摘要/Abstract

摘要： 为了研究球形陆基充气天线球面材料力学性能,在标准实验室环境里,对高强涤纶丝平纹PVC膜结构材料进行拉伸、撕裂、顶破力学性能测试;用乐泰401胶水胶接PVC膜结构材料,对不同胶接长度的材料进行拉伸性能测试;对材料在20%的盐酸和氢氧化钠溶液中腐蚀不同周期后进行拉伸性能测试。实验结果表明,球面材料经向断裂强力大于纬向;随着胶接长度的增加,断裂强力先显著增加,后趋于平缓;随着碱蚀时间的增加,沿经向和纬向的断裂强力都下降,但沿纬向的断裂强力下降幅度大于经向;PVC膜结构材料的耐盐酸性能较好;材料经向撕裂强力大于纬向;材料的顶破试样裂口形式表现为纬纱的断裂。

Abstract: To study the mechanical properties of support materials of spherical ground-based inflatable antenna, the properties of tensile, tear, bursting of high-strength polyester yarn plain weave PVC membrane fabric were investigated in a standard laboratory environment. The tensile properties were investigated in varying length of the glued material which adhered by Loctite 401 glue and in different immersion periods of hydrochloric acid and sodium hydroxide. The results showed that the warp tensile strength of support material was greater than that of the weft. The tensile strength increased at first then flattened out with the glued length increases. The tensile strength of the warp and weft both declined as alkaline etching time progresses, but the decline magnitude of weft tensile strength was greater than warp. PVC membrane materials had good resistance properties to hydrochloric acid. The warp tear strength of support material was greater than the weft and bursting specimens showed cracks in the form of weft breakage.

Key words: tensile, tear, bursting, membrane materials
