A honeycomb tabletop for use with either a vibration isolation system or a rigid support stand. The tabletop has an upper skin, a lower skin, a connecting side wall, and a honeycomb core. Additional stiffening members and structural damping treatment may also, independently, be incorporated within the honeycomb core. The upper skin of the table has a plurality of tapped holes for mounting equipment. Each hole is sealed off from the interior of the table by a closed cavity enclosure which is secured to the underside of the top skin in registration with each hole. The cavity enclosures keep residue and contaminants from passing to the interior of the tabletop and facilitate cleanup of the tabletop. The enclosures are not subjected to any loads during use of the tapped holes in the top skin. The lower skin may optionally be perforated to prevent internal pressure buildup. |
