“…At present, there are still many researchers focus on developing SMPC hinges and booms, most of which are based on the EMC hinge and boom developed by CTD, but have been refined in material preparation, structural optimization and testing method to meet different engineering requirements [50,158,162]. Some new applications, such as the wrinkled/ slack control component, the release devices, the solar arrays, and the deployable trusses with new configurations, have been developed [28,163,164]. They may not have attracted much attention at the moment, but have promising prospects and can provide inspirations for new application development.…”

“…How to overcome or reduce the indispensable creep is a challenging issue. In 2013, Senba et al presented a novel patch-type SMP film for wrinkled/slack control of large membrane structures (figure 21) [163]. Each SMP film was pre-elongated before attaching its ends to the membrane.…”

“…Once the SMP film cooled below Tg, its shape can be fixed. Results showed that the effect of the SMP film on the wrinkled area was very localized in region close to it, and the out-of-plane displacement on the slake area was drastically reduced [163]. The stress distribution in the membrane should be considered to optimize the position of the SMP film.…”

Shape memory polymers and their composites are kind of smart materials, which can transfer from the temporarily fixed configuration to the original configuration under external stimuli. Their inherent advantages are low density, low cost, large recoverable deformation ability and controllable stimulus method, which make them an alternative for aerospace applications (deployable structures, release devices, wrinkled/slack control component, etc). Most of these applications are in development stage, some have completed the ground functional verification experiments, a rare part has been carried out the spaceflight experiments. This review focuses on their materials and structures in aerospace field, briefly introduces the development history and general mechanism of shape memory polymers and their composites, replenishes the space radiation resistance abilities of these materials under the ground-simulated space radiation experiments, tracks those applications who have already completed the spaceflight experiments, then exhibits some novel applications which have great potential and could give us inspirations for new aerospace application development, finally the prospects for materials and structures are discussed in the future outlook.

“…In their multidisciplinary project, composite corrugated skins were evaluated in terms of morphing shape realization and structural stiffness as shown in Fig 11. Shape memory polymers (SMPs) have also been considered as a candidate for morphing skins. In Japan, Senba et al applied small patched SMP films to large membrane structures in order to improve membrane surface shape (Senba et al, 2013). Out-of-plane displacement in slacking area were drastically improved with SMP films.…”

Morphing aircraft technology has recently gained attention of many research groups by its potential for aircraft performance improvement and economic flight. Although the performance of conventional control surfaces is usually compromised in off-design flight conditions, the morphing technique may achieve optimal flight performance in various operations by to adaptively altering the wing shape during flight. This paper aims to provide a comprehensive review on morphing aircraft/wing technology, including morphing mechanisms or structures, skins, and actuation techniques as element technologies. Moreover, experimental and numerical studies on morphing technologies applying those elemental technologies are also introduced. Recent research on these technologies are particularly focused on in this paper with comparisons between developments in Japan and other countries. Although a number of experimental and numerical studies have been conducted by various research groups, there are still various challenges to overcome in individual elemental technologies for a whole morphing aircraft or wing systems. This review helps for researchers working in the field related to morphing aircraft technology to sort out current developments for morphing aircraft.

“…On the other hand, there are a few studies to control shape of a wrinkled membrane using thin-film devices. Senba et al 5) suggested temperature-induced shape memory polymer patches as actuators to control wrinkle and slack of a membrane. However, they did not focus on how curved thin films make wrinkles in a flat membrane.…”

In the operation of a solar power sail IKAROS, curved thin-film solar cells were assumed to make the membrane deformed. The deformation caused propellant consumption to counteract windmill torque. For a next solar power sail in the Japan Aerospace Exploration Agency, we conducted experiments and finite element simulations of a simplified model of a part of the solar power sail to understand the effect of a small curved thin-film on wrinkles in a thin membrane under uniaxial tension force. We compared shapes of the membrane with the curved thin-film solar cell under varying tension force. Main findings are that wrinkle lines near both lateral sides of a small curved thin film are bended by curvature of the film and occur under varying tension force.
