Special Issue Information

Dear Colleagues,

Aerospace science and technology are increasingly dedicated to the advancement of high-performance structural composite materials and the integration of smart structures through cutting-edge manufacturing processes, meticulous material characterisations, and rigorous structural evaluations. Fibre-reinforced composites are considered paramount in propelling aerospace development forward, given their compatibility with a range of matrices, including polymers (both thermoset or thermoplastic), metals, and ceramics. This multidisciplinary approach encompasses research into structural and material interactions, emphasizing specific strength, stiffness, superior mechanical properties, and multifunctionality.

Smart composite structures are enablers for mitigating adverse environmental challenges and operational complexities (such as fatigue, damage tolerance, gust alleviation, humidity, and temperature). Thus, enhancing the performance of structural composites becomes imperative for improving manoeuvrability and enabling data-driven management. The next generation of technologies, including nano-techniques, self-healing materials, and renewable composite materials, is expected to make significant contributions to the sustainability of aerospace applications.

Research and technology in advanced aerospace composite materials and smart structures encompass various other areas, including multifunctionality, digital twin technology, life cycle assessment, self-healing mechanisms, predictive maintenance, maintenance repair and overhaul, non-destructive evaluation, and structural composite mechanics and simulation.

We cordially invite you to contribute to this Special Issue on advanced aerospace composite materials and smart structures. We also welcome studies related to non-destructive inspection methods, novel material characterisation and testing, and certification efforts that support the implementation of smart composite structures.

Members of the research community are welcome to contribute their research articles, reviews, and short communications on this Special Issue, titled Advanced Aerospace Composite Materials and Smart Structures.

I would like to thank Jason Hwang (NLR, Netherlands) for his significant contribution to this Special Issue.

When spacecraft execute missions in space, their solar panels—crucial components—often need to be folded, unfolded, and adjusted at an angle. These operations can induce numerous detrimental nonlinear vibrations. This paper addresses the issues of nonlinear and thermal-coupled vibration control within the context of space-based flexible solar panel systems. Utilizing piezoelectric smart hybrid vibration control technology, this study focuses on a flexible plate augmented with an active constrained layer damping. The solar panel, under thermal field conditions, is modeled and simulated using the commercial finite element simulation software ABAQUS. The research examines variations in the modal frequencies and damping properties of the model in response to changes in the coverage location of the piezoelectric patches, their coverage rate, rotational angular velocity, and the thickness of the damping layer. Simulation results indicate that structural damping is more effective when the patches are closer to the rotation axis, the coverage area of the patches is larger, the rotational speed is lower, and the damping layer is thicker. Additionally, the effectiveness of vibration suppression is influenced by the interplay between the material shear modulus, loss factor, and specific working temperature ranges. The selection of appropriate parameters can significantly alter the system’s vibrational characteristics. This work provides necessary technical references for the analysis of thermally induced vibrations in flexible solar sails under complex space conditions. Full article

A strain isolation pad is a critical connection mechanism that enables deformation coordination between the rigid thermal insulation tile and the primary structure in the thermal protection system of a reusable hypersonic vehicle. An experimental investigation has been conducted to determine the static, loading–unloading, and high-cycle fatigue (HCF) responses of the SIP with 0.2 mm adhesive under through-thickness tension at room temperature. The contributions of the rigid thermal insulation tile and metallic substructure have not been considered so far. The results indicate that the tensile behavior of the SIP joint is highly nonlinear. The static and fatigue tensile failures both initiate from the corner close to the adhesive/SIP interface due to the stress concentration and the edge effect. The uniform breakage of the aramid fiber can be seen on the cross-section. A novel method is proposed to quantify the residual strain due to the short-time ratcheting effect of the SIP joint in the initial loading–unloading tensile response. As the number of fatigue cycles increases, the thickness of the SIP joint continues to increase until failure. An explicit expression associated with the growth of SIP joint thickness, fatigue cycle number, and peak cyclic stress is established. The turning point of the thickness growth rate with the fatigue cycle number is proposed as a new fatigue failure index for the SIP joint under tensile fatigue, and a fatigue life prediction model is developed.
