Abstract
A method of manufacturing a composite panel includes manufacturing a composite panel having a first skin, a second skin, a core, and a plurality of distinct groupings of Z-axis fibers that extend through the core from the first skin to the second skin, wherein the Z-axis fibers include opposite ends respectively terminating at and integrated into the first skin and the second skin; and creating structural stringers in the composite panel by removing the second skin and substantially all of the core and the Z-axis fibers down to or adjacent to the first skin.
