<p>In existing processes, the double fabric must additionally be impregnated with a thermosetting resin to obtain the desired stability. The novel process shall be simpler and quicker by comparison. …<??>In the process of the invention, the double fabric is formed from fibres or yarns made of at least one thermosetting polymer. The double fabric is then subjected to a heat treatment to consolidate the fabric. …<??>The lightweight sandwich material thus produced can be used wherever low weight and high mechanical stability are at a premium, preferably in aircraft construction.</p> |
