摘要
通过拉伸试验、硬度测试、扫描电镜观察(SEM)以及模拟飞行振动试验,研究了防爆铝箔网的力学性能以及飞行振动对其力学性能的影响。结果表明:防爆铝箔网的成形加工过程对其抗拉强度有显著影响。加工造成防爆铝箔厚度不均匀,使其抗拉强度测试数据表现出很大的分散性。与加工前相比,加工造成的冷作硬化效应使防爆铝箔网材料的平均抗拉强度显著提高。而飞行环境中的长期振动对防爆铝箔网的表面微观形貌、断裂行为、抗拉强度、显微硬度没有可察觉的影响。
Mechanics property of blastproof aluminum foil mesh and the effect brought on mechanics property by vi- bration test are investigated with tensile test,hardness measurement and SEM.The results show that formed processing has ob- vious effect on tensile strength of blastproof aluminum foil mesh.It makes the material thickness asymmetry,so the measurement data on tensile strength are different and dispersive,but the average value on tensile strength is improved.The other conclusion is that long-term flight vibration has little effect on the microcosmic appearance,rupture behaviour,tensile strength and rigidity of the blastproof aluminium foil mesh.
