Abstract

Abstract LAMINATED MATERIALS COMPRISING AT LEAST ONE REINFORCING LAYER PRODUCED FROM A MECHANICALLY-STABLE AND HEAT-RESISTANT YARN, IMPREGNATED WITH A HEAT-STABLE RESIN ARE FLEXIBLE AND HEAT-RESISTANT AND HAVE A HIGH RESISTANCE TO DELAMINATION. THEY ARE MADE BY FORMING AN ASSEMBLY OF ONE OR MORE LAYERS OF REINFORCING YARNS ASSOCIATED WITH A TEXTILE FABRIC CONSTITUTED BY A SOLID HEAT-STABLE POLYMER COMPOSITION, WHICH WHEN HEATED PASSES THROUGH A TRANSIENT LIQUID PHASE, AND HEATING THE ASSEMBLY TO A TEMPERATURE AND FOR A TIME SUFFICIENT TO LIQUEFY THE POLYMER COMPOSITION.
