incorporating multiple reversible dynamic bonds with high-temperature resistant features into a cross-linked polydimethylsiloxane (PDMS) network. Typically, appropriate imine bonds, boroxine bonds and coordination bonds are employed and optimized to construct PDMS molecular networks. Consequently, the resulting PDMS elastomers not only have 7–30 times increase in tensile strength and toughness compared with traditional PDMS elastomers, but also present exceptional healable and reprocessable performance (>95 % strength recovery) and maintain excellent high-temperature resistance (e.g., temperature at 5 wt% weight loss of ∼354 °C), superior to the previous modified silicone elastomers. Further, optimizing the size and content of thermally conductive fillers (Al2O3), the thermal conductivity of silicone composite reaches 0.8 W/mK, vitalizing the rapid heat conduction and dissipation. Moreover, the composite can be repeatedly self-healed and reprocessed, its tensile strength recovers 91 % and 93 %, demonstrating their efficient and healable thermal management. In addition, the composites maintain excellent high-temperature resistance (e.g., temperature at 5 wt% weight loss of ∼388 °C). This study provides a straightforward method for the preparation of thermal interface materials with strong, high-temperature resistant and self-healing materials for promising thermal management applications.

Typically, appropriate imine bonds, boroxine bonds and coordination bonds are employed and optimized to construct PDMS molecular networks. Consequently, the resulting PDMS elastomers not only have 7–30 times increase in tensile strength and toughness compared with traditional PDMS elastomers, but also present exceptional healable and reprocessable performance (>95 % strength recovery) and maintain excellent high-temperature resistance (e.g., temperature at 5 wt% weight loss of ∼354 °C), superior to the previous modified silicone elastomers. Further, optimizing the size and content of thermally conductive fillers (Al<sub>2</sub>O<sub>3</sub>), the thermal conductivity of silicone composite reaches 0.8 W/mK, vitalizing the rapid heat conduction and dissipation. Moreover, the composite can be repeatedly self-healed and reprocessed, its tensile strength recovers 91 % and 93 %, demonstrating their efficient and healable thermal management. In addition, the composites maintain excellent high-temperature resistance (e.g., temperature at 5 wt% weight loss of ∼388 °C). This study provides a straightforward method for the preparation of thermal interface materials with strong, high-temperature resistant and self-healing materials for promising thermal management applications.</div></div>","PeriodicalId":10660,"journal":{"name":"Composites Part B: Engineering","volume":"295 ","pages":"Article 112205"},"PeriodicalIF":12.7,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143372042","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Current tissue-engineered scaffolds (TES) for cartilage regeneration have limited clinical application due to the challenges of complex fabrication methods and high production costs. This study presents the development of porous scaffolds derived entirely from egg white (EW), using a straightforward combination of lyophilization and thermal crosslinking. The objective was to create an ideal TES with a simple fabrication process, low cost, and high shape precision, making it suitable for clinical use. EW was blended with deionized water in various proportions to optimize scaffold properties. The resulting porous EW scaffolds exhibited adjustable pore size, porosity, mechanical strength, degradability, and hydrophilicity. Notably, thermal crosslinking significantly improved structural stability, enhanced mechanical properties, and slowed the degradation rate of the scaffolds. Biocompatibility testing revealed that the porous EW scaffolds supported excellent chondrocyte adherence and exhibited good biocompatibility. Subcutaneous implantation in rats demonstrated that the scaffolds were immunologically inert. Both in vitro and in vivo cartilage formation assays confirmed that the EW scaffolds facilitated the generation of cartilage-like tissue, featuring cartilage-specific matrix components and appropriate mechanical strength. Furthermore, the EW scaffolds were easy to fabricate into various shapes, displayed excellent shape retention, and supported precise cartilage regeneration after subcutaneous implantation. These features underscore their potential for creating tailored scaffolds for complex cartilage repair. In conclusion, this study provides a simple, cost-effective method for producing porous EW scaffolds with tunable shapes and properties, highlighting their promise for clinical cartilage regeneration applications.
