“…As noted earlier [31], copper screens show the greatest efficiency in the range of velocities from 7 to 10 km/s, which is associated with the evaporation of copper in the projectile-screen interaction region [14]. The action of copper vapor destabilizes a significant part of the elongated projectile, which facilitates its dispersion on the way to the barrier.…”

The protective properties of metallic and nonmetallic screens were experimentally investigated when penetrated by an aluminum shaped charge jet at collision velocities of 7–10 km/s. Such a projectile is an analog of an elongated fragment of man-made debris. For materials of protective screens, we used glass, B4C ceramics, and diamond-silicon carbide ceramic composite. The obtained results were compared with the data obtained for metal screens. In this paper, we show that the effectiveness of screen protection increases due to phase and structural transitions that occur during the interaction of elongated hypervelocity projectile with protective screens.

“…The aim of the present study is to estimate the efficiency of application of high-modulus ceramic materials in screen protection (with account for spallation [4] and other effects shaping the dynamic response of a screen to an impact) in conditions [3] simulating a collision between a fragment of space man-made debris and the duralumin structure of spacecraft.…”

“…As the impact velocity increases, other factors characterizing updated conditions of conversion of the kinetic energy of the impactor in interaction with the barrier material (e.g., phase and structural transformations under high pressures) may come into play. For example, the efficiency of application of screens made of materials with a capacity for rapid radial response to high-velocity penetration of an elongated impactor by means of partial melting and evaporation in interaction with the SP was demonstrated in [3].…”

The use of high-modulus ceramic materials under conditions simulating the screen protection of space objects from damage by fragments of space man-made debris is considered. The introduction of an aluminum jet at a speed of ~10 km/s into an aluminum barrier located behind brittle material screens was experimentally studied. A comparative analysis of the parameters of the residual cavity in the barrier made it possible to reveal the effect of the structural rearrangement of the ceramic material on the effectiveness of screen protection. Keywords: screen protection, space man-made debris, ceramic materials.
