Abstract

Thermite serves as a kind of representative energetic material, which is extensively applied in the civil and military fields. In this paper, PTFE/Al/FeO, PTFE/Al/MnO and PTFE/Al/MoO, solid fluorine-containing thermite with different PTFE content, were successfully fabricated by referring to the traditional thermite and adding PTFE as a binder or matrix. Quasi-static compression tests were performed to investigate the mechanical and reactive behavior of fluorine-containing thermite. SEM and XRD were employed to analyze and characterize the energetic composites and reaction residuals. The results show that all types of fluorine-containing thermite exhibited different mechanical behavior. PTFE/Al/MnO exhibited the lowest yield strength and strain hardening modulus, but the highest compressive strength and toughness. With the increase of PTFE content, the strength of fluorine-containing thermite improved. No reaction occurred when the PTFE content was 60 vol%, while fluorine-containing thermite with a PTFE content of 80 vol% experienced a severe exothermic reaction under quasi-static compression. The ignition of PTFE/Al/MoO and PTFE/Al/FeO actually attributed to the reaction of Al and PTFE, and the reaction between Al and FeO or MoO was not excited due to the insufficient input energy. The thermite reaction between Al and MnO as well as the reaction of MnO and PTFE, was induced because PTFE/Al/MnO possessed excellent ductility and absorbed the most energy during compression, accompanied with the production of Mn and MnF.

摘要

铝热剂是一种具有代表性的含能材料，在民用和军事领域都有广泛应用。本文参考传统铝热剂并添加聚四氟乙烯（PTFE）作为粘结剂或基体，成功制备了不同PTFE含量的PTFE/Al/FeO、PTFE/Al/MnO和PTFE/Al/MoO固体含氟铝热剂。进行了准静态压缩试验，以研究含氟铝热剂的力学和反应行为。采用扫描电子显微镜（SEM）和X射线衍射仪（XRD）对含能复合材料及反应残渣进行分析和表征。结果表明，所有类型的含氟铝热剂均表现出不同的力学行为。PTFE/Al/MnO的屈服强度和应变硬化模量最低，但抗压强度和韧性最高。随着PTFE含量的增加，含氟铝热剂的强度提高。当PTFE含量为60体积%时未发生反应，而PTFE含量为80体积%的含氟铝热剂在准静态压缩下发生了剧烈的放热反应。PTFE/Al/MoO和PTFE/Al/FeO的点火实际上归因于Al与PTFE的反应，由于输入能量不足，Al与FeO或MoO之间的反应未被激发。由于PTFE/Al/MnO具有优异的延展性且在压缩过程中吸收了最多的能量，并伴有Mn和MnF的生成，从而引发了Al与MnO之间的铝热反应以及MnO与PTFE之间的反应。
