“…For the parabolic flight campaign, both the specimens and the UV curing device were designed and manufactured in-house, using the Applied Mechanics Laboratory facilities. The dimensioning of the specimens was decided after careful consideration of the manufacturing constraints within Novespace's Zero-G aircraft laboratory, the acquisition of materials and similar research performed in literature [14][15][16][17].…”

Tackling the need of more research on the field of space deployable structures, this study aims to explore the concept of space manufacturing. The target is to acquire insight that shall be useful for future deep space missions, where the in situ production of components and repair procedures shall be mission critical. In particular, the objective of this study was to deploy and cure, pneumatically actuated fiber reinforced UV polymer beam structures in micro-gravity. Then, the specimens were tested in the laboratory to identify the effects of micro-gravity on the microstructure, macrostructure, thermal and mechanical behavior of the composite material, by comparing the 0-g specimens with a 1-g control group. This research was performed by participation in the ESA-European Space Agency Fly Your Thesis! 2017 programme and the 68th ESA Parabolic Flight Campaign, through which, access to the Novespace's Zero-G aircraft laboratory was allowed.

“…The mast has excellent performance on mechanical properties when compared with a normal mast with identical cross-section. Katsumata et al [9] investigated the deployment behavior of inflatable booms with zigzag and modified zigzag folding patterns by experimental and theoretical methods. Roh et al [10] investigated the time-and temperaturedependent folding and unfolding behavior of thin-walled softenable composite boom that fabricated with woven fabric fibers and shape-memory polymer (SMP).…”

Space masts are widely used in the aerospace engineering as one type of deployable space structures. In this paper, based on the stimuli-responsive effects of shape-memory polymers (SMPs), an intelligent mast with shape-memory function is studied. The thermos-mechanical constitutive model of SMPs is associated with the finite element (FE) software, and then the deployable deformation and shape-memory effect of the intelligent mast are investigated by the FE method. It is demonstrated that the mast can automatically deploy due to the shape recovery characteristics of SMPs. Furthermore, the effects of structure parametric of the mast and temperature are also investigated. The results can contribute to the design and application of novel SMP masts.

“…Note that deployment control of inflatable tubes folded in a zigzag pattern is extremely important because inflation gas is obstructed at the folding line; a modified zigzag folding pattern shown in Fig. 1(b) has been developed on the basis of origami, as discussed in (Katsumata, et al, 2012), in which a common cavity between the upstream and downstream sides is created at the folding line. In Figs.…”

This paper discusses what has been found and what will be found using conceptual "origami" models to develop deployable space structures. The study covers the following: (i) one-dimensional structural elements, which are axially buckled inflatable tubes; (ii) two-dimensional elements, which are deployable membranes, such as solar arrays and solar sails; and (iii) deployable elements in nature. The study clarifies what design considerations are necessary to adapt the basic concepts to actual space structural hardware, and several limitations of origami models are discussed. Regarding the last subject, this study envisions future space structures using conceptual origami models that imitate three-dimensional deployable structures in nature, such as flowers and insect wings.
