    摘要:

    采用模压烧结法制备Al/Fe2O3/聚四氟乙烯(PTFE)反应材料。通过万能实验机、落锤仪以及高速摄影仪对不同配比及烧结温度下成型Al/Fe2O3/PTFE反应材料的准静态压缩力学特性及撞击感度进行了对比实验, 对其发火性能进行了分析。结果显示, 330 ℃烧结、PTFE含量为60%和70%的试件强度最高, 最大真实应力达到46 MPa。350 ℃烧结、PTFE含量为40%的试件撞击感度最高, 其特性落高H50为95 cm。Al/Fe2O3/ PTFE反应材料在受撞击发火的条件下会出现高温金属熔渣喷射现象。

    Abstract:

    The reactive Al/Fe2O3/PTFE material was prepared by molding and sintering method. The quasi-static compression feature and impact sensitivity of Al/Fe2O3/PTFE material molded in different proportioning and at different sintering temperature were comparatively tested by universal testing machine, drop hammer machine and high-speed photography instrument. Its ignition performance was analyzed. Results show that: specimens with 60% and 70% polytetrafluoroethylene(refer to as PTFE) sintering at 330 ℃ have the highest strength and the maximum real stress is 46 MPa. Specimens with 40% PTFE sintering at 350 ℃ have the highest impact sensitivity, and its characteristic drop height H50 is 95 cm. The Al/Fe2O3/PTFE material under the impact ignition conditions will appear the high temperature metal slag jet phenomenon. The research results have raised the understanding of the deformation behavior and impact reaction of Al/Fe2O3/PTFE material, which has laid a good foundation for the following research.
