A dauber assembly may comprise a manifold body comprising a first end configured to receive a nozzle, and a collar extending at least partially around the manifold body. The collar may comprise an inlet port. The manifold body may have one or more holes providing fluid communication between the inlet port of the collar and an outlet of a nozzle received by the first end of the manifold body.

Systems and methods for curing complex fiber-reinforced composite structures utilize two distinct heat sources. A first heat source is utilized for heating a complex fiber-reinforced composite structure from within an internal portion of the complex fiber-reinforced composite structure. A second heat source is utilized for heating the complex fiber-reinforced composite structure from an external surface of the complex fiber-reinforced composite structure.

A structural core and associated method of forming such structure is disclosed. The structure includes a single layer of at least two rows of hollow pyramid-like structures. The hollow pyramid-like structures dampen acoustic noise and provide a truss-like structure that provides a high level of stiffness against transverse loads, shear stresses and side-loading. The hollow pyramid-like structures preferably have upward facing and downward facing open bases, and are formed in rows and columns. To aid in sound attenuation, the single layer is formed from a partially porous material, a woven thermoplastic, woven carbon fiber, fiberglass and paper. To provide additional structural integrity, the single layer is formed from a solid non-porous material such as a metal. The structural core may be included within outer panels to form acoustical or structural panels.
