Leungdoi:10.1016/j.compstruct.2024.118302海水海砂工程水泥基复合材料（SS-ECC）与玻璃纤维增强聚合物（GFRP）棒材的微观结构、力学性能和相互作用机理With increasing demand for sustainable and long-lasting materials, seawater sea-sand engineered cementitious composite (SS-ECC) has emerged as a promising alternative to conventional concrete in near-ocean construction projects. Glass fiber reinforced polymer (GFRP) bar with excellent corrosion resistance is an ideal choice for these applications. This study evaluated the bond performance of GFRP bars embedded in normal-strength ECC with polyvinyl alcohol (PVA) fibers and high-strength ECC with polyethylene (PE) fibers through pull-out tests. Additionally, tests were conducted on GFRP bars in pristine ECC made with freshwater and river sand for comparison. Further investigation explored the structural properties and uncovered load transfer mechanisms. Results indicate that saline content facilitates early cement hydration of normal-strength ECC, resulting in finer pore structure (10.5% lower porosity and 12.5% lower sorptivity), slightly enhanced compressive performance (1.2% higher compressive strength and 8.3% higher elastic modulus), denser microstructure at GFRP-ECC interface (13.7% lower porous transition zone thickness, 19.2% narrower transition zone and 19.7% higher Ca/Si ratio), superior bond performance (28.3% higher bonding strength and 22.6% higher fracture energy). Conversely, saline content imposes a limited impact on the mechanical properties of high-strength ECC, primarily attributed to the ultra-fine microstructure and early strength characteristics exhibited by the SF-based cementitious binder随着对可持续和长效材料的需求日益增长，海水海砂工程水泥基复合材料（SS-ECC）已成为近海建设项目中替代传统混凝土的一种前景广阔的材料。具有优异耐腐蚀性能的玻璃纤维增强聚合物（GFRP）棒材是这些应用的理想选择。本研究通过拉出试验，评估了嵌入普通强度 ECC（含聚乙烯醇（PVA）纤维）和高强度 ECC（含聚乙烯（PE）纤维）中的玻璃纤维增强聚合物棒材的粘结性能。此外，还对使用淡水和河沙制成的原始 ECC 中的 GFRP 钢筋进行了测试，以进行比较。进一步的研究探讨了结构特性并揭示了荷载传递机制。结果表明，含盐量可促进正常强度 ECC 的早期水泥水化，使孔隙结构更细（孔隙率降低 10.5%，吸水率降低 12.5%），抗压性能略有提高（抗压强度提高 1.2%，弹性模量提高 8.3% ），GFRP-ECC 界面的微观结构更致密（多孔过渡区厚度降低 13.7%，过渡区变窄 19.2%，Ca/Si 比率提高 19.7%），粘结性能更优异（粘结强度提高 28.3%，断裂能提高 22.6%）。相反，盐分含量对高强度 ECC 的机械性能影响有限，这主要归因于 SF 基水泥基粘结剂所表现出的超细微观结构和早期强度特性。Low-velocity impact analysis and multi-objective optimization of hybrid carbon/basalt fibre reinforced composite laminateWenchao Xu, Jing Chen, Xiaofan Cui, Dengfeng Wang, Yongfeng Pudoi:10.1016/j.compstruct.2024.118305碳/钴混合纤维增强复合材料层压板的低速冲击分析和多目标优化Three-dimensional in-plane progressive damage model was developed for carbon/basalt fibre interlayer hybrid composites in this study, and cohesive element model was employed to simulate interlaminar damage. Numerical simulation of low-velocity progressive impact damage of hybrid composite laminate was carried out, and its accuracy was verified by physical impact test, with the maximum error of the maximum contact force, maximum displacement and energy absorption not exceeding 7% and the maximum error in damage area size within 5%. The effects of lay-up structure and angle on the impact properties of hybrid laminate were investigated through simulation. Finally, real number coding strategy was proposed for the parametric representation of the lay-up material and angle of each layer. Multi-objective optimization of hybrid laminate based on Kriging surrogate model and hybrid algorithm composed of elitist non-dominated sorting genetic algorithm and multi-objective particle swarm algorithm was conducted. The optimal trade-off solution was selected from the Pareto solutions using grey relational analysis coupled with principal component analysis method. The coefficient of variance between peak force and maximum displacement of the optimized laminate was 49.3%, 44.9% and 31.4% lower than those of the pure CFRP laminate, pure BFRP laminate, and hybrid laminate before optimization, respectively, indicating that the balance degree of impact displacement and force has been substantially improved. The progressive impact damage simulation and parametric optimization design methodology proposed in this study provide useful guidance for the design of hybrid composite laminate.