대표청구항 ▼

What is claimed is: 1. A method for manufacturing a hollow composite stringer, the method comprising:forming foam with a mandrel installed into the foam;laying up a composite material and the foam with the mandrel installed into the foam onto a tool in a form of a stringer, wherein the composite material defines an elongated first channel of the stringer and wherein the foam with the mandrel installed into the foam is located within the first channel;curing the composite material and the foam with the mandrel installed into the foam in the form of the stringer to form a cured stringer;removing the mandrel from the foam to form a second channel in the foam; andplacing the composite material and the foam on a skin ply such that the foam with the second channel formed in the foam is positioned between the composite material and the skin ply.
