摘　　要：提出用一种三维结构的大隔距机织间隔织物增强PVC膜复合材料作为陆基充气天线的反射面材料。为研究反射面材料表层不同方向力学性能的差异,不同拼接材料和不同拼接宽度与拼接处断裂强力的关系以及反射面材料间隔方向拉伸能力的影响因素,对反射面材料进行了单轴拉伸试验。试验结果表明:试样材料表层的拉伸断裂强度为纬向>经向>45°方向;基布在与PVC膜复合后经纬向断裂强力提高2~3倍,45°方向断裂强力提高10倍。拼接宽度和拼接材料的断裂强度与材料拼接处的断裂强度正相关;间隔方向的抗拉伸性能与间隔纱的密度、表层织物组织结构的密度成正比,与间隔高度成反比,其中间隔丝的密度对间隔方向的抗拉伸性能影响程度最大。A three-dimensional structured woven spacer fabric reinforced PVC film composite is proposed as the reflective surface material for land-based inflatable antennas.In order to study the differences in mechanical properties of the surface layer of the reflective surface material in different directions,the relationship between different splice materials and different splice widths and the fracture strength of the splice,as well as the factors influencing the tensile strength of the reflective surface material in the spacing direction,uniaxial tensile tests were conducted on the reflective surface material.The test results show that the tensile breaking strength of the surface layer of the composite material is latitudinal>meridional>45°direction;the breaking strength of the base fabric is increased by 2~3 times in the meridional direction and 10 times in the 45°direction after the lamination of the PVC film.The fracture strength of the splice width and the splice material are positively correlated with the fracture strength of the material splice;the tensile strength in the spacer direction is proportional to the density of the spacer yarn and the density of the tissue structure of the surface fabric,and inversely proportional to the spacer height,in which the density of the spacer yarn has the greatest influence on the tensile strength in the spacer direction.
