“…62 For example, a collision with tiny meteoroids and orbital debris which is also called micro meteoroid debris (MMOD) might produce punctures or cuts which causes depressurization and gas leakage. 62,63 Since no present system of space can be autonomously repaired, there is a disastrous failure. Structures, screens, damping elements and joints are frequently used in many spatial applications.…”

Self-healing polymers (SHP) are the polymers that have the capability to recover the material from any physical damage by responding to the damages or cracks in the material and heal the same. This self-healing technology gives the polymers ability to recover from the cracks at an early stage by preventing them from any catastrophic failures, which increases the scope of applications of these materials. This review article highlights the key points on extrinsic self-healing polymer and intrinsic self-healing polymer by comparing their healing efficiency, advantages, disadvantages, and challenges in the prospect of their future development as well as their possible applications in space industry and construction of roads.

“…Objects smaller than 1 mm can lead to thermal surfaces erosion, contamination of optics and surfaces, and leaks in the fuel lines, while 1 cm size MMOD may cause fatal damage or even spacecraft destruction [7,8]. In general, contact with MMOD or other sharp objects may lead to the space structure depressurization, resulting from the creation of punctures or cuts [9,10]. In addition, impacts generate new debris, and other factors as UV radiation, charged particles or thermal cycles can worsen the damage extent [7,11].…”

In the last decade, self-healing materials have become extremely appealing for the field of space applications, due to their technological evolution and the consequent possibility of designing space systems and structures able to repair autonomously after damage arising from impacts with micrometeoroids and orbital debris, from accidental contact with sharp objects, from structural fatigue or simply due to material aging. The integration of these novel materials in the design of spacecraft structures would result in increased reliability and safety leading to longer operational life and missions. Such concepts will bring a decisive boost enabling new mission scenario for the establishment of new orbital stations, settlement on the Moon and human exploration of Mars.The proposed review aims at presenting the newest and most promising self-healing materials and associated technologies for space application, along with the issues related to their current technological limitations in combination with the effect of the space environment. An introductory part about the outlooks and challenges of space exploration and the self-healing concept is followed by a brief description of the space environment and its possible effects on the performance of materials. Self-healing materials are then analysed in detail, moving from the general intrinsic and extrinsic categories down to the specific mechanisms.

“…In addition, flexible multi-shock shields could be compressed, folded, and packaged before launch, and then, deploy as inflatable into a several-spaced shield configuration in orbit, thus resolving complications with the extended volume of rigid multi-shock shields [ 10 , 13 ]. Flexible multi-shock shields easily construct large size protective structures on orbit for deployable structures, such as the “TransHab” inflatable module [ 10 ], a Model of a flexible inflatable module RSC “Energia” [ 14 ], a Bigelow Expandable Activity Module [ 15 ].…”

In this work, the mechanical behavior and energy absorption characteristics of flexible fabric under hypervelocity impact (HVI) were investigated. Basalt fabric, ultra-high molecular weight polyethylene (UHMWPE) fabric, and aluminum alloy (Al) plate were chosen to be the sample materials for their excellent mechanical properties and applicative prospect in spacecraft shielding. HVI experiments had been conducted with the help of a two-stage light-gas gun facility, wherein Al projectile with 3.97 mm diameter was launched at velocities in the range 4.1~4.3 km/s. Impact conditions and areal density were kept constant for all targets. The microstructural damage morphology of fiber post-impact was characterized using a scanning electron microscope (SEM). Analysis results show that a brittle fracture occurred for Basalt fiber during HVI. On the contrary, the ductile fractures with large-scale plastic deformation and apparent thermal softening/melting of the material had happened on the UHMWPE fiber when subjected to a projectile impact. According to the HVI shielding performance and microstructural damage analysis results, it can be inferred that ductile fractures and thermal softening/melting of the material were the prevailing energy absorption behaviors of UHMWPE fabric, which leads to absorbing more impact energy than Basalt fabric and eventually, contributes the superior shielding performance.
