进行了弹道冲击测试计划，为开发织物防护系统中叶片脱落事件的数值模型提供验证数据。通过使用气枪向干燥的机织织物样本发射金属射弹，研究了两种不同纤维材料——Kevlar 49（E.I. DuPont Nemours and Company）和 Zylon AS（Toyobo Co., Ltd.）的冲击响应。改变并记录射弹的形状、质量、方向和速度。在大多数情况下，测试的设计是使射弹射穿样本，从而测量织物吸收的能量。这里给出的 Zylon 和 Kevlar 的结果代表了一组有用的数据，可用于建立和验证数值模型，以预测织物在模拟喷气发动机叶片释放情况的条件下的响应。此外，还对射弹方向的影响和相对性能进行了一些有用的经验观察……
A ballistic impact test program was conducted to provide validation data for the development of numerical models of blade out events in fabric containment systems. The impact response of two different fiber materials—Kevlar 49 (E.I. DuPont Nemours and Company) and Zylon AS (Toyobo Co., Ltd.) was studied by firing metal projectiles into dry woven fabric specimens using a gas gun. The shape, mass, orientation, and velocity of the projectile were varied and recorded. In most cases the tests were designed such that the projectile would perforate the specimen, allowing measurement of the energy absorbed by the fabric. The results for both Zylon and Kevlar presented here represent a useful set of data for the purposes of establishing and validating numerical models for predicting the response of fabrics under conditions simulating those of a jet engine blade release situation. In addition some useful empirical observations were made regarding the effects of projectile orientation and the relative performance of...
