Abstract: A molded filler material filling the voids between the nodes of dimples in a sheet of inner core double dimpled material having face sheets attached to the nodes of the dimples to form a high strength lightweight panel. This filler material forms pads having a plane surface abutting the undersurface of the face sheets and a contoured configuration abutting the core surfaces to provide a solid sandwich filler reinforcement between the face sheets at selected positions. These blocking material pads provide the desired strength and ridigity at points of attachment of the completed panel to other structure. Strips of stiffening material also may be placed throughout the interior of the panel as a means of reducing the vibration or changing vibration characteristics of the panel.

Abstract: An acoustic panel having a honeycomb core with edge members for mounting. A second honeycomb material over the first and the edge members spaces them from the decorative face sheet to prevent undesirable surface imperfections called markoff from appearing on the face sheet.
