Three tensegrity solutions are explored: super-structures, sub-structures, and cable-structures. The basic units of the three kinds are first studied, where we analytically calculate the minimal mass required, along with the optimal inclinations angles, to sustain a simply supported load. By applying self-similar rules and varying the structure subdivisions and complexities, the structure mass is further minimized under bar-yielding and buckling constraints. This study finds the optimal complexities and subdivisions of the three solutions. Numerical results validate and compare the minimal mass designs. These proposed lightweight designs are applicable to bridge designs and other scenarios that undergo simply supported loads.本研究提出了使用张拉整体范式的简支问题的轻量化设计。探讨了三种张拉整体解：上部结构、下部结构和索结构。首先研究了这三种类型的基本单位，在那里我们分析计算所需的最小质量，以及最佳倾斜角，以维持一个简单的支持负载。通过应用自相似规则，改变结构细分和复杂程度，在杆屈服和屈曲约束下进一步减小结构质量。本文找到了三种解的最优复杂度和细分。数值结果验证和比较了最小质量设计。这些建议的轻量级设计适用于桥梁设计和其他承受简支载荷的场景。Structural integrity issues of composite materials and structures in advanced transportation equipmentYing Lin, Weijian Qian, Liming Lei, Yuexun Liu, Jingcao Zhang, Junjiang Liu, Weiyi Kong, Yanan Hu, Yaojun Shi, Zhengkai Wu, Hu Liu, Shengchuan Wudoi:10.1016/j.compstruct.2025.118943先进运输设备中复合材料和结构的结构完整性问题The rapid advancement of modern transportation systems has spurred a huge demand for low cost, lightweight, and high reliability composite materials, primarily owing to their high specific strength, design flexibility, and superior resistance to corrosion and high temperature, which makes them ideal alternatives to traditional metallic structures. Our work presents a thorough state-of-art review of the recent research and development progress of composite materials primarily in aerospace, rail transit, and automotive industries. Before addressing the application progress, some representative failure criteria have been introduced, providing the understanding and reference to the damage identification and fatigue life prediction. Despite significant advantages, the widespread integration of composite structures into modern transportation systems presents both a substantial challenge and a promising opportunity. Particularly, the structural integrity issues of composite structures have received more and more attention in engineering applications and assessment approaches, mainly in connection with failure constitutive laws, manufacturing considerations, extreme service conditions, structural health monitoring, repair and recycling, etc. An overview of the development of advanced composites within transportation systems is therefore provided, serving a reference for scientists and engineers.现代交通运输系统的快速发展刺激了对低成本、轻量化和高可靠性复合材料的巨大需求，主要是因为它们具有高比强度、设计灵活性和优越的耐腐蚀性和耐高温性，这使它们成为传统金属结构的理想替代品。我们的工作对复合材料的最新研究和开发进展进行了全面的回顾，主要应用于航空航天、轨道交通和汽车工业。在介绍应用进展之前，介绍了一些具有代表性的失效准则，为损伤识别和疲劳寿命预测提供理解和参考。尽管具有显著的优势，但将复合材料结构广泛集成到现代交通系统中既提出了重大挑战，也带来了充满希望的机遇。特别是，复合材料结构的结构完整性问题在工程应用和评估方法中越来越受到重视，主要涉及失效本构规律、制造考虑、极端使用条件、结构健康监测、修复和回收等方面。因此，提供了先进复合材料在运输系统中的发展概况，为科学家和工程师提供了参考。