By applying three steps autoclave cure process with female mold and preimpregnation honeycomb cure
process with special mold and selecting glass fabric reinforced epoxy prepreg and corresponding material, a large curvature multi-band airborne C-sandwich radome was developed. The results of electric property testing and static testing show the selection of material,structure design and process are feasible. The minimum power transmission efficiency of the radome is 84%; all parameter meet the requirement. The 200% designing load testing was successful;the radome is in agreement with structure designing specifications.
