ABSTRACT:
A composite lead sheet product comprising a layer of lead or lead alloy having first and second surfaces. A first layer of a porous, non-metallic material is mechanically bonded to the first surface of the lead layer, and a second layer of porous, non-metallic material is mechanically bonded to the second surface of the lead layer. The method of making the composite of this invention comprises supporting a first layer of a porous, non-metallic sheet material on a heat sink. Molten lead or lead alloy is dispensed transversely across the first layer. A second layer of a porous, non-metallic sheet material is applied over the dispensed molten lead. The second layer is pressed into the molten lead, and the molten lead is pressed into the first layer with a roller, to mechanically bond the first and second layers to the lead.
