Abstract ：
A bistable composite cylindrical structure is a thin-walled shell, stable in its extended and coiled configurations, that offers large shape-morphing capabilities without structural damage. It has been successfully applied to deployable structures and launched into orbit. Smart-morphing designs provide new freedom and flexibility for space-deployable mechanics, reducing structural weight and complexity. Here, we present a novel magnetically activated bistable composite cylindrical structure, where the fundamentals of the critical magnetic driving boundaries are revealed for the first time to develop a reversed smart-morphing design principle. This is achieved by employing a magnetically responsive area within a bistable composite, where the NdFeB particles are co-cured directly with the carbon layups to ensure good bonding. Theoretical analysis of the magnetic driving principle was developed to reveal the interacting mechanics of a bistable structure subjected to magnetic actuation. The magnetic field distribution was characterized through experiments; a series of magnetic-responsive bistable composite cylindrical samples were produced and subjected to magnetic activation to determine the critical shape transition intensities. Their shape-changing processes were also evaluated through mechanical testing and compared to the magnetic driving mechanics. It is found that there is an optimal level of magnetic particle concentration to minimize the magnetically responsive time and input energy. The critical boundaries in terms of the current and air gap are established through theoretical analysis and verified through experimental observations. The magnetic driving mechanics are then discussed and concluded in detail. This provides a simple and effective alternative for smart actuation and morphing control of bistable composite structures, supporting their future applications in deep space exploration.

Abstract ：
A bistable composite tape-spring (CTS) structure is a thin-walled open slit tube with fibres oriented at +/- 45 degrees, which is stable at both the extended and fully coiled configurations. Owning to its positive Gaussian curvature deformation mechanics and high stowage-to-pack ratio, it has been successfully applied and launched to International Space Station and microsatellites to construct deployable solar sails. Intelligent driving designs of the CTS-based deployable structures are becoming more and more important to further reduce weight and complexities for space applications. Here, we presented novel findings on the passive thermal driving mechanics of the bistable CTS structure. This is achieved by exploring the thermal energy-induced microstructural expansion and contraction, which would change the structural curvature, and thus regulating the strain energy within the CTS. An analytical model on the strain energy evolution under thermal effects was established to predict the minimum stable shape transition paths, as well as to determine the critical boundary conditions for thermal driving. Both experiments and finite element model were then carried out to reveal underlying mechanisms. It is found that a CTS is able to be passively deployed under thermal energy, there is a minimum energy constraint to initiate the shape morphing process, and the critical boundaries are dependent on the thermal expansion of the structural material. These findings provide a novel low cost, simple and reversed smart morphing design principle of the CTS structure, enriching the theoretical analysis and deployable control of the bistable composites to benefit future deep space explorations.

Abstract ：
Metamaterials (MMs) have become increasingly prominent in terahertz flexible devices. However, bending deformation often alters the structure of the unit, which affects the response performance and stability of MMs. Here, a metal-aperture metamaterial (MA-MM) utilizing the strong coupling effect induced by two resonance modes is innovatively proposed to address the mentioned limitations. Specifically, it is found that the coupling state between multiple resonance modes remains consistent at different bending angles. Under these circumstances, the generated Rabi splitting peak presents stable response performance even under low resonance intensity caused by excessive deformation. The experimental results demonstrate that despite the amplitude of two resonant peaks decreasing significantly by 87.6%, the Q-factor of the Rabi splitting only reduced by 14.8%. Furthermore, armed with the response mode of the Rabi splitting being unaffected by plasma excitation range, the designed MA-MMs are able to maintain constant Q-factors and frequencies on curved surfaces of varying sizes. These findings exhibit the characteristics of electromagnetic response for multi-mode resonance-coupled MAMMs on different curved surfaces, presenting a novel design approach for terahertz flexible functional devices.

Abstract ：
The rapid development of aerospace technology has continuously promoted the demand for lightweight and systematic design of twisting structures, where advanced composites have drawn great expectations. A double helical structure has been developed to introduce large axial twistable capability, where thin-walled cured composite strips with a longitudinal curvature were prestressed or flattened to be employed as shape-changing units, and then assembled by using rigid spokes, pins, or webs; however, its twisting performance would be susceptible to thermal effects, and affected by the curvature variations induced by flattening and assembling of the precured curved strips. Here, we proposed a novel double helical structural design, where thin-walled curved tapes with transverse curvature were applied as the shape-changing units without prestressing. The double helical structures were produced and investigated with isotropic transverse curved tapes, orthotropic flat strips, as well as orthotropic transverse curved tapes, in order to reveal its geometric curvature effects-induced twisting mechanics. An inextensible shell model was formulated to analyse the shape-changing process, and expose the regulating mechanisms on structural stability. Experiments and finite element analysis were carried out to investigate the material and geometric curvature dependencies. It is found that the material orthotropy contributes to the bistability of the helical structure; geometric curvature promotes the stiffness and shape-changing stability of the double helix. The twisting mechanisms were then concluded in detail. These findings are expected to facilitate torsional structural design and application of deployable composite structures for aerospace engineering.

