Abstract
A composite material includes a honeycomb layer with top and bottom sides. The honeycomb layer includes a plurality of walls defining a plurality of cells therein. A first adhesive layer is disposed adjacent to the top side of the honeycomb layer. A second adhesive layer is disposed adjacent to the bottom side of the honeycomb layer. A third adhesive layer is disposed adjacent to the first adhesive layer on the top side of the honeycomb layer. A first composite layer is disposed adjacent to the third adhesive layer on the top side of the honeycomb layer. A second composite layer is disposed adjacent to the second adhesive layer on the bottom side of the honey comb layer. At least the third adhesive layer comprises viscous properties that discourage the creation of channels within the first composite layer when co-cured.