Composites Part A: Applied Science and ManufacturingStructural and hetero-interfacial engineering of magnetic bimetallic composites based polyurethane microwave absorbing coating for marine environmentQiaoqiao Han, Junhuai Xu, Jianyang Shi, Mi Zhou, Haibo Wang, Liang Geng, Junjie Xiong, Zongliang Dudoi:10.1016/j.compositesa.2025.108770海洋环境用磁性双金属复合聚氨酯吸波涂料的结构与异质界面工程Construction of microwave-absorbing materials adapted to marine application scenarios remain a challenge. Herein, environmentally stable CoxNiy@C absorbers are fabricated. The CoNi-C heterogeneous interface in these absorbers induces a more inhomogeneous space charge distribution than Co-C and Ni-C interfaces, contributing to strong hetero-interfacial polarization and thereby improving microwave absorption performance. The C2 absorber demonstrated an EAB of 5.68 GHz, covering the entire Ku-band at a thickness of 1.98 mm. Additionally, simulations revealed an excellent radar stealth effect in unmanned aerial vehicle (UAV) mode. The 3D graphite skeleton of the absorber can extend the diffusion path of corrosive media and facilitate bacterial deposition, producing synergistic anti-corrosion and antibacterial effects. After immersion in a 3.5 % NaCl solution for 47 days, the |Z|0.01Hz value of polyurethane (PU)/C2 coating remained at 6.32 × 108 Ω cm2, indicating superior anticorrosion characteristics. The antibacterial rates of C2 reached 99.77 % against Escherichia coli and 99.11 % against Staphylococcus aureus. This work offers fresh concepts for the development of next-generation multifunctional microwave absorbents.构建适合海洋应用场景的吸波材料仍然是一个挑战。在此，制造了环境稳定的CoxNiy@C吸收剂。与Co-C和Ni-C界面相比，这些吸收剂中的CoNi-C非均相界面诱导了更不均匀的空间电荷分布，导致了强的异质界面极化，从而提高了微波吸收性能。C2吸收体的EAB为5.68 GHz，覆盖整个ku波段，厚度为1.98 mm。此外，仿真结果表明在无人机模式下具有良好的雷达隐身效果。吸收剂的三维石墨骨架可以延长腐蚀介质的扩散路径，促进细菌的沉积，产生协同的防腐和抗菌效果。在3.5% % NaCl溶液中浸泡47 天后，聚氨酯(PU)/C2涂层的|Z|0.01Hz值保持在6.32 × 108 Ω cm2，具有较好的防腐性能。C2对大肠杆菌和金黄色葡萄球菌的抑菌率分别为99.77 %和99.11 %。这项工作为下一代多功能微波吸收剂的开发提供了新的概念。Composites Part B: EngineeringOptimization of interfacial adhesion and mechanical performance of flax fiber-based eco-composites through fiber fluorination treatmentOlivier Téraube, Jean-Charles Agopian, Monica Francesca Pucci, Pierre-Jacques Liotier, Pierre Conchon, Éric Badel, Samar Hajjar-Garreau, Honorine Leleu, Jean-Baptiste Baylac, Nicolas Batisse, Karine Charlet, Marc Duboisdoi:10.1016/j.compositesb.2025.112228通过氟化处理优化亚麻纤维基生态复合材料的界面附着力和力学性能Natural fibers, such as flax, are more and more used as biobased reinforcement for eco-composites manufacturing but their natural polarity makes them incompatible with most polymers (mostly dispersive). Nowadays, treatments such as torrefaction are known to reduce the polarity of natural fibers and thus increase the mechanical performance of the reinforced composites. However, these treatments could harm fibers and limit the gain in performance. Thereby, the use of a controlled fluorination treatment allowed, via the grafting of fluorine on the fiber surface, to decrease the polarity of these fibers while maintaining an equivalent Young's modulus and limiting the reduction of at break performance to just ∼30%. Therefore, by incorporating these fluorinated reinforcements in an epoxy matrix and by mechanically testing these composites, not only superior mechanical performances to those reinforced by raw fibers, but also superior to torrefied fiber-reinforced composites were measured, e.g.: the flexural modulus increased by 25% after fluorination vs. 10% after torrefaction and the flexural strain at break was enhanced by 10% after fluorination vs. decrease by 35% after torrefaction).天然纤维，如亚麻，越来越多地被用作生态复合材料制造的生物基增强材料，但其天然极性使其与大多数聚合物（主要是分散性的）不相容。