Abstract
The purpose of this study was to develop and consider new lightweight and flexible shields composed of high strength fibers and foamed metals against medium size debris impacts. We developed three kinds of shields using Vectran sheets/fibers and SUS316L metal foams. Compared with the above conventional shield, the newly developed shields are 30 - 40 mm in thickness. Vectran sheet is composed of three layers with different functions, i.e., crashing projectiles, releasing kinetic energy and receiving fragments. Hypervelocity impact tests were carried out by a two-stage light-gas gun. The experimental results showed that the developed single bumper shield could absorb the energy created by collision of the polycarbonate, 10mm in diameter, 10mm in thickness, 1 gram in mass, flying at a speed of 2.46km/sec. We compared performance of developed shields with one of shield using JEM or previos data, examined the possibility to be useful as shield.
