“…Compared with the metallic material of equal areal density, the intermediate stuffing layer with fabrics could intercept and break the bulk fragments effectively, meanwhile slowing down the velocity and consuming the kinetic energy of the debris cloud. Besides, the rear plate of shielding configuration would not be damaged by the fragments produced by fiber breaking, and the damage of the rear plate would be reduced significantly [ 4 , 5 , 6 , 7 , 8 ].…”

“…The adhesion degree of Basalt and aramid fabric influences their shielding performance. The over adhesion restricts the fabric layer to absorb the kinetic energy of the debris cloud which causes the shielding performance to degrade [ 6 , 7 ]. Shear Thickening Fluid (STF) impregnated fabric composites [ 20 ] and directly curable composites [ 21 ] can be more effectively used as a bumper of a hypervelocity shield than as pure fabric layers.…”

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.
