Methods for manufacturing an i-stringer of an aircraft and devices for use in such methods |
摘要 |
Methods for manufacturing a reinforced composite structure for an aircraft and devices used in such methods are provided. A method includes advancing a composite material layout through a cap-forming device. The advancing results in a preformed cap section, a first length of the layout and a second length of the layout. The layout is removed from the cap-forming device and the preformed cap section of the layout is arranged within a cavity of a flexible mandrel with a foot portion of the first length and a foot portion of the second length remaining outside the cavity of the flexible mandrel. The foot portion of the first length and the foot portion of the second length contact a skin structure. The layout is heated and pressurized using the flexible mandrel to cure the layout and form the reinforced composite structure affixed to the skin structure. |

1. A method for manufacturing a reinforced composite structure for an aircraft, the method comprising the steps of:
forming a composite material layout by arranging a first composite material ply overlying a second composite material ply and positioning a pre-cured cap insert on the first composite material ply; advancing the composite material layout through a cap-forming device, wherein the advancing results in a preformed cap section, a first length of the composite material layout and a second length of the composite material layout; removing the composite material layout from the cap-forming device; arranging the preformed cap section of the composite material layout within a cavity of a flexible mandrel with a foot portion of the first length and a foot portion of the second length remaining outside the cavity of the flexible mandrel; contacting the foot portion of the first length and the foot portion of the second length with a skin structure: and heating and pressurizing the composite material layout using the flexible mandrel to cure the composite material layout and form the reinforced composite structure affixed to the skin structure. |
