                  摘要: 为提升氟聚物基活性破片的毁伤效率,拓展其应用范围,研制了一种“核壳”式复合结构活性破片,该破
               片采用湿混法,引入碳纤维增强基体材料的强度,采用特定的烧结条件,制备了                             PTFE/Al/CF  钨粉和  PTFE/Al/CF  钨球
               2  种试样,并开展了相应的基本力学性能试验。通过                2  种结构破片侵彻    3 mm+3 mm+2 mm+2 mm  多层间隔铝靶试验,采
               用  Python  自编的源程序对试验数据进行自动处理,获得了各层靶板的穿孔面积、变形体积以及反应光强总量,对比分
               析了不同速度和约束条件下多层间隔靶的毁伤特征差异。结果表明:“核壳”式破片侵彻能力更强,低速可穿透                                        4  层
               靶板,但穿孔面积较小,穿孔直径约为              0.95  倍破片直径;均质破片穿孔面积更大,但侵彻能力较弱,穿孔直径约为
               1.21  倍破片直径,高速条件下只能穿透         3  层靶板;钢壳约束显著提升了破片的穿孔和侵彻能力。破片的主要活性反应
               发生在与第    2  层靶的撞击过程中,但其释能反应对穿孔效应的促进作用有限,毁伤特征差异主要取决于破片的力学特性。

               Abstract:  To enhance the damage efficiency of fluoropolymer-based reactive fragments and broaden their application range, a
               novel core-shell composite structure active fragment has been proposed. To improve the strength of the matrix material, carbon
               fiber  was  introduced  via  a  wet  mixing  method.  Under  specific  sintering  conditions,  two  types  of  samples  were  prepared:
               PTFE/Al/CF tungsten powder and PTFE/Al/CF tungsten ball. The basic mechanical properties of these samples were tested.
               The addition of tungsten powder was found to increase the dynamic compressive strength of the composite. Penetration tests
               were  conducted  on  3  mm+3  mm+2  mm+2  mm  multi-layer  interval  aluminum  targets  using  both  types  of  fragments.  The
               experimental  data  were  automatically  processed  using  a  Python-based  program,  yielding  the  perforation  area,  deformation
               volume, and reaction light intensity for each layer of the target plate. The damage characteristics of the multi-interval target
               under  different  velocity  and  constraint  conditions  were  compared  and  analyzed.  The  results  show  that  the  core-shell  type
               fragment exhibits superior penetration ability. It can penetrate all four layers of the target plates at low speeds, although the
               perforation area is relatively small, with a perforation diameter approximately 0.95 times the fragment diameter. In contrast, the
               homogeneous fragment has a larger perforation area but weaker penetration ability. Its perforation diameter is about 1.21 times
               the  fragment  diameter,  and  it  can  only  penetrate  three  layers  of  target  plates  at  high  speeds.  The  steel  shell  constraint