如今，诸如碳化之类的处理方法可以降低天然纤维的极性，从而提高增强复合材料的机械性能。然而，这些处理可能会损害纤维并限制性能的提高。因此，使用受控氟化处理，通过在纤维表面接枝氟，可以降低这些纤维的极性，同时保持等效的杨氏模量，并将断裂性能的降低限制在30%左右。因此，通过在环氧基中加入这些氟化增强材料，并对这些复合材料进行机械测试，不仅测量了比原纤维增强的复合材料更优越的机械性能，而且也测量了比碳化纤维增强复合材料更优越的性能，例如：氟化后弯曲模量增加25%，而碳化后增加10%，断裂时弯曲应变增加10%，而碳化后减少35%)。Study on moulding control factors to reduce void contents in manufacturing CFRP parts by HP-RTMManseok Yoon, Minsu Ahndoi:10.1016/j.compositesb.2025.112231利用HP-RTM法降低CFRP零件孔隙率的成型控制因素研究Research and development efforts are ongoing to apply Carbon Fiber Reinforced Plastic (CFRP) to the automotive industry for weight and exhaust gas reduction. Among the available manufacturing processes, High Pressure Resin Transfer Molding (HP-RTM) stands out as the most suitable for mass production due to its cost efficiency, cycle time, and moldability. However, concerns over void formation and quality reliability have limited its application in Advanced Air Mobility (AAM). This study investigates control factors that can reduce void content in CFRP parts manufactured via HP-RTM. By comparing classical Resin Transfer Molding (RTM) with HP-RTM, a key control factor is identified, and changes in void content and static properties are observed across varying factors. The study concludes that while increasing molding pressure minimally affects absolute void content, it slightly increases relative void content due to reduced product thickness. Additionally, higher internal release agent content and resin injection velocity increase void formation due to altered flow dynamics. However, using a nip edge reduces void size and variation, ensuring more consistent product quality. By optimizing key factors such as vacuum, normal pressing force, and injection parameters in HP-RTM, void content can be consistently maintained at 1% or lower. These findings will contribute to the practical application of HP-RTM in the AAM industry and provide valuable insights into the manufacturing process of CFRP parts.将碳纤维增强塑料（CFRP）应用于汽车工业以减轻重量和减少废气排放的研究和开发工作正在进行中。在现有的制造工艺中，高压树脂传递模塑（HP-RTM）因其成本效率、周期时间和可塑性而最适合大规模生产。然而，对空泡形成和质量可靠性的担忧限制了其在先进空中机动（AAM）中的应用。本研究探讨了通过HP-RTM工艺降低CFRP零件空隙率的控制因素。通过比较经典树脂传递成型（RTM）和HP-RTM，确定了一个关键的控制因素，并观察了不同因素下孔隙含量和静态性能的变化。研究表明，增加成型压力对绝对空穴含量的影响最小，但由于产品厚度的减小，相对空穴含量略有增加。此外，由于流动动力学的改变，较高的内脱模剂含量和树脂注入速度增加了孔隙的形成。然而，使用压边可以减少空隙尺寸和变化，确保更一致的产品质量。通过优化HP-RTM中的真空、法向压力和注射参数等关键因素，孔隙率可以始终保持在1%或更低。这些发现将有助于HP-RTM在AAM行业的实际应用，并为CFRP零件的制造过程提供有价值的见解。Mechanical bionic compression resistant fiber/hydrogel composite artificial heart valve suitable for transcatheter surgeryYajuan Wang, Yuxin Chen, Wenshuo Wang, Xiaofan Zheng, Shiping Chen, Shengzhang Wang, Fujun Wang, Lu Wang, Yongtai Hou, Chaojing Lidoi:10.1016/j.compositesb.2025.112234适用于经导管手术的机械仿生抗压纤维/水凝胶复合人工心脏瓣膜The heart valve is a key structure for human blood circulation, and the development of artificial heart valves (AHVs) has become one of the research hotspots in the field of cardiovascular diseases. Compared to the vulnerability of biological valves to compression damage in transcatheter aortic valve replacement surgery (TAVR), polymer valves have shown superior performance in research. However, its structural differences from natural valves have limited its development. In this study, polycaprolactone gelatin (PCL-Gel) co-spinning directional nanofibers (FIB) were used to