摘要
为了探究陆基充气天线用三维大隔距机织间隔织物柔性复合材料的服役性能影响因素,分别对裁剪拼接造成的拼接强力、在酸碱工作环境中的材料强力、经折叠-展开-再折叠的耐折叠性能三大方面进行了研究。结果表明:拼接宽度为30 mm,选用胶黏剂聚氨酯A584,拼接方向夹网布经向,得到的拼接强力效果最佳,能达到反射面本体材料的断裂强力;在耐酸碱试验中,聚氨酯A584和TPU热熔胶膜均未脱胶,且表现出较好的耐腐蚀性能,表明构成反射面的各部分材料能适应天线的各种工作环境;充气反射面材料表现出较好的折叠性,其折叠性能与折叠次数、拼接宽度具有一定相关性,而与拼接用胶关系不大,拼接材料的宽度增加,折叠次数对其作用越小,折痕回复性能较好。
In order to investigate the factors influencing the service performance of flexible composites with three-dimensional large-spaced woven spacer fabrics for land-based inflatable antennas,three main aspects were investigated:the splicing strength caused by cutting and splicing,the material strength in acid and alkaline working environments,and the folding resistance after folding,unfolding and refolding.The results show that the splicing width of 30 mm,the adhesive polyurethane A584,and PVC laminated fabric warp to obtain the best splicing strength,which can reach the fracture strength of the reflective surface material.In the acid and alkali resistance test,both polyurethane A584 and TPU hot melt adhesive film did not come off,which showed good corrosion resist-ance,indicating that the materials of the reflective surface can adapt to various working environments of the antenna.The inflatable reflective surface material shows good folding performance,and its folding performance has a certain correlation with the number of folding times and splicing width,but not with the splicing glue.The width of the spli-cing material increases,the smaller the effect of the number of folding times on its role,and the folding return per-formance is better.
