中、高密度Nomex蜂窝力学性能研究

Study on the mechanical properties of the moderate and high density Nomex honeycomb

研究了航空用三种中、高密度Nomex蜂窝的力学性能 ,并讨论了纸的厚度、浸渍溶液浓度、环境湿度和渗透剂对Nomex蜂窝力学性能的影响。结果表明 ,选择厚度合适的Nomex纸 ,严格控制湿度 ,并在浓度为 35 %～5 0 %范围内浸渍胶液中加入适量的渗透剂可以制作出与国外同类产品性能相当的高性能中。

The mechanical properties of three kinds of moderate and high density Nomex honeycomb used as aeronautical materials were studied. Furthermore, the effects of aramid paper's thickness, sollvent impregrated resin's concentration and environmental moisture on the mechanical properties of Nomex honeycomb were investigated. The results show that the moderate and high density Nomex honeycomb of good quality can be produced under the following conditions:moderate thickness aramid paper is chosen, the environmental moisture is controlled strictly, and penetrating agent is added to the solvent impregnated resin whose concentration is 35%-50%. The properties of this kind of honeycomb are comparable to that of the same kind of inputed product.
