  • Method for co-curing perpendicular stiffeners
    Patent number: 10780611
    Abstract: A method for fabricating a composite structure is provided. A first number of layers of composite material is laid up to form a first set of stiffeners. A second number of layers of composite material is laid up to form a panel. The first set of stiffeners is associated with a first side of the panel. A pre-cured composite strip is positioned on a second side of the panel, opposite the first side. A third number of layers of composite material is laid up on the second side of the panel to form a second set of stiffeners running perpendicular to the first set of stiffeners. The pre-cured composite lies at an intersection between one of the first set of stiffeners and one of the second set of stiffeners. All the layers of composite material are co-cured to form the composite structure.