construct a three-layer structure of orientation layer-random layer-orientation layer imitating natural valves. Then, PCL-Gel/PAAm-co-PAA-Fe composite (COM-Fe) was prepared by iron ion crosslinking the oriented fiber membrane wrapped by polyacrylamide polyacrylic acid copolymer hydrogel (COM). The COM-Fe material has anisotropy similar to that of native valves and fully meets the thickness requirements for transcatheter surgery. In vitro simulated compression results showed that the COM-Fe material has no significant structural or strength loss after short-term curling compression. In vitro fluid dynamics results showed that the COM-Fe samples could fully achieve the parameters specified in ISO 5840-3:2021. In addition, COM-Fe materials showed excellent biocompatibility both in vitro and in vivo, and demonstrated anti-inflammation potential in a rat subcutaneous embedding model. It can be seen that biomimetic COM-Fe composite materials with good curling compression resistance and valve function have great potential for application in the direction of transcatheter AHVs.心脏瓣膜是人体血液循环的关键结构，人工心脏瓣膜的研制已成为心血管疾病领域的研究热点之一。与经导管主动脉瓣置换术（TAVR）中生物瓣膜易受压迫损伤相比，聚合物瓣膜在研究中表现出更优越的性能。但由于其结构与天然阀门的差异，限制了其发展。本研究采用聚己内酯明胶（PCL-Gel）共纺定向纳米纤维（FIB），构建了模拟天然阀门的定向层-随机层-定向层三层结构。在聚丙烯酰胺-聚丙烯酸共聚物水凝胶（COM）包裹的定向纤维膜上，采用铁离子交联法制备了PCL-Gel/PAAm-co-PAA-Fe复合材料（COM- fe）。COM-Fe材料具有与天然瓣膜相似的各向异性，完全满足经导管手术的厚度要求。体外模拟压缩结果表明，COM-Fe材料在短期卷曲压缩后没有明显的结构和强度损失。体外流体动力学结果表明，COM-Fe样品可以完全达到ISO 5840-3:2021中规定的参数。此外，COM-Fe材料在体外和体内均表现出良好的生物相容性，并在大鼠皮下包埋模型中显示出抗炎症的潜力。由此可见，具有良好卷曲抗压性和瓣膜功能的仿生COM-Fe复合材料在经导管ahv方向具有很大的应用潜力。Machine learning-driven interfacial characterization and dielectric breakdown prediction in polymer nanocompositesQi Wang, Wanxin He, Yuheng Deng, Yue Zhang, Wen Kwang Chern, Zepeng Lv, Zhong Chendoi:10.1016/j.compositesb.2025.112226 机器学习驱动的聚合物纳米复合材料界面表征和介电击穿预测The development of polymer nanocomposites has emerged as a promising approach for achieving higher-density energy storage. However, challenges in directly characterizing the interface between the matrix and nanoparticles, a pivotal factor for performance enhancement, have led to a shortfall in effective modeling methods. In this work, we propose a novel interfacial modeling approach that quantitatively describes the continuous transition of dielectric properties across the interface, capturing the inhomogeneous nature observed experimentally. A finely tuned Polynomial Chaos Neural Network (PCNN) with a determination coefficient exceeding 0.999 is developed to elucidate the relationship between model parameters and nanocomposite permittivity. The finite element model employing the proposed interface model demonstrates improved accuracy in predicting the permittivity of various nanocomposite systems with a physical insight into the interface. Built upon the interface model, a developed phase field model is then incorporated to investigate the dielectric breakdown mechanism in nanocomposites, highlighting the interface’s capacity to repel the breakdown path. 3D phase field simulations on electrical treeing successfully forecast the electrical tree structures in pure epoxy and nanocomposites with new insights into the dielectric breakdown. This research addresses a crucial need in the numerical modeling of nanocomposite interfaces and their role in dielectric breakdown analysis, providing a valuable tool for the design of next-generation dielectric materials with improved energy storage capabilities.