高能量耗散密度材料的研发是防护工程领域的研究热点.纳米多孔材料具有超大的比表面积,其与液体的相互作用能够耗散大量外界能量,因此在车辆碰撞安全等领域具有出色的应用前景.本研究选取ZSM-5沸石/NaCl溶液系统,通过准静态实验研究该系统的能量耗散行为,并阐明其机理,同时参数化地研究了沸石的前处理温度(600～1100℃)及溶液的NaC1浓度(0～2 mol/kgH2O)对系统能量耗散性能的影响.结果表明:该系统在准静态加载条件下具有较高的能量耗散密度,达到12 J/g,且可重复使用;该系统的工作性能可在较大范围内调节,其能量耗散密度与沸石前处理温度正相关,与NaCl浓度负相关;其工作压强与沸石前处理温度及NaCl浓度均正相关.本研究为开发智能、可控和高效的能量耗散系统提供了必要的基础理论与实验依据.
