| 摘要: |
| B4C基复合材料有一定韧性且硬度能与B4C匹配，依靠该复合材料约束B4C板，降低B4C板韧性低的不利影响，可充分发挥B4C板硬度高的优势。为获得硬度高、密度低且抗连续打击的陶瓷基复合靶板，设计了由B4C板与B4C基复合材料构成的靶板。靶板中复合材料自身是三维微观结构复合，与B4C板间的结合则是二维宏观复合。通过理论分析和试验确定靶板的制备方法和工艺。靶试显示Ф 82 mm×15 mm靶板可抗2发7.62 mm穿甲燃烧弹，防护面密度为38 kg/m2。 |

| Abstract: |
| Based on the high hardness and certain toughness of B4C ceramics based composite materials, which matches well with the high hardness of B4C ceramics, a new kind of composite armor that consists of B4C plate and B4C based composite materials was designed. To make the best use of the high hardness of B4C plate and obtain a type of armor with low density, high hardness, and continuous impacts resistance, the composite materials were used to restrict the B4C plate to lower formers’ disadvantages on toughness. In the inner part of the composite materials, the particles were bonded in a 3dimension situation, whereas the composite plate was linked with B4C plate in a planar manner. Finally, a new composite armor plate was manufactured by theoretical analysis and large quantities of experiments. A target plate with Ф 82 mm×15 mm was testified to be able to resist two 7.62 mm armor piercing incendiary projectiles，and the areal density of protection was 38 kg/m2. |