本研究针对碳/盐纤维层间混合复合材料建立了三维平面内渐进损伤模型，并采用内聚元素模型模拟层间损伤。对混合复合材料层压板的低速渐进式冲击损伤进行了数值模拟，并通过物理冲击试验验证了其准确性，最大接触力、最大位移和能量吸收的最大误差不超过 7%，损伤面积大小的最大误差在 5%以内。通过仿真研究了铺层结构和角度对混合层压板冲击性能的影响。最后，提出了实数编码策略，用于参数化表示各层的铺层材料和角度。基于 Kriging 代理模型以及由精英非支配排序遗传算法和多目标粒子群算法组成的混合算法，对混合层压板进行了多目标优化。利用灰色关系分析法和主成分分析法从帕累托解中选出了最佳权衡解。与优化前的纯 CFRP 层压板、纯 BFRP 层压板和混合层压板相比，优化后的层压板峰值力和最大位移之间的方差系数分别降低了 49.3%、44.9% 和 31.4%，表明冲击位移和力的平衡度得到了大幅提高。本研究提出的渐进式冲击损伤模拟和参数优化设计方法为混合复合材料层压板的设计提供了有益的指导。Shear response and deformation mechanism of boron nitride nanosheets reinforced aluminum matrix compositesKezhong Xu, Jinming Li, Yuqi Zhou, Yuhan Gao, Xin Lei, Fulong Zhudoi:10.1016/j.compstruct.2024.118298氮化硼纳米片增强铝基复合材料的剪切响应和变形机理Atomistic simulations are performed to study the shear response and deformation mechanism of boron nitride nanosheet (BNNS) reinforced aluminum (Al) matrix composites. In this work, stacked BNNS/Al composites and dispersed BNNS/Al composites with various BNNS layers are constructed, respectively. Our computations show that the wrinkle deformation of BNNS under shear loading does not lead to the loss of load-bearing capacity. However, the yield of the Al matrix causes it to lose load-bearing capacity. The occurrence of wrinkles in BNNS aggravates the plastic failure of the Al matrix. High BNNS volume fraction increases the shear modulus and flow stress of stacked BNNS/Al composites but decreases the shear strength. Compared with stacked BNNS/Al composites, the mechanical properties of dispersed BNNS/Al composites are remarkably improved with the increase of BNNS interface in both elastic and plastic stages. In addition, the BNNS interface is able to obstruct the propagation of dislocations and stacking faults in the Al matrix. These findings may deepen our understanding of the mechanical properties and deformation mechanisms of BNNS/Al composites.为了研究氮化硼纳米片（BNNS）增强铝（Al）基复合材料的剪切响应和变形机制，我们进行了原子模拟。在这项工作中，分别构建了叠层 BNNS/Al 复合材料和具有不同 BNNS 层的分散 BNNS/Al 复合材料。我们的计算表明，BNNS 在剪切荷载下的皱缩变形不会导致承载能力的丧失。然而，铝基体的屈服会导致其失去承载能力。BNNS 出现皱纹会加剧铝基体的塑性破坏。高 BNNS 体积分数会增加叠层 BNNS/Al 复合材料的剪切模量和流动应力，但会降低剪切强度。与叠层 BNNS/Al 复合材料相比，随着 BNNS 界面的增加，分散 BNNS/Al 复合材料在弹性和塑性阶段的力学性能都得到了显著改善。此外，BNNS 界面还能阻碍位错和堆积断层在铝基体中的传播。这些发现可加深我们对 BNNS/Al 复合材料机械性能和变形机制的理解。Experimental and numerical investigation of an additively manufactured sandwich composite bridge deck utilizing gyroid building blocksLucija Stepinac, Josip Galić, Anastasios P. Vassilopoulosdoi:10.1016/j.compstruct.2024.118304利用陀螺构件对添加式制造的三明治复合材料桥面进行实验和数值研究This work investigates the integration of Additive Manufacturing (AM) techniques with cellular metamaterials integrated into composite sandwich beam systems. The study proposes an approach that combines composite materials for the face sheets with cellular structures using a Triply Periodic Minimal Surface (TPMS) Gyroid structure for the core to achieve maximum lightweight and load-bearing capabilities. The experimental and numerical campaigns were utilized for the material testing of 3D printing polymeric material reinforced with chopped carbon fibre (CF). To validate the composite sandwich structure, three bending experiments were conducted: (a) bending of the “core only” was performed to calibrate the material for the given print parameters; (b) bending of the “sandwich beam” composite with a periodic and homogenous Gyroid core bonded with glass fibre reinforced polymer (GFRP) face sheets; (c) the “arch beam” composite with the change in outer cross-section dimension with the same periodic and homogenous Gyroid core. The FEM analysis was combined with Digital Image Correlation (DIC) results to determine the bending stiffness of the sandwich beams and to detect the failure modes. It was discovered that integrating 3D printing into load-bearing structures through the composite “sandwich beam” system resulted in seven times increase in load-bearing capacity and four times increase in stiffness compared to results obtained with the “core only” structure.这项研究探讨了将增材制造（AM）技术与蜂窝超材料集成到复合材料夹层梁系统中。研究提出了一种方法，将复合材料面片与蜂窝结构相结合，使用三周期最小面（TPMS）Gyroid 结构作为核心，以实现最大的轻质和承载能力。实验和数值计算活动用于对用切碎碳纤维（CF）增强的 3D 打印聚合物材料进行材料测试。为验证复合夹层结构，进行了三次弯曲实验：（a）对 "仅芯材 "进行弯曲，以校准给定打印参数下的材料；（b）对 "夹层梁 "复合材料进行弯曲，该复合材料具有周期性和均质的陀螺型芯材，并与玻璃纤维增强聚合物（GFRP）面片粘合；（c）对 "拱形梁 "复合材料进行弯曲，该复合材料具有相同的周期性和均质陀螺型芯材，并改变了外截面尺寸。有限元分析与数字图像关联（DIC）结果相结合，确定了夹层梁的弯曲刚度，并检测了破坏模式。研究发现，通过复合 "夹心梁 "系统将 3D 打印技术整合到承重结构中，与 "仅核心 "结构相比，承重能力提高了七倍，刚度提高了四倍。Composites Part A: Applied Science and ManufacturingA printable shear stiffening composite with enhanced fracture toughness and impact resistance for intelligent wearable applicationsChunyu Zhao, Yingfu Wang, Congcong Lou, Yu Cai, Xinglong Gongdoi:10.1016/j.compositesa.2024.108319 一种可打印的剪切加固复合材料，具有更高的断裂韧性和抗冲击性，适用于智能可穿戴应用The continuous advancement in shear stiffening materials has sparked innovation in the field of flexible wearable devices. However, conventional preparation techniques for these materials have drawbacks such as limited toughness and lack of structural design. Herein, we propose a convenient fabrication method for shear stiffening elastomer (SSE) composite using a direct-ink-writing (DIW) assisted manufacturing technique. The influence of SSE structural design strategy on the mechanical behavior of composite is comprehensively investigated using crack propagation and dynamic impact experiments. Benefiting from the mechanically complementary effect of two-phase materials, coupled with robust interfacial adhesion, the composite with a densely arranged rectangular SSE structure exhibits high fracture toughness (2776.10 J⋅m−2) and impact force dissipation (61.78 %). Further, by integrating the printable composite with deep learning-based wireless sensing modules, a wearable elbow pad with attractive man–machine interaction is developed, which verifies the broad application prospect of this composite in intelligent protection.剪切加固材料的不断进步引发了柔性可穿戴设备领域的创新。然而，这些材料的传统制备技术存在韧性有限、缺乏结构设计等缺点。在此，我们提出了一种采用直接墨水写入（DIW）辅助制造技术的剪切加固弹性体（SSE）复合材料的便捷制造方法。利用裂纹扩展和动态冲击实验全面研究了 SSE 结构设计策略对复合材料力学行为的影响。得益于两相材料的机械互补效应以及强大的界面粘附力，密集排列的矩形 SSE 结构复合材料表现出较高的断裂韧性（2776.10 J-m-2）和冲击力耗散（61.78%）。此外，通过将可打印复合材料与基于深度学习的无线传感模块相结合，开发出了一种具有人机交互吸引力的可穿戴肘垫，验证了该复合材料在智能防护领域的广阔应用前景。Discontinuous interleaving strategies for toughening, damage sensing and repair in multifunctional carbon fibre/epoxy compositesThomas D.S. Thorn, Yushen Wang, Hongxu Guo, Lichang Lu, Yi Liu, Emiliano Bilotti, Dimitrios G. Papageorgiou, Han Zhangdoi:10.1016/j.compositesa.2024.108320 用于多功能碳纤维/环氧树脂复合材料增韧、损伤传感和修复的非连续交织策略Thermoplastic interleaving is a well-established approach to toughen carbon fibre thermoset laminates, studied over the past five decades. Recently, it has been revisited to create functional smart composites with damage sensing and repair capabilities with a renewed focus on the sustainability and longevity of components. However, the introduction of thermoplastic films within the interlaminar region often lowers fibre volume fraction and performance at elevated temperature, while the addition of impermeable continuous films during manufacture may also limit compatible fabrication methods. Moreover, the incorporation of dielectric