1. A method for assembly of a panel structure comprising:
roll coating an adhesive onto a first edge of a first honeycomb layer, the first honeycomb layer including the first edge and a second edge; roll coating the adhesive onto a second edge of a second honeycomb layer, the second honeycomb layer including a first edge and the second edge; tacking a mesh onto the first edge of the first honeycomb layer and placing the second honeycomb layer onto the mesh so that the adhesive located upon each of the first and second honeycomb layers cures to create a structural bond between the first and second honeycomb layers and the mesh, thereby forming a honeycomb structure; locating a composite skin which includes one or more openings located through the composite skin onto the first edge of the second honeycomb layer; locating a backing plate which includes one or more openings therein onto the second edge of the first honeycomb layer; and wherein the adhesive includes an epoxy resin and contacts only exposed edges of the first and second honeycomb layers and does not cover any openings of the honeycomb structure.
