Method for manufacturing sandwich component for use as structural component of vehicle, involves arranging inner cover layer in tool, and arranging partial porous core layer on inner cover layer

The method involves arranging an inner cover layer (20) in a tool (100), and arranging a partial porous core layer (30) on the inner cover layer. An outer cover layer is arranged on the core layer. A process pressure is generated against the both cover layers. A core pressure is generated in the cor...

Beschreibung
Zusammenfassung:	The method involves arranging an inner cover layer (20) in a tool (100), and arranging a partial porous core layer (30) on the inner cover layer. An outer cover layer is arranged on the core layer. A process pressure is generated against the both cover layers. A core pressure is generated in the core layer to equalize the pressure against the process pressure. The plastic foam, metal foam or glass spacer fabric is used as core layer. The glass fiber composite and the carbon fiber composite are used as cover layer. Die vorliegende Erfindung betrifft ein Verfahren für die Herstellung eines Sandwichbauteils (10) für die Verwendung als Strukturbauteil eines Fahrzeugs, aufweisend die folgenden Schritte: - Anordnen einer inneren Deckschicht (20) in einem Werkzeug (100), - Anordnen einer wenigstens abschnittsweise porösen Kernschicht (30) auf der inneren Deckschicht (20), - Anordnen einer äußeren Deckschicht (40) auf der Kernschicht (30), - Erzeugen eines Prozessdrucks (P) gegen die beiden Deckschichten (20, 40), - Erzeugen eines Kerndrucks (K) in der Kernschicht (30) zum Druckausgleich gegen den Prozessdruck (P).
