Laureano, J.L. Mantaridoi:10.1016/j.compstruct.2025.120021基于数据驱动的人工智能和分层可变运动学模型的石墨烯纳米片增强夹层板的振动分析This study investigates the vibration response of sandwich panels with auxetic lattice cores and functionally graded graphene platelet reinforced composite (FG-GPLRC) face sheets using Equivalent Single Layer (ESL), Layerwise (LW), and variable-kinematic models formulated within the robust unified formulation. The enhanced Tornabene homogenization model and Halpin-Tsai micromechanics model are employed to compute the effective properties of the auxetic core and FG-GPLRC face sheets, respectively. The dynamic governing equations, derived using the Principle of Virtual Displacements (PVD), are solved in strong form via the Boundary-Continuous Method (BCM). Several cases with increasing complexity are considered. A unique case, previously unexplored in the shell literature, is introduced, offering a new benchmark for future comparisons. The results reveal that the hybrid ESL/LW capabilities of the proposed variable-kinematic model provide highly accurate and efficient a nalytical solutions for these complex sandwich structures, offering 87% reduction in the computational cost against their LW counterpart. The effects of GPL reinforcements in the face sheets and the auxetic response are investigated through parametric studies using an efficient surrogate model based on Artificial Neural Networks (ANNs). This model was trained on a synthetic dataset, generated by the most accurate an alytical model, where geometric dimensions, auxetic properties, and GPL parameters were used as input features.本研究使用等效单层（ESL）、分层（LW）和可变运动模型，在鲁棒统一公式中研究了具有缺陷晶格芯和功能梯度石墨烯血小板增强复合材料（FG-GPLRC）面板的夹层板的振动响应。采用增强的Tornabene均质模型和Halpin-Tsai细观力学模型分别计算了增厚芯和FG-GPLRC面片的有效性能。利用虚位移原理（PVD）推导出的动力学控制方程，通过边界连续法（BCM）以强形式进行求解。考虑了几种日益复杂的情况。介绍了shell文献中以前未探索的一个独特案例，为将来的比较提供了新的基准。结果表明，所提出的可变运动学模型的混合ESL/LW能力为这些复杂的夹层结构提供了高精度和高效的分析解决方案，与LW模型相比，计算成本降低了87%。采用基于人工神经网络（ann）的高效代理模型，通过参数化研究研究了GPL增强对面片的影响和辅助反应。该模型是在一个合成数据集上进行训练的，该数据集是由最精确的分析模型生成的，其中几何尺寸、auxetic属性和GPL参数用作输入特征。Composites Part A: Applied Science and ManufacturingA model for gap formation between dry preforms and curved tool surfaces in closed-mould composites manufacturing processesMikhail Y. Matveev, Andreas Endruweitdoi:10.1016/j.compositesa.2025.109548闭模复合材料制造过程中干预制件与弯曲刀具表面间隙形成的模型The formation of a gap between the dry reinforcement and the tool surface at a bend, i.e. a geometrical feature with single curvature, in a tool for closed-mould manufacturing processes is caused by tensile forces in the reinforcement. The gap shape was ana lysed based on the mechanical model of an arched beam supported by an elastic foundation. The compaction stiffness of the reinforcement was derived from linearisation of the power-law approximating the reinforcement compression response. Fifth-order differential equations were derived and solved with the appropriate boundary conditions to find expressions for the local gap height. Applying a minimum-energy principle, the gap was found to typically extend into the flat sections of the geometry on both sides of the bend. Its size increases with increasing bend angle and applied force. It decreases with increasing bend radius, cavity height, level of pre-compaction, and stiffness of the reinforcement in compaction and in bending. If the gap height is expressed as a function of the fibre volume fraction, the correlation between the gap size and the fibre volume fraction was found to be negative if the tensile force is constant, and positive if the force increases with increasing fibre volume fraction. The solutions derived here allow the geometry of the gap and the bent preform to be described in more detail than in previous studies, which allows further an alysis of the manufacturing process, e.g. predicting the effect of racetracking in the formed gap during a Resin Transfer Moulding process.