Abstract
A composite structure includes a first laminate, a second laminate, and at least one core component located between the first laminate and the second laminate. The at least one core component includes a honeycomb core and at least one locking ply extending from the honeycomb core between the first laminate and the second laminate. The at least one locking ply is configured such that a pressure applied during a cure cycle of the composite structure retains the at least one locking ply between the first laminate and the second laminate thereby preventing movement of core component.
Claims5
A method of forming a composite structure comprising:
- positioning a first laminate in a molding tool;
- co-curing at least one locking ply to a honeycomb core element;
- positioning the honeycomb core element and the at least one locking ply co-cured to the honeycomb core element in the molding tool;
- positioning a second laminate over the core element, wherein the at least one locking ply extends outwardly from said honeycomb core element such that a portion of the at least one locking ply is positioned directly between the first laminate and the second laminate;
- and
- applying pressure to the second laminate thereby retaining the at least one locking ply between the first laminate and the second laminate and preventing movement of the core element.
