Abstract
A method of constructing a honeycomb structure generally undetectable by radar. The method includes winding first and second sheets of radar absorbent material onto a central roller. A first printer prints a plurality of parallel adhesive linear deposits on the first sheet of material as it passes across the first printer. A second printer prints a plurality of parallel adhesive linear deposits on the second sheet of material as it passes across the second printer. The first and second linear deposits are offset with respect to each other. The first and second sheet materials overlap one another during winding onto the central roller. Once the first and second sheets are overlapped onto one another, the adhesive deposits secure sheets together to form a non-expanded honeycomb structure. The non-expanded honeycomb structure is removed from the central roller and is expanded to form the expanded honeycomb structure.
