Abstract
<jats:p>The use of polymer composite materials (PCM) in space objects makes it possible to significantly reduce the weight of structures, increase their rigidity, dimensional temperature stability, and durability, which makes PCM in demand for promising orbital complexes, antenna systems, power plants, and space station frames. For space objects, it is not only the launch weight that determines the cost of delivery into orbit, but also the possibility of creating large-scale structures directly in space. Therefore, the creators of composite structures pay special attention to the possibility of using bio-like technologies, which are characterized by extremely low energy consumption in production and the possibility of simultaneously optimizing the shape of the product and the structure of its reinforcement. Natural examples being studied include composite part fasteners resembling the structure of a knot, honeycomb sandwich panel fillers resembling bee combs, bamboo-like tubular structures, and spider web-like mesh structures. Modeling and ground testing that simulate the effects of weightlessness and are necessary for verifying computational models and checking the reliability of deployable and transformable structures remain important issues. Modern methods of identification and optimization based on the processing of experimental data are used to evaluate their dynamic characteristics and refine material and geometric parameters. The possibilities of application of hybrid optimization algorithms are considered, as well as the use of multi-axis drive benches to reproduce spacecraft maneuvers. Promising additive technologies of composite structures creation and problems of robotic assembly in orbit are discussed. It was noted that further successful development of additive space 3D printing technologies is associated with the integration of interdisciplinary approaches — materials science, mechanics, system design and numerical modeling, which opens new opportunities for creating reliable and efficient space structures of the future.</jats:p>
