Abstract

Abstract: 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.
