Abstract

The present disclosure relates to a method of fabricating a composite structure using a pre-cured composite stiffener and a dry fabric component. In one example, the method includes the steps of: wrapping an adhesive film and a resin film around an edge of said pre-cured composite stiffener; inserting the edge of said pre-cured composite stiffener into a clevis of a dry fabric component to form a composite structure assembly; securing the pre-cured composite stiffener substantially perpendicularly to the base portion of the dry fabric component; and starting a consolidated infusion and cure process. The consolidated infusion and cure process applies a first temperature to the composite structure assembly for a first predetermined period of time to infuse the dry fabric component, and the increases the first temperature to a second temperature for a second predetermined period of time to cure the composite structure assembly.
