| 摘 要： | 为探究Al粉粒径对铝-聚四氟乙烯(Al-PTFE)准静态压缩反应和落锤撞击感度的影响,采用模压烧结法制备了6类不同Al粒径的Al-PTFE反应材料试件,利用万能试验机和落锤仪对6类试件进行了对比实验并用高速摄影观察,得到了不同试件的应力应变曲线及撞击感度数据,分析了Al粒径对Al-PTFE准静态压缩力学性能和落锤撞击感度的影响。结果表明,准静压实验中,Al粒径小于10μm的Al-PTFE试件发生反应,Al粒径大于10μm的试件未发生反应,落锤撞击实验中,6类试件均发生反应,随Al粒径增大,试件强度和感度随之减小,试件韧性先增后减,在6~7μm最大。在较低应变率(10-2~102 s-1)范围内,随Al粒径增大,Al-PTFE反应材料发生活化由易变难。
