- Abstract
In order to protect spacecraft against space debris impacts, it is a feasible direction to develop a shield with high strength materials. Basalt fiber is one of the high strength, lightweight, and flexibility materials. The aim of this study was to study the damage of lightweight Whipple shield composed of basalt-glass fibers woven and AL plat. High velocity impact tests were carried out by the non-powder two-stage light gas gun facilities at Hypervelocity Impact Research Center in Harbin Institute of Technology. All tests were performed with 0.156g in mass aluminum projectile at velocity ranging from 4 to 6 km/s. The configuration of Whipple shields consisted of a bumper, a basalt-glass fibers woven and a rear wall with 10 cm space between the bumper and the rear wall. The basalt-glass fibers woven was placed in front of or behind bumper closely, and betweens bumper and rear wall. The experimental results showed that the perforation hole in AL bumper has double lips, and some fibers near the perforation hole were covered by melted AL material when the woven was placed behind the bumper. In the case of having same area density, the Whipple shield composed of basalt-glass fibers woven and AL plats gets smaller damage than all AL plats Whipple shield.
