Title:
METHOD AND SYSTEM FOR FORMING COMPOSITE STRINGER ASSEMBLY
Document Type and Number:
Japanese Patent JP2022094916
Kind Code:
A
Abstract:
To provide a method and a system for manufacturing a composite stringer assembly.SOLUTION: A system comprises a bladder 110 having a bladder core 120 and a bladder skin 130. The bladder core is a foam. The bladder skin is formed from an elastic material and encloses the bladder core. When a composite stringer assembly is manufactured, the bladder is positioned over a charge base 182. The charge base becomes a constituent of a stringer base, such as a fuselage or a wing skin plate. A charge hat 180 is then positioned over the bladder and is conformed to the bladder. A combination of the bladder skin and the bladder core functions as a support structure while the stringer assembly is cured during this manufacturing operation. In some examples, the bladder core is collapsible for removal of the bladder from a cavity of the stringer assembly.SELECTED DRAWING: Figure 13C-13D
