“…Such materials may enhance the durability of future space structures [190]. However, it is still challenging to replace whole spacecraft parts with self-healing composite [191]. Similarly, the use of ecofriendly self-healing materials based on sustainable polymers can be a research focus for future efficient aerospace structures.…”

Self-healing polymers and nanocomposites form an important class of responsive materials. These materials have the capability to reversibly heal their damage. For aerospace applications, thermosets and thermoplastic polymers have been reinforced with nanocarbon nanoparticles for self-healing of structural damage. This review comprehends the use of self-healing nanocomposites in the aerospace sector. The self-healing behavior of the nanocomposites depends on factors such as microphase separation, matrix–nanofiller interactions and inter-diffusion of polymer–nanofiller. Moreover, self-healing can be achieved through healing agents such as nanocapsules and nanocarbon nanoparticles. The mechanism of self-healing has been found to operate via physical or chemical interactions. Self-healing nanocomposites have been used to design structural components, panels, laminates, membranes, coatings, etc., to recover the damage to space materials. Future research must emphasize the design of new high-performance self-healing polymeric nanocomposites for aerospace structures.

“…The passive safety in aviation refers to measures taken to protect passengers and crew in the event of an accident or an emergency landing, reducing the risk of injury or death. [1,2] A key issue in the passive safety for passengers is the introduction of solutions able to absorb part of the impact energy through deformation and failure mechanisms, reducing the loads transferred to passengers during a crash event or ditching. [3][4][5] A valuable method for investigating the effectiveness of a new design for a passive safety system or the improvement of an existing one is provided by anthropomorphic test devices (ATDs) available for most of the FE codes.…”

The passive safety in aircraft concerns all measures able to protect the passengers and crew in the event of an accident or emergency. In this context, an important role is played by the design adopted for components inside the passengers’ cabin, such as the seats and the interior lining. An effective approach in design of passive safety system is provided by anthropomorphic test devices. In this work, a new design of the interior lining of the fuselage wall has been introduced and its crashworthiness features have been studied through a side impact of an unbelted window‐side passenger. The new proposed interior lining is made with a hybrid sandwich‐based design with a polypropylene honeycomb core able to ensure passive safety for passengers and thermal and acoustic insulation.

“…In the past 50 years, research institutions in the United States, Japan, the European Union, China, and other countries have conducted collision tests on the fuselage and whole aircraft of various civil aircraft, based on three important indicators: collision deformation mode, acceleration response, and energy absorption characteristics. 3 Caputo and Riccio 4,5 proposed a new finite-element method to simulate aircraft fuselages using full-size composite materials. Building upon this method, Riccio et al 6,7,8 studied the impact resistance of composite fuselage sections when subjected to different impact angles with rigid ground.…”

With the increasing development of micro aerial vehicle, the impact resistance of the structure has gradually become a research hotspot. The beetle's exoskeleton not only provides important protection for its body and flexible wings but also ensures its good flight performance. Therefore, the beetle's exoskeleton has become an important research content in the field of bio-mimetic micro aerial vehicles. In this study, taking the internal structure of the beetle's exoskeleton as the research object, a kind of bio-mimetic lightweight thin-walled impact-resistant structure that can be used in the micro aerial vehicle is proposed. The energy absorption characteristics of the bio-mimetic structure under axial impact loading are calculated and analyzed by the numerical simulation method, and the important parameters such as impact angle, protective layer thickness, and wall thickness are optimized and discussed. The main results include that the filling method of the hollow column has a certain correlation with the energy absorption characteristics of the structure under different impact angles, and among the different cross-sectional shapes, the hollow column with a circular cross-sectional configuration has the best energy absorption ability. In addition, as the internal space of the structure increase exponentially, the decrease of specific energy absorption value of the bio-mimetic structure is relatively small. Finally, the wall thickness with good energy absorption characteristics is about 1.5 mm, while the preferred span length of the structure is between 90 and 120 mm.