thermoplastic films inevitably reduces through-thickness electrical conductivity and prevents accurate damage sensing of delamination in carbon fibre laminates. In this study, strategies of using discontinuous interleaving to improve both fracture toughness and thermomechanical properties of carbon fibre epoxy laminates, with the ability to monitor delamination damage and restore mechanical properties after a short healing step have been explored. Both the interleaving design and the physical properties of the thermoplastic were assessed, which has not been addressed previously. Interleaving high molecular weight thermoplastic with decreasing interleaf width and distance between interleaf zones results in increased fracture toughness (+347 %), by creating a superior toughened interlaminar zone, forcing a migration of delamination into the intralaminar region. A maximum repair efficiency of 77 % was achieved when using a lower molecular weight of thermoplastic; however, the lack of thermoplastic over the entire fracture surface area affects the repairing performance universally. Damage sensing and thermomechanical properties were significantly improved compared to continuous interleaving, demonstrating that discontinuous thermoplastic interleaving strategies offer a favourable combination of toughening, thermal performance and accurate damage sensing for multifunctional high-performance composites.热塑性交错材料是一种成熟的碳纤维热固性层压材料增韧方法，在过去的五十年中得到了广泛的研究。最近，随着人们对部件可持续性和使用寿命的重新关注，这种方法被重新用于制造具有损伤传感和修复能力的功能性智能复合材料。然而，在层间区域引入热塑性薄膜往往会降低纤维体积分数和高温下的性能，而在制造过程中添加不透气的连续薄膜也可能会限制兼容的制造方法。此外，加入电介质热塑性薄膜不可避免地会降低厚度导电性，并妨碍对碳纤维层压板分层损伤的准确检测。本研究探讨了利用不连续交错技术提高碳纤维环氧树脂层压板的断裂韧性和热机械性能的策略，这种技术能够监测分层损伤，并在短时间愈合后恢复机械性能。对交错设计和热塑性塑料的物理性能都进行了评估，这在以前从未涉及过。交织高分子量热塑性塑料，减小层间宽度和层间间距，可提高断裂韧度（+347%），因为这样可形成一个优异的增韧层间区，迫使分层迁移到层内区域。使用分子量较低的热塑性塑料时，修复效率最高可达 77%；然而，整个断裂表面区域缺乏热塑性塑料会普遍影响修复性能。与连续交错法相比，损伤传感和热力学性能有了明显改善，这表明非连续热塑性交错法可为多功能高性能复合材料提供增韧、热性能和精确损伤传感的有利组合。Composites Part B: EngineeringMOF-derived metal oxide (Cu, Ni, Zn) gas sensors with excellent selectivity towards H2S, CO and H2 gasesCarmen Montoro, Jin-Young Kim, Ali Mirzaei, Jae-Hyoung Lee, Syreina Sayegh, Elissa Makhoul, Igor Iatsunskyi, Emerson Coy, Mikhael Bechelany, Hyoun Woo Kim, Sang Sub Kimdoi:10.1016/j.compositesb.2024.111637 MOF 衍生的金属氧化物（铜、镍、锌）气体传感器对 H2S、CO 和 H2 气体具有极佳的选择性Metal-organic framework (MOF)-derived metal oxides blend the sensing properties of metal oxides with MOF porosity, enhancing gas sensing capabilities. In this study, M-MOFs (M = Cu, Ni and Zn) were synthesized and then calcined at different temperatures to obtain their corresponding metal oxides (CuO, NiO and ZnO). The synthesis method incorporated novel approaches to enhance sensor performance, such as optimizing calcination temperatures for improved selectivity. Structural and morphological analyses confirmed the high surface area and porosity of the metal oxide materials, facilitating efficient gas adsorption and promoting enhanced sensor response. Gas sensing studies revealed significantly enhanced performance of MOF-derived metal oxides over M-MOFs, strongly influenced by calcination temperature. Moreover, CuO, NiO and ZnO MOF-derived metal oxides showed improved selectivity towards H2S, CO and H2 gases, respectively. This study demonstrates that tuning MOF and calcination parameters can tailor sensor selectivity effectively.金属有机框架（MOF）衍生的金属氧化物融合了金属氧化物的传感特性和 MOF 的多孔性，从而增强了气体传感能力。本研究合成了 M-MOF（M = Cu、Ni 和 Zn），然后在不同温度下煅烧以获得相应的金属氧化物（CuO、NiO 和 ZnO）。合成方法采用了新的方法来提高传感器的性能，如优化煅烧温度以提高选择性。结构和形态分析证实了金属氧化物材料的高比表面积和高孔隙率，有利于有效吸附气体并增强传感器响应。气体传感研究表明，MOF 衍生金属氧化物的性能明显优于 M-MOF，这与煅烧温度有很大关系。此外，CuO、NiO 和 ZnO MOF 衍生金属氧化物对 H2S、CO 和 H2 气体的选择性分别有所提高。这项研究表明，调整 MOF 和煅烧参数可以有效地定制传感器的选择性。来源：复合材料力学仿真Composites FEM
