Method of making a rigid laminated core for a structural panel

Abstract

Abstract THE METHOD OF MAKING AN ADHESIVE IMPREGNATED RIGID LAMINATED CORE STRUCTURE FOR A STRUCTURAL PANEL INCLUDING THE STEPS OF PROVIDING FIRST AND SECOND CORRUGATED SHEETS OF COMPRESSIBLE PAPER-LIKE MATERIAL, APPLYING LIQUID HEATCURABLE ADHESIVE TO THE CORRUGATED FACE OF THE FIRST SHEET TO SUBSTANTIALLY FILL THE INDENTATIONS BETWEEN THE RIDGES OF THE CORRUGATED FACE, LAYING ON THE CORRUGATED FACE OF THE FIRST SHEET A SERIES OF NON-CONNECTED SOLID WOOD BLOCKS IN LONGITUDINALLY EXTENDING ROWS TO FORM A RELATIVELY THICK LOOSE ASSEMBLY OF WOOD BLOCKS OF GENERALLY RECTANGULAR CONFIGURATION, APPLYING UNCURED LIQUID HEAT-CURABLE ADHESIVE TO THE CORRUGATED FACE OF THE SECOND SHEET IN THE SAME MANNER AS THE ADHESIVE WAS APPLIED TO THE FIRST SHEET AND THEN PLACING THE SECOND SHEET ON THE OPPOSITE SIDE OF THE ASSEMBLY OF WOOD BLOCKS WITH THE CORRUGATED FACE IN CONTACT THEREWITH. HEAT AND PRESSURE ARE APPLIED SIMULTANEOUSLY TO BOTH SIDES OF THE RESULTANT CORE ASSEMBLY TO REDUCE THE THICKNESS OF THE SHEETS, IMPREGNATE EACH OF THE SHEETS TO SOME EXTENT WITH THE ADHESIVE, CURE THE ADHESIVE AND THEREBY SECURE THE SHEETS TO THE ASSEMBLY OF WOOD BLOCKS.