在封闭模具制造过程中，在弯曲处的干燥钢筋和刀具表面之间形成间隙，即具有单一曲率的几何特征，是由钢筋中的拉伸力引起的。基于弹性基础支撑拱梁的力学模型，对其间隙形状进行了分析。钢筋的压实刚度来源于近似钢筋压缩响应的幂律的线性化。推导了五阶微分方程，并在适当的边界条件下进行了求解，得到了局部间隙高度的表达式。应用最小能量原理，发现间隙通常延伸到弯曲两侧几何形状的平坦部分。其尺寸随弯曲角度和受力的增大而增大。它随弯曲半径、空腔高度、预压实水平和钢筋压实和弯曲刚度的增加而减小。如果将间隙高度表示为纤维体积分数的函数，则当拉伸力恒定时，间隙大小与纤维体积分数之间的相关性为负，当拉伸力随纤维体积分数的增加而增加时，间隙大小与纤维体积分数之间的相关性为正。这里导出的解决方案允许比以前的研究更详细地描述间隙和弯曲预制体的几何形状，从而可以进一步分析制造过程，例如预测在树脂转移成型过程中形成的间隙中的赛道跟踪效果。Ferromagnetic amorphous Microwire based Meta-Composite absorber for Multi-Field modulation and extreme environment applicationsJing Yang, Changfeng Li, Jiaxin Liu, Xiong Lv, Yunlong Li, Yaqian Yang, Tangfeng Feng, Yunfei Wang, Baihong Chi, Faxiang Qindoi:10.1016/j.compositesa.2025.109549 多场调制和极端环境应用的铁磁非晶微丝基元复合材料吸收体Modern electromagnetic protection and radar stealth technologies require microwave-absorbing materials that exhibit high integration, robust environmental adaptability, and tunability. However, current research focuses on individual properties, creating a significant gap in developing high-performance stealth structural components with integrated multifunctionality. To bridge this gap, we propose a novel metacomposite incorporating ferromagnetic amorphous microwires, resistive square-loops, and glass fiber-reinforced epoxy. This metacomposite demonstrates excellent stealth performance, mechanical strength, thermal resistance, and field-induced tunability. Fabricated via vacuum-assisted resin transfer molding (VARTM), the optimized metacomposite achieves over 60 % absorption across the entire X-band and more than 90 % within 9.7–11.9 GHz. It also exhibits great tensile strength (487.5 MPa in axial direction), impact resistance (energy dissipation value of 9 J), and thermal stability (glass transition temperature is 163.41 °C). Furthermore, under external magnetic and thermal fields, the absorption peak achieves a 2.31 GHz blue shift and a 0.25 GHz red shift, respectively. In future research, arbitrarily shaped structural components can also be fabricated via the VARTM process, overcoming the formability limitations of conventional stealth metamaterials. By combining broadband absorption, multi-field tunability, mechanical robustness, and thermal adaptability, the developed metacomposite shows promising potential for applications in radar stealth and electromagnetic protection, especially under extreme operating conditions.现代电磁保护和雷达隐身技术需要具有高集成度、强环境适应性和可调性的微波吸收材料。然而，目前的研究主要集中在单个性能上，在开发具有集成多功能的高性能隐身结构部件方面存在很大差距。为了弥补这一差距，我们提出了一种新型的超复合材料，包括铁磁非晶微线，电阻方环和玻璃纤维增强环氧树脂。这种超复合材料具有优异的隐身性能、机械强度、耐热性和场致可调性。通过真空辅助树脂传递成型（VARTM）制造，优化后的超复合材料在整个x波段的吸收率超过60% %，在9.7-11.9 GHz范围内的吸收率超过90% %。具有良好的抗拉强度（轴向487.5 MPa）、抗冲击性能（能量耗散值9 J）和热稳定性（玻璃化转变温度163.41 ℃）。此外，在外加磁场和热场作用下，吸收峰分别实现了2.31 GHz的蓝移和0.25 GHz的红移。在未来的研究中，还可以通过VARTM工艺制造任意形状的结构部件，克服传统隐身超材料的成形性限制。通过结合宽带吸收、多场可调性、机械稳健性和热适应性，所开发的超复合材料在雷达隐身和电磁保护方面具有广阔的应用前景，特别是在极端工作条件下。Composites Part B: EngineeringLaser-engineered interfaces for fiber–metal laminates: Linking surface morphology, chemistry, and adhesion performanceMuhammad Adeel Khan, Aiman Mohd Halil, Uzair Naeem, Mohd Shukur Zainol Abidin, Muhammad Hafiz Hassan, Aslina Anjang Ab Rahmandoi:10.1016/j.composites b.2025.113368 激光工程界面的纤维-金属层压板：连接表面形态，化学，和粘附性能Fiber–metal laminates are increasingly employed in aerospace, automotive, and marine structures due to the modern scientific pursuit of energy efficiency and structural performance. Adhesive bonding offers a lightweight alternative to mechanical fastening; however, achieving reliable bonding between dissimilar materials such as metals and composites remains challenging. This study explores untextured, single- and dual laser surface texturing (LST) to enhance interfacial adhesion