Six distinct high-performance fabrics, Aluminum (Al) mesh, and 5A06 Al plates were considered as experimental samples, and the areal density were kept constant for all shielding configuration. HVI experiments were carried out by the two-stage light gas gun capable of accelerating 3.97 mm diameter Al projectiles to 4.0 ~ 4.2 km/s. An evaluation methodology of absorbed energy was proposed to analysis the energy absorption of multiple fabrics in HVI experiments, which based on initial velocity of projectiles, penetrated layers in fabric targets, the depth and volume of the impact crater on witness plate. It was found that UHMWPE and aramid fabric targets were not penetrated, and had a higher energy absorption capacity, exhibiting excellent shielding performance compared to other materials of the same area density.

Keywords: Hypervelocity impact; Space debris; Multiple fabrics. Shielding performance; Energy absorption. 1. Introduction The shielding structures of spacecraft is critical due to the increase of micro-meteoroid and orbital debris (MMOD) on earth orbit. High-performance fabrics are being increasingly employed in MMOD shielding because of their excellent properties such as high specific strength, specific modulus, energy absorption and corrosion resistances Fracture, Damage and Structural Health Monitoring Energy absorption evaluation of multiple fabrics under hypervelocity impact loading Huadong Xu 1 , Jia Zhou 2* , Xu Cao 1 , Wenxiang Liu 1 , Changqing Miao 1 † 1 National Key Laboratory of Science and Technology on Advanced Composites in Special Environment, Harbin Institute of Technology, Harbin 150001, China. 2 School of Water Conservancy & Civil Engineering, Northeast Agricultural University, Harbin 150001, China.
