TLDR
A method and apparatus for manufacturing a composite structure is described in this article. But this method requires the use of a filler material with a barrier material for a channel in the filler material.Abstract:
A method and apparatus for manufacturing a composite structure. A filler material with a barrier material for a channel in the filler material is formed. A composite material and the filler material with the barrier material are laid up onto a tool in a shape of the composite structure. The composite material and the filler material in the shape of the composite structure are cured.read more

Processes to fabricate composite tubular-reinforced panels integrating skin and stringers and the panels thereby fabricated
TL;DR: In this paper, an integrated fiber-reinforced cured resin-composite panel structure is constructed by forming a panel pre-form assembly by positioning pre-cured fiber re-inforced reinforced resincom composite tubular stiffeners onto an uncured base skin, and then applying uncured fiber reinforced resin composite overlapping layers onto the precured stiffeners so that at least lateral edges of overlapping layers are laminated to a corresponding region of the base sheet.
