Verfahren zur Herstellung eines monolithischen, doppelwandigen und hitzebeständigen Verbundwerkstoffteiles und danach hergestelltes Verbundwerkstoffteil |
摘要 |
Thermo-structural component (20) is made from two layers (21, 22) of a composition material, e.g. based on carbon fibres, joined together by spacers (23) formed by stitches of a filament passed through the outer skins and an intermediate core of a supple material through which a needle can pass. The resulting sandwich structure is then impregnated with a viscous resin and after the resin has set, the core is eliminated by pyrolysis to leave the two skins with spacers in the gap between them |
