Abstract
In order to ensure better surface smoothness of the composite honeycomb sandwich structure after scarf repair,in this paper,the effects of the compensation height of different replacement honeycomb cores and the curing temperature on the surface smoothness of the back panel of the composite honeycomb sandwich structure were stud-ied when the replacement honeycomb cores were installed.Meanwhile,the effects of the quantity of filler ply,the composite caul plate,and the surface sealing of replacement honeycomb core hole on the surface smoothness of the cured repair ply were also studied.The research results show that when the height of replacement honeycomb core is equal to the outer surface of the original structure panel or not more than 1 mm,the back panel can obtain a better surface smoothness,and the maximum bulge deformation is 0.05 mm;installing a heating blanket on the back panel side can ensure the curing temperature at the bottom when the replacement honeycomb core cures.In addition,the back panel can obtain a better surface smoothness when the replacement honeycomb core is bonded by using adhe-sive film with a lower curing temperature than the original material of panel.When three filler plies are installed be-tween the replacement honeycomb core and strucuture repair ply and a 0.4 mm caul plate is used for curing the re-pair ply,the cured repair ply can obtain a better surface smoothness,and the depression depth is 0.13 mm;when the replacement honeycomb core hole is sealing with potting compound before installing the structure repair ply.The cured repair ply can obtain a better surface smoothness.关键词
