- 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. It has high strength like Kevlar and high model like Nextel. The aim of this study was to study the damage protect property of lightweight Whipple shield composed of woven of basalt-fibers and Al plate. 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 at velocity ranging from 3 to 5 km/s. The flesh X-ray hypervelocity imaging system was used to determine the remainder velocity of the projectile. The configuration of Whipple shields consisted of a bumper (basalt fibers woven or aluminum plat) and a rear wall with 350 mm space between the bumper and the rear wall. The experimental results showed that the woven of basalt fibers can absorb the impact energy and break the body of the projectile at high velocity. The protect effect of the woven of basalt fiber are better than the aluminum plates with the same surface density. The mechanism of the scallop-shape damage of spheres was analyzed.
