| 摘 要： | 对防弹板的研究现状进行了论述，首次提出将钨纤维增强铜基复合材料与微米木纤维压制的板材通过胶接的方式进行复合制成装饰防弹板的理论。对钨纤维增强铜基复合材料的制备工艺进行了研究，并分别对制备的钨纤维增强铜基复合材料和微米木纤维板进行微观组织观察。发现钨纤维增强铜基复合材料界面结合良好，微米木纤维板中的纤维在胶接的作用下呈现有利于防弹的网状排布结构。随后对防弹板中的钨纤维增强铜基复合材料进行不同应变率条件下的压缩试验，结果显示钨纤维增强铜基复合材料具有明显的应变率敏感性，在1600s。压缩时材料的流动应力达到2350MPa，同时发现在动态压缩的过程中复合材料还出现了应变硬化和应变软化现象。研究结果表明钨纤维增强铜基复合材料具有出色的动态力学性能，利用钨纤维增强铜基复合材料构造木基装饰防弹板具有可行性。

| Abstract: | The research status of bulletproof panel was discussed, and the theory that decorating bulletproof panel was prepared with tungsten fiber reinforced copper matrix composites and panel of micron wood fibers by way of gluing was first introduced. Then the preparing technique of tungsten fiber reinforced copper matrix composites was researched, and the microstructure of the composites and micrometer wood fibers were observed. The results indicated that the interface of the composites was very well and the spatial distribution structure of micron wood fi- bers with gluing was netty, and the structure of wood fibers was favour of defending bullets. Compression tests under different strain of tungsten fiber reinforced copper matrix composites were performed, and it was shown that the composites appeared strain rate sensitivity, and the flow stress of materials achieved 2 350 MPa under 1 600 s -~ , as well as strain-hardening and strain-softening occurred during the process of dynam- ic compression. The research showed tungsten fiber reinforced copper matrix composites owned excellent mechanical properties, and it is via- ble that decorating bulletproof panel was prepared with wood and tungsten fiber reinforced copper matrix composites. |
