Continuous production of composite panels,particularly for buildings

Abstract

Abstract THE CONTINUOUS PRODUCTION OF COMPOSITE STRUCTURAL PANELS EMBODYING A CONTINUOUS CORE OF CELLULAR ORGANIC OR MINERAL MATERIAL, COVERED ON ONE OR MORE FACES AND EDGES THEREOF WITH A SHEET OF HEAT-HARDENABLE RESINOUS MATERIAL, PREFERABLY REENFORCED WITH MINERAL FIBROUS MATERIAL, WHICH IS PREGELIFIED BEFORE ITS APPLICATION TO THE CORE, AND WHICH IS SUBSEQUENTLY JOINED TO THE LATTER BY PRESSING THEM TOGETHER WHILE THE RESINOUS MATERIAL UNDERGOES FINAL POLYMERIZATION AND HARDENING, PREPARATORY TO THE CONTROLLED COOLING THEREOF AND CUTTING INTO PANELS OF DESIRED LENGTH. THE FACING LAYER FOR ALL SURFACES OF THE PANEL MAY BE A UNITARY ONE HAVE AN ORIGINAL WIDTH WHICH IS AT LEAST AS GREAT AS THE PERIMETER OF THE SECTION OF THE FINISHED PANEL. COMPOSITE STRUCTURAL PANELS PARTICULARLY SUITABLE FOR WALLS, FLOORING AND PARTITIONS MAY BE FORMED WITH A FACING OF CERAMIC MATERIAL ON ONE SURFACE OF THE CORE, AND A SHEATHING LAYER OF RESIN AND REENFORCEMENT THEREFOR ENCOMPASSING THE OTHER THREE SURFACES THEREOF AND ADHERING TO THE BORDERS AT THE UNDERSIDE OF THE CERAMIC FACING LAYER. MANY IMPROVEMENTS IN THE COMPOSITE PANEL AND IN THE MODE OF MANUFACTURE THEREOF ARE ATTAINED BY INTERPOSING AN INTERMEDIATE LAYER OF FLEXIBLE MATERIAL, SUCH AS A FOAM RESIN, BETWEEN THE CORE AND THE FACING LAYERS OF THE PANEL.
