| 摘 要： | 利用球形弹和柱形弹对Kevlar/乙烯基树脂和E-玻璃纤维/乙烯基树脂三维正交机织复合材料进行弹道实验。结果表明，材料对球形弹的抗侵彻能力比对柱形弹的强；Kevlar/乙烯基树脂比E-玻璃纤维/乙烯基树脂具有更好的抗弹侵彻性能；迎弹面以压缩剪切破坏为主，而背面则以纤维拉伸破坏模式为主；z向纤维的存在，提高了三维正交机织复合材料的面内强度，使之不易发生分层、鼓包等破坏现象，其结果使得面内吸能为其主要吸能机制。

| Abstract: | Ballistic experiments were performed for Kevlar/Vinyl and E-glass/Vinyl 3D orthogonal woven composites (3D-OWC) impacted by spherical and cylindrical bullets.The results show that the anti-penetration abilities of the targets against spherical bullets are higher than those against cylindrical bullets and the absorption energy per unit area density of Kevlar/Vinyl 3D-OWC is more than that of E-glass/Vinyl 3D-OWC.The major failure mechanisms at the impact sides of the targets are shear and compression failure... |
