Abstract: In this paper, FiberSIM composite software was used to simulate the best lay-up method, and the results of software simulation were used to make the inner contour cutting samples of the inner and outer skin. The design angle alignment of the tooling accurately controls the inner and outer skin lay-up joints to ensure the uniformity of the space distribution of the inner and outer skin. The honeycomb cutting template is used to cut the honeycomb to ensure that the honeycomb joint is tightly stitched, which avoids the influence of styrofoam in the honeycomb joint on the electric thickness uniformity. Suitable curing parameters were used to shape the inner and outer skin, bonding honeycomb and block respectively to ensure the uniform distribution of adhesives on the curved radome. The radome made by the above method has good uniformity of electric thickness. The amplitude consistency can be controlled within ±0.1 dB, and phase consistency can be controlled within ±3°, which is better than the design requirements. Under the simulated wind speed of 45 m/s and 65 m/s,the maximum shape variable of the radome meets the design requirements.
