“…An additional facesheet possessed by a Whipple shield warrants higher damage tolerance and weight efficiency than that of monolithic shielding [23]. Honeycomb-core sandwich shields were developed as an alternative to the singlepurpose protective systems [24]. Similarly to the Whipple design, a honeycomb-core sandwich panel possesses two facesheets, but attached to a honeycomb-core.…”

“…Honeycomb-core shielding incurs a channeling effect on the debris cloud as a result of the hexagonal cell structure which limits the radial expansion of the debris cloud postfragmentation [24]. Since channeled, an adverse effect is the increased concentrated areal damage on the rear facesheet, reducing the shielding effectiveness as compared to that of a Whipple shield configuration, where post-fragmentation damage is spread radially due to expansion of the fragment cloud [25].…”

“…This is especially true for CFRP, because usage increase resulted in more CFRP fragments due to mission-related debris and fragmentation debris generated by collisions and explosions in Earth's orbit [33]. Predominantly, medium-density Al projectiles were tested-experimentally and numerically-due to its widespread usage [18,21,23,24,30,31,[34][35][36][37][38][39][40][41][42]. Testing of low-(plastics) and high-density (steel and copper) projectile materials are scarcer, however some experimentation on graphite, nylon, glass, and steel has been performed [20,25,[27][28]33,43].…”

Sandwich panels are widely used in the design of unmanned satellites and, in addition to having a structural function, can often serve as shielding, protecting the satellites’ equipment from hypervelocity impacts (HVI) of orbital debris and micrometeoroids. This paper provides a comprehensive review of experimental studies in the field of HVI on sandwich panels with honeycomb- and open-cell foam cores, as well as an examination of available predictive models for the assessment of the panels’ ballistic limits. The emphasis of the review is placed on: (i) identifying gaps in the existing experimental database and the appropriate directions for its further expansion; and (ii) understanding the limitations of the available predictive models and the potential for their improvement.

“…Large sized debris are traceble while mmsized debris are not which pose a higher risk of imminent impact with the space vehicles. In 2017 Deconinck et al [65] carried a numerical study of the impact of small sized debris on honeycomb sandwich structures. The numerical results were validated by the experiments conducted at the Thiot Ingenierie Shock Physics Laboratory.…”

Safety of satellites as well as spacecrafts during space missions is a primary objective to preserve the physical and virtual assets onboard. Whipple shields belong to the class of protective equipment provided on the surface of the spacecrafts and satellites, to sustain impacts from the ultra-high speed debris, which can otherwise cause considerable damage to the corresponding structures. Recent works on whipple shields are focussed on determining the response of different geometrical arrangements and material properties under hyper-velocity impact at projectile speeds of 3-18 km/s. Advances in the whipple shield design include integrated and mechanised models employing high performance materials like fiber-metal laminates ensuring better operational capability. The forward bumper of the whipple shield is the first line of defence as it regulates the state of projectile after the primary impact. Use of aluminium alloys for front bumpers is popular, owing to their lightweight and strength characteristics. The advances for the front bumper have seen usage of ceramic, metallic foams, and super composite mixtures, which resulted in enhanced performance, durability and safety of the whipple shields. This work is a comprehensive coverage of the latest materials used for whipple shields, their performance characterization—both experimental and theoretical, and applications.
