Investigation of residual velocity of aluminum projectiles at hypervelocity impact on woven of basalt fiber

In order to protect spacecraft against space debris impacts, it is a feasible direction to develop the shield with high strength fiber materials. The damage analysis of hypervelocity impact on high strength fiber woven is a key issue in the design of the space debris shielding, and the main content in the analysis of the dynamic behavior of materials in the hyper pressure condition. Woven of basalt fiber is one of the high strength ceramic materials concerned in recent years. The aim of this study was to study the residual velocity of aluminum projectiles at hypervelocity impact on woven of basalt-fibers. High velocity impact tests were carried out by the two-stage light gas gun facilities. The law of the velocity loss was researched according to the X-rays imaging of the projectile fragments. The residual velocity equations of aluminum projectiles were fitted from the hypervelocity impact experimental data. The study of the residual velocity equations is beneficial to the analysis of impact energy consumption of woven of basalt-fibers to aluminum projectiles.
