This paper aims to analyse the state-of-the-art of graphene-based materials and devices designed for use in space. The goal is to summarise emerging research studies, contextualise promising findings, and discuss underway strategies to address some specific space-related problems. To complete our overview of graphene-based technology and address the relevance of graphene in the wide scenario of the space economy, we also provide an analysis of worldwide patents and the scientific literature for aerospace applications in the period 2010–2021. We analysed global trends, country distributions, top assignees, and funding sponsors, evidencing a general increase for the period considered. These indicators, integrated with market information, provide a clear evaluation of the related technology trends and readiness levels.

“…Metal matrix composites are widely used in aerospace and automotive industries for their excellent properties such as high strength-to-weight ratio and low coefficient of thermal expansion. In recent years, fruitful results have been achieved by using nano-phase reinforced metal matrix composites such as carbon nanotubes and graphene [ 12 , 13 ], which have led to the improvement of the composites in terms of hardness, strength and wear resistance [ 14 , 15 , 16 , 17 , 18 ]. Graphene is highly preferred for its excellent mechanical properties such as high Young’s modulus and high strength.…”

Graphene has become an ideal reinforcement for reinforced metal matrix composites due to its excellent mechanical properties. However, the theory of graphene reinforcement in graphene/aluminum matrix composites is not yet well developed. In this paper, the effect of different temperatures on the mechanical properties of the metal matrix is investigated using a classical molecular dynamics approach, and the effects of the configuration and distribution of graphene in the metal matrix on the mechanical properties of the composites are also described in detail. It is shown that in the case of a monolayer graphene-reinforced aluminum matrix, the simulated stretching process does not break the graphene as the strain increases, but rather, the graphene and the aluminum matrix have a shearing behavior, and thus, the graphene “pulls out" from the aluminum matrix. In the parallel stretching direction, the tensile stress tends to increase with the increase of the graphene area ratio. In the vertical stretching direction, the tensile stress tends to decrease as the percentage of graphene area increases. In the parallel stretching direction, the tensile stress of the system tends to decrease as the angle between graphene and the stretching direction increases. It is important to investigate the effect of a different graphene distribution in the aluminum matrix on the mechanical properties of the composites for the design of high-strength graphene/metal matrix composites.

“…In many respects, graphene is considered to be an alternative to silicon device applications owing to its exceptional band structure (relatively zero bandgap) characteristics, outlining its improved optical properties and electrical competences. Besides, graphene is becoming increasingly used in the manufacture of lightweight and strong body parts for vehicles [3]. However, reproducible and stable techniques to yield larger amount and high-quality crystallite graphene at an industrial scale to compete the already commercialized silicon-based devices hold out to be the most worrisome impediment to producing graphene.…”

Herein, few layer graphene was synthesize using two arc discharge chambers of different volumes to ascertain the influence of chamber size on the quality and yield of graphene. In both arc discharge chambers (A and B), graphite rods were ignited at arc current of 200 A and pressure of 500 Torr to produce vaporized carbon atoms which were deposited on the chamber wall. The synthesized graphene was characterized using the combined effect of UV spectroscopy, X-ray diffraction, Raman spectroscopy, scanning electron spectroscopy and transmission electron spectroscopy. It was observed that, an increase in the chamber size led to an increase in the number of graphene layers (4 – 6 layers) and an increase in the crystalline size D (9.6 – 17.4 nm) as revealed by XRD results. Raman analysis shows lower value of ID/IG of 0.62 indicating the presence of lower defect in chamber A as compared to the ID/IG value of 0.93 observed in chamber B. A graphene yield of 0.96 g was obtained from chamber A while 0.67 g of the same product was obtained from chamber B. The fabricated arc discharge systems suggest that a larger chamber size could promote a better yield of graphene on an industrial scale. Hence, the research is relevant to the development of larger amounts of quality FLG for industrial device applications.
