1. Verfahren zum Formen eines Gegenstands aus einem Gegenstandszwischenstoff bei erhöhten Temperaturen und Drücken, beinhaltend
a) Anordnen des Gegenstandszwischenstoffes in einem Druckgefäß;
b) Anordnen eines ersten festen, fließfähigen, polymeren Mediums, das bei Temperaturen über etwa 316°C im wesentlichen thermisch stabil ist, so daß das erste Polymer in der Lage ist, einen im wesentlichen gleichmäßigen, vorbestimmten Mediumdruck auf die Oberfläche des Gegenstandszwischenstoffes zu übertragen;
c) Anordnen eines zweiten festen,fließfähigen, polymeren Mediums, so daß das zweite Polymer in der Lage ist, die Übertragung des im wesentlichen gleichförmigen, vorbestimmten Mediumdruckes auf das erste, feste, fließfähige, polymere Medium zu bewirken;
d) Bewirken, daß das zweite Medium einen im wesentlichen gleichförmigen Mediumdruck erzeugt, so daß der Druck auf die Oberfläche des Gegenstandszwischenstoffes übertragen wird; und
e) Beaufschlagen des Gegenstandszwischenstoffes mit Temperaturen über etwa 316°C;
wodurch das zweite polymere Medium vor thermischer Verschlechterung durch das erste polymere Medium geschützt wird.
• .:· .' 026&Ogr;2&Iacgr;8
