| 摘 要： | 通过调控金属颗粒的粒径可以显著改变W-PTFE-Al复合材料的热学特性和动态力学响应。燃烧性能测试结果表明W(7μm)-PTFE(40μm)-Al(1μm)复合材料在氩气气氛下的能量为4570.2J/g， 在氧气气氛下能量为9848.1J/g。这表明减小铝粉粒径和增大钨颗粒粒径有助于W-PTFE-Al材料能量值的提高。在冲击条件下， 四种W-PTFE-Al复合材料燃烧时间均超过500μs。随着铝粉粒径的减少，反应临界吸收功降低14%，“钝感”特性呈现下降趋势。随着钨粉粒径的减少，反应临界吸收功升高34.8%，“钝感”特性呈现上升趋势。动态压缩试验结果表明随着铝粉粒径从10μm降至1μm， W-PTFE-Al材料的抗压强度提高8.0%； 随着钨粉粒径从7μm降至100nm， W-PTFE-Al材料的抗压强度降低10.2%。
