“…Two important differences can be recognized in the various approaches: one is autonomous healing without external influence, a second one is healing with external interventions such as heat, pressure, or light. Although such approaches are not environment adaptive like in natural materials, many of such systems possess the capability to recover their original properties after damage by a process including sensing damage,1 delivering some healing agent2, 3 to the damage zone efficiently and/or providing heat,4 light,5 or other external stimuli for healing. The goal of managing the damage is to maintain the primary functionality of the material which can be related to load carrying capacity or to fluid tightness or to protective surface continuity.…”

The effect of blending on the self‐healing behavior of an ethylene/methacrylic acid copolymer ionomer is investigated. Binary EMNa/EVA and EMNa/ENR blends are studied by ballistic puncture tests. In the composition range explored (15–50 wt% of EVA and ENR), the self‐healing characteristics decrease with increasing amount of EVA but are maintained in the whole range for EMNa/ENR blends. The bullet impact zones were observed using OM. Tensile tests showed that the blending process gives the opportunity to tune the mechanical characteristics without significant loss in the self‐healing properties, particularly in EMNa/ENR blends. Component compatibility, blend morphology and thermal properties were studied using DSC, SEM, and DMTA. Molecular interactions between the phases in the blends are discussed.

“…The requirements for inflatable structure are material property (such as low mass, thin, structural endurance, very low gas infusion, and flexibility etc. ), operational lifetime (to preserve the material property for the maximum time and also to prevent the leakage), and the system level requirements (contain the need for compatible interfaces with the liner and restraint) 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 .…”

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.
