METHOD OF MANUFACTURING A HOLLOW SECTION, GRID STIFFENED PANEL

摘要

A method of manufacturing a hollow section grid-stiffened panel comprises providing a tool ( 10 ) having a surface ( 12 ). The stiffened skin composite panel is preassembled comprising laminating a composite outer skin ( 14 ) on the surface, placing a separator outer layer ( 16 ) on the composite outer skin ( 14 ), and laminating a composite stiffener ( 20 ) on the mandrel ( 18 ), the mandrel being positioned on the separator layer ( 16 ), wherein the separator layer ( 16 ) separates the stiffener ( 20 ) and the mandrel ( 18 ) from the outer composite skin ( 14 ). The preassembled outer skin composite panel is cured on the tool. The separator layer ( 16 ) and mandrel ( 18 ) are removed from the preassembled stiffened skin composite panel. The stiffened skin composite panel is reassembled, comprising applying an adhesive between the composite outer skin ( 14 ) and the composite stiffener ( 20 ). The reassembled stiffener skin composite panel is cured on the tool to bond the stiffener skin to the outer skin.
