Research on Forming Technology of Composite Honeycomb Sandwich Structure for Helicopter Conformal Antennas
On the one hand,the characteristics and forming difficulties of honeycomb sandwich structure of conformal antenna are analyzed.On the other hand,the quality of conformal antenna is improved by layup optimization,radiator surface treatment,honeycomb precuring and co-curing process parameter adjustment.The trial production of the product shows that when forming the U-shaped conformal antenna,the honeycomb is preformed first,and then the honeycomb,the radiator and the skin are co-cured,the good quality conformal antenna can be obtained,and the adhesion between the skin,the honeycomb and the radiator is not easy.At the same time,setting reasonable temperature parameters during the co-curing process can effectively reduce the deformation of the product and ensure its appearance quality.
