Abstract: The radome requires large external dimensions and the weight saving. The hollow sandwich composite material can meet the requirements of transmitting wave and light high-strength. Based on the above requirement and actual condition, this paper puts forward the choice of glass fiber reinforced epoxy resin composite material for skin, and three-dimensional hollow fabric composite material for the core material of A sandwich structure radome. This article uses finite element analysis software to establish the three-dimensional finite element model of hollow sandwich radome, and the radome stiffness, strength and stability under the operating conditions are analyzed. The calculation results meet the requirements of stiffness, strength and stability. And, the pressure test verifies that the deformation of hollow sandwich radome is consistent with the results of finite element analysis, which provides guidance for the layer design, material selection and optimization of the radome.

Key words: three-dimensional hollow fabric, hollow fabric composite material, radome, the finite element analysis
