Reactive material is a kind of novel impact-initiated energetic material. Understanding the mechanical property of reactive material is an important premise for its application. The tensile and impact properties of polytetrafluorethylene (PTFE)/Al series reactive materials were investigated experimentally using a universal materials testing machine and an improved pendulum impact tester at room temperature. Experimental results show that with the increasing of Al content in PTFE/Al, the tensile strength increases firstly and then decreases. When the Al content is 6%, the tensile strength achieves 36.1 MPa, which is in good agreement with the calculated result. The damage behavior of PTFE/Al is in three steps, including deformation, ductile crack and reaction. With the increasing of Al content, the toughness of PTFE/Al increases firstly, then decreases subsequently. It reaches the maximum of 72.06 J/cm2 when Al content is 40%. At the same condition, the difficulty to reaction is also enhanced and the self-sustaining reaction is suppressed.

反应材料是一种由冲击引发的新型含能材料,对其力学性能的研究是其广泛应用的一个重要前提。在室温下,利用万能试验机和改进的摆锤冲击试验机对聚四氟乙烯/铝(PTFE/Al)系列反应材料的拉伸和冲击性能进行了实验研究。随着Al含量的增加,反应材料的密度和燃烧热升高,拉伸强度呈先升高后降低的趋势,在Al含量为6%左右时达到最大值36.1 MPa,与计算结果较符合。推测反应材料的损伤过程为变形、开裂和反应3步。Al含量的增加导致反应材料试样的冲击韧性先升高后降低,在Al含量为40%左右时达到最大值72.06 J/cm2。随着Al含量的增加,材料的反应难度增加,反应自持性降低。

反应材料是一种由冲击引发的新型含能材料,对其力学性能的研究是其广泛应用的一个重要前提。在室温下,利用万能试验机和改进的摆锤冲击试验机对聚四氟乙烯/铝(PTFE/Al)系列反应材料的拉伸和冲击性能进行了实验研究。随着Al含量的增加,反应材料的密度和燃烧热升高,拉伸强度呈先升高后降低的趋势,在Al含量为6%左右时达到最大值36.1 MPa,与计算结果较符合。推测反应材料的损伤过程为变形、开裂和反应3步。Al含量的增加导致反应材料试样的冲击韧性先升高后降低,在Al含量为40%左右时达到最大值72.06 J/cm2。随着Al含量的增加,材料的反应难度增加,反应自持性降低。

Reactive material is a kind of novel impact-initiated energetic material. Understanding the mechanical property of reactive material is an important premise for its application. The tensile and impact properties of polytetrafluorethylene (PTFE)/Al series reactive materials were investigated experimentally using a universal materials testing machine and an improved pendulum impact tester at room temperature. Experimental results show that with the increasing of Al content in PTFE/Al, the tensile strength increases firstly and then decreases. When the Al content is 6%, the tensile strength achieves 36.1 MPa, which is in good agreement with the calculated result. The damage behavior of PTFE/Al is in three steps, including deformation, ductile crack and reaction. With the increasing of Al content, the toughness of PTFE/Al increases firstly, then decreases subsequently. It reaches the maximum of 72.06 J/cm2 when Al content is 40%. At the same condition, the difficulty to reaction is also enhanced and the self-sustaining reaction is suppressed.