Abstract ：
Active absorption modulation is critical for advanced stealth technologies, especially given the emerging detection threat from terahertz atmospheric windows. However, due to the difficulty in balancing high absorption and tunability, the actual manufacturing of most terahertz absorbers usually neglects the integration of electrical tuning, which limits their development of dynamic wave trapping for electronic countermeasure systems. Here, a terahertz stealth metamaterial (TSM) with hierarchical ionotronic architecture is proposed to overcome the tradeoff. Large-area continuous MoS2 assemblies tightly attached poly(ionic liquid) (PIL) microarrays provide enough conditions for surface electron conduction and plasmon mode excitation. By establishing wave-electron-ion interaction pathways, the directional migration of free anions inside the PIL and the accumulation of excess charge carriers up to 100.4% at the MoS2 interfaces are promoted, thereby stimulating changes in the plasma frequency of the absorption system. Consequently, this micro-nano structural design enhances the absorption tunability and combines multiple dissipative behaviors. TSM exhibit high specific attenuation (-275 dB mm(-1)), frequency agility (21.4%), and phase switching (153.1 deg.) within terahertz atmospheric windows. Moreover, the template-assisted assembly strategy adopted has the potential to be used for the building of universal blocks operating within other frequency ranges.

Abstract ：
Bistable composite cylindrical structures have been developed over the last four decades, and show great potential for shape morphing applications, especially in aerospace. Their bistabilities are known to be induced by unsymmetric composite layups, while the governing factors on shape geometries and viscoelastic mechanics remain an enigma. Here, we investigated the intricate relationship between structural geometry and stable mechanics of a bistable unsymmetric composite cylindrical structure. A polylactic acid (PLA)-based carbon composite laminate was prepared through 3D printing, which released design freedom on structural fiber volume fraction that could be controlled by modulating hatch spacing between the composite yarns. This strategic adjustment allowed the regulation of grid density, hence the in-plane stress level, which dominates the bistable geometries. The cylindrical composite samples were produced with hatch spacing changed from 1.25 to 5 mm, corresponding to a fiber volume fraction ranged from 24.2% to 6.6%, where the structural curvature was also changed by up to 50% difference and gradually became viscoelastic dependent. It is found that the internal stress difference in thickness direction dominates the structural bistability, and there is a threshold value on the stress difference magnitude to essentially maintain the bistable configurations. These findings are expected to facilitate reversed structural design and manufacturing of the bistable cylindrical shells with tailorable stability, and promote their viscoelastic-based large shape morphing fatigue life predictions.Highlights Bistable composite cylindrical shells were produced with various grid density. A theoretical model was established to predict the time-dependent bistability. Stress difference in thickness direction dominates the structural curvature. Stress contour reveals the viscoelastic-dependent bistable mechanics.

Abstract ：
The composite segmented tools, used as the internal mandrel, are crucial in the integrated curing process of aerospace composite tanks. Their precise manufacturing demands stringent curing process requirements. Current studies lack reports on the curing simulation and process optimization of the segmented tools, making it challenging to provide effective guidance for the high-quality manufacturing of aerospace composite tanks. This study focuses on the composite segmented tools for a Phi 3.35 m liquid oxygen tank. The curing kinetics equations and thermophysical properties of T800/epoxy composites were tested and fitted. Finite element prediction models for the temperature and deformation evolution during the curing process were constructed. Based on the orthogonal experimental design, the curing parameters were optimized, and an engineering trial of the composite panel was completed. The results indicate that the heating rate has the most significant impact on the curing deformation of segmented tools, while the curing temperature has the greatest effect on curing uniformity. Under the optimized process parameters, the curing deformation of the composite panel obtained by the finite element model only has a 6.67% error compared to the experimental results, which not only validates the accuracy of the simulation models but also achieves precise manufacturing of the composite segmented tools.

Abstract ：
The integrated manufacturing of aerospace composite cryogenic tanks is crucial for enhancing payload efficiency, reducing costs, and leading the aerospace industry upgrade. Composite segmented tool, which balances internal support and mold surface, must not only meet the requirements of disassembly and demolding but also ensure sufficient stiffness without deformation under loads like winding tension and curing shrinkage during tank formation. This article addresses the challenge faced by composite tool with uniformly thick ply stacking schemes, where the weight increases significantly with the rocket body diameter, rendering functions such as disassembly and demolding unfeasible. A global-local optimization approach aimed at achieving variable-thickness ply stacking designs for composite tooling was proposed. Starting with a defined segmented tool design for the phi 3.35 m tank, models for calculating winding tension under complex service conditions and finite element models for curing shrinkage were established. Optimization of ply shapes, dimensions, and sequences using OptiStruct was conducted, which achieved a weight reduction of 34.48% while ensuring that deformations under loading met design standards. Subsequently, the engineering trials for the composite melon petal and wallboard corresponding to the phi 600 mm tank were conducted based on the optimized scheme. The maximum deformations for the two components were 0.43 mm and 0.15 mm, respectively, meeting the manufacturing requirements for engineering applications. The results provide a lightweight, high-stiffness, and detachable tool design scheme for achieving the integrated manufacturing of extra-large (phi 10 m) composite tanks.Highlights The external load was analyzed through theoretical and simulation approaches. The weight of composite tool was significantly reduced after optimization. The engineering prototypes of the segmented tools were achieved.
