AbstractIn order to protect space structure against space debris impacts, it is indispensable to develop a bumper shield with strength materials. The high strength fiber is one of potential materials from a viewpoint of strength, lightweight, and flexibility. The purpose of this study was to develop a single bumper shield using high strength fibers and new bumper materials against medium size debris impacts. We developed a new bumper shield using Vectran fibers and wood material. Hypervelocity impact tests were carried out by a railgun accelerator of the Institute of Space and Astronautical Science. The experimental results showed that the developed shield (the single bumper) could stop the polycarbonate projectile with 13.3 mm in diameter. 0.85 gram in weight, and 6.8 km/sec in velocity. The thickness of the new shield is about 20 mm. The projectile impacted the single bumper shield and produced a hole of 35 mm on a side. But the projectile was destroyed into the shield, and did not reach on surface of an aluminum block that is located behind the shield.