in Al6061/E-glass composite laminate. A nanosecond (1064 nm) pulsed fiber laser was used to fabricate square and grid textures with two hatch distance: 0.1 mm, 0.2 mm on Al6061, while corresponding patterns were produced on E-glass composites at reduced power to prevent matrix degradation and fiber damage. The untextured configuration consisted of as-received Al6061 and composite laminates with peel-ply and Teflon imprints. Surface morphology was an alyzed using SEM, optical, and confocal microscopy, and quantified by areal parameters (Sa, Sq, Ssk, Sku, Sdr). Reduced hatch spacing and grid patterns exhibited enhanced surface morphology, bonding area, and balanced peak–valley distributions. EDX confirmed oxygen enrichment on Al6061, while FTIR revealed specific functional groups on textured composites. Wettability tests indicated complete wetting on Al6061 and higher contact angles on composites due to roughness-induced Cassie–Baxter states. Single-lap shear tests demonstrated significant strength improvement over peel-ply and Teflon baselines. Dual texturing showed marginal gains for certain conditions, whereas single-sided texturing at 0.2 mm achieved the highest performance. Overall, this study establishes a process–structure–property relation in LST, enabling predictive optimization of adhesion in hybrid joints for advanced lightweight structures.由于现代科学对能源效率和结构性能的追求，金属纤维层压板越来越多地应用于航空航天、汽车和海洋结构中。粘合剂粘合提供了一种轻便的机械紧固替代方案；然而，在金属和复合材料等不同材料之间实现可靠的粘合仍然具有挑战性。本研究探讨了无纹理、单和双激光表面纹理（LST）来增强Al6061/ e-玻璃复合层压板的界面附着力。利用纳秒（1064 nm）脉冲光纤激光器在Al6061上制备了两种孔径分别为0.1 mm和0.2 mm的方形和网格纹理，并在E-glass复合材料上以低功率制备了相应的纹理，以防止基体降解和纤维损伤。无纹理结构由接收的Al6061和具有剥离层合和聚四氟乙烯压痕的复合层压板组成。使用扫描电镜、光学显微镜和共聚焦显微镜分析表面形貌，并通过面积参数（Sa、Sq、Ssk、Sku、Sdr）进行量化。减小的舱口间距和栅格模式表现出增强的表面形貌、键合面积和平衡的峰谷分布。EDX证实了Al6061上的氧富集，而FTIR显示了织构复合材料上的特定官能团。润湿性测试表明，由于粗糙度引起的Cassie-Baxter状态，Al6061上的完全润湿和复合材料上的更高接触角。单圈剪切试验表明，与剥离层合和聚四氟乙烯基线相比，强度有显著提高。双面纹理在某些条件下表现出边际增益，而单面纹理在0.2 mm处表现出最高的性能。总体而言，本研究在LST中建立了工艺-结构-性能关系，实现了先进轻量化结构混合接头粘附性的预测优化。Composites Science and TechnologyStrategic structural design of polyimide dielectrics toward superior high-temperature energy storage performanceJing Ye, Ao Xu, Zhijia Wang, Hang Luo, Xiwen Yang, Sheng Chendoi:10.1016/j.compscitech.2025.111514 聚酰亚胺电介质的战略性结构设计，以获得优异的高温储能性能All-aromatic polyimide dielectric films will seriously lose their energy storage performance at high temperatures because of high conductive loss caused by the conjugation effect of benzene rings in the backbone and charge transfer effect, especially commercial Kapton film. In order to maintain the low leakage current and energy storage stability of polyimide under high temperature and electric field, a synergistic strategy is employed to synthesize Kapton-based cross-linked dielectric films, involving polyhedral oligomeric silsesquioxane (POSS) cross-linked structure and a partial aliphatic structure. The results show that the energy storage performance of cross-linked ternary polyimides is significantly enhanced at room temperature and high temperature due to the construction of a “peak-shaped barrier” that effectively suppresses charge injection and transport. The discharge energy densities at room temperature and 150 °C are 8.01 J/cm3 and 5.04 J/cm3, respectively, which are much higher than those of pure Kapton. This study provides a valuable strategy and insights for the development of polyimide dielectrics with high capacitive properties over a wide temperature range.全芳香族聚酰亚胺介电膜在高温下由于苯环的共轭效应和电荷转移效应造成的高导电性损失会严重丧失其储能性能，尤其是商用Kapton膜。为了保持聚酰亚胺在高温和电场下的低漏电流和储能稳定性，采用协同策略合成了kapton基交联介质薄膜，包括多面体低聚硅氧烷（POSS）交联结构和部分脂肪族结构。结果表明，交联三元聚酰亚胺在室温和高温下的储能性能都得到了显著提高，这是由于构建了一个“峰状势垒”，有效地抑制了电荷注入和输运。室温和150℃下的放电能量密度分别为8.01 J/cm3和5.04 J/cm3，远高于纯卡普顿的放电能量密度。该研究为开发具有宽温度范围内高电容性能的聚酰亚胺介电材料提供了有价值的策略和见解。来源：复合材料力学仿真Composites FEM
