| 摘要： | Fragment barrier systems are being examined and developed for commercial airplanes to prevent accidents as a result of an engine rotor burst failure. To use this system, it is necessary to understand how the existing aircraft materials behave under ballistic impact. The material response of 0.063, 0.125, and 0.25-inch-thick 2024 aluminum, 0.25-inch-thick Makrolon polycarbonate, and sandwich composite panels were investigated under ballistic impact. Failure modes were evaluated and ballistic limits obtained for each set of targets. The testing was done in the UC Berkeley Ballistics Laboratory using a gas gun, and a powder gun setup with a 1/2-inch diameter chrome steel spherical projectile. This report documents the testing and analysis of the UC Berkeley ballistic testing. The testing yielded excellent results on aluminum but more data is needed for titanium, composites, and polycarbonate materials. |
