摘要:
为研究PTFE/Al/Fe2O3反应材料在准静态压缩和落锤撞击条件下的力学响应和反应特性,在PTFE/Al基础配方中加入不同体积分数的Fe2O3,制备了PTFE/Al/Fe2O3三元反应材料,采用扫描电子显微镜(SEM)和X射线衍射仪(XRD)对材料进行了表征,并用准静态压缩和落锤撞击试验研究了材料的力学和反应性能。结果表明,随着Fe2O3含量的增加,PTFE/Al/Fe2O3反应材料压缩强度先增加后减小,当Fe2O3体积分数为15%时,材料的压缩强度达到最大,为88MPa;含Fe2O3体积分数5%的反应材料在准静态压缩和落锤撞击条件下均能发生剧烈的爆炸反应,但对其反应产物的XRD分析表明,Fe2O3与Al之间的铝热反应并未被触发;Fe2O3体积分数为15%和25%的反应材料在准静态压缩条件下未见发火现象,但在落锤撞击试验中,发生了剧烈的爆炸和燃烧,并在其反应产物中检测到了AlF3、Al2O3、Fe、FeF2、FeO(OH)的衍射峰,表明发生了铝热反应。
Abstract:
To study the mechanical response and reaction characteristics of PTFE/Al/Fe2O3 reactive materials under the condition of quasi-static compression and drop-weight impact. The PTFE/Al/Fe2O3 ternary reactive materials were prepared by adding different volume fractions of Fe2O3 to the basic formulation of PTFE/Al. The materials were characterized by scanning electron microscopy (SEM) and X-ray diffractometer (XRD). The mechanical properties and reaction properties of the materials were studied by quasi-static compression and drop-weight impact tests. The results indicate that with the increase of Fe2O3 content, the compression strength of PTFE/Al/Fe2O3 reactive materials increases first and then decreases. When the volume fraction of Fe2O3 is 15%, the compression strength of the material reaches the maximum of 88MPa. The reactive material containing Fe2O3 with volume fraction of 5% can undergo violent explosion reaction under the condition of quasi-static compression and drop-weight impact, but the XRD analysis of the reaction products shows that the thermite reaction between Fe2O3 and Al does not trigger. The reactive materials with 15% and 25% Fe2O3 are not fired under the condition of quasi-static compression, but in the drop-weight impact test, severe explosion and combustion occurred, and the diffraction peaks of AlF3, Al2O3, Fe, FeF2,FeO(OH) are detected in their reaction products, indicating that the thermite reaction occurs.