聚合物纳米复合材料的发展已成为实现高密度储能的一种有前途的方法。然而，直接表征基质和纳米颗粒之间的界面是提高性能的关键因素，这一挑战导致了有效建模方法的缺乏。在这项工作中，我们提出了一种新的界面建模方法，定量描述介电性质在界面上的连续转变，捕捉实验观察到的非均匀性。建立了一个决定系数超过0.999的精细调谐多项式混沌神经网络（PCNN）来解释模型参数与纳米复合材料介电常数之间的关系。采用所提出的界面模型的有限元模型在预测各种纳米复合材料系统的介电常数方面具有更高的准确性，并且具有对界面的物理洞察力。在界面模型的基础上，建立了相场模型来研究纳米复合材料中的介电击穿机制，强调了界面排斥击穿路径的能力。电树的三维相场模拟成功地预测了纯环氧树脂和纳米复合材料中的电树结构，为研究介电击穿提供了新的见解。本研究解决了纳米复合材料界面数值模拟及其在介电击穿分析中的关键需求，为设计具有改进储能能力的下一代介电材料提供了有价值的工具。DLP-based Additive Manufacturing of Hollow 3D Structures with Surface Activated Silicone Carbide-polymer CompositeAnasheh Khecho, M.M Towfiqur Rahman, Deepshika Reddy, Ahmed El-Ghannam, Erina Baynojir Joyeedoi:10.1016/j.compositesb.2025.112236基于dlp的表面活化碳化硅-聚合物复合材料空心三维结构的增材制造Additive manufacturing (AM) has revolutionized the fabrication of ceramic (Silicon Carbide, SiC)-polymer composites, offering enhanced material properties such as lighter weight, toughness, and thermal characteristics. Despite these advancements, a significant knowledge gap persists in effectively processing SiC with high solid loading to achieve desired mechanical and thermal behaviors. This paper addresses this gap by exploring material properties and addressing two major challenges: adequate rheology and avoiding printing failure for excessive separation force in photopolymerization-based AM processes. In this study, high solid loading SiC-polymer composite resins were successfully developed for direct light projection (DLP)-based AM. Resin processability was determined by rheological properties and curing parameters, with resin preparation involving orthogonal optimization of compositions to achieve suitable viscosity, stability, and homogeneity. Experimental determination of photocuring parameters (curing time and critical exposure) was also conducted. Viscosity was found to increase with particle size reduction, with higher solid loading resulting in exponential viscosity growth. Additionally, a 3D part with a hollow structure and fine resolution, featuring densified uniform particle distribution, was successfully fabricated. This study further developed a DLP prototype and SiC-polymer composites with varied particle size and loading concentrations were additively manufactured. The influence of SiC particles on compressive strength and thermal conductivity of the 3D printed samples was investigated. Results revealed a proportional relationship between compressive strength, thermal conductivity, and solid loading, demonstrating significant improvements compared to pure polymer matrices. This study provides a material basis for polymerization-based 3D printing of porous structures, demonstrating the potential for advanced applications in various industries.增材制造（AM）彻底改变了陶瓷（碳化硅，SiC）聚合物复合材料的制造，提供了更轻的重量，韧性和热特性等增强的材料性能。尽管取得了这些进步，但在有效加工具有高固体载荷的SiC以实现所需的机械和热行为方面，仍然存在显着的知识差距。本文通过探索材料特性和解决两个主要挑战来解决这一差距：在基于光聚合的增材制造工艺中，充分的流变性和避免过度分离力导致的打印失败。本研究成功开发了高固载sic -聚合物复合树脂，用于直接光投射（DLP） AM。树脂的可加工性由流变性能和固化参数决定，树脂的制备包括正交优化，以达到合适的粘度、稳定性和均匀性。实验确定了光固化参数（固化时间和临界曝光）。粘度随粒径的减小而增加，较高的固体负荷导致粘度指数增长。此外，还成功制备了具有致密均匀颗粒分布、中空结构和精细分辨率的三维零件。本研究进一步开发了DLP原型，并增材制造了不同粒径和负载浓度的sic -聚合物复合材料。研究了SiC颗粒对3D打印样品抗压强度和导热系数的影响。结果揭示了抗压强度、导热系数和固体载荷之间的正比关系，与纯聚合物基质相比有显著改善。该研究为基于聚合的多孔结构3D打印提供了物质基础，展示了在各个行业的先进应用潜力。来源：复合材料力学仿真Composites FEM
