Abstract |

[DE] Es wird ein Verfahren zur Herstellung von Keramikmatrix-Kompositen vorgestellt, das die Herstellung des Matrixpolymers unter Einsatz von Verfahren nach dem Stand der Technik ermöglicht. Bei dem Verfahren erfolgt eingangs die Herstellung eines thermoplastischen Faser-Kunstoff-Verbundwerkstoffs mit einer Faserverstärkung und einem thermoplastischen Matrixpolymer und dessen Formgebung mit Verfahren der Thermoplastverarbeitung, wie bspw. Spritzgießen. Der thermoplastische Verbundwerkstoff wird in einen duroplastischen Faser-Kunststoff-Verbundwerkstoff umgewandelt und anschließend zu Matrixkohlenstoff umgewandelt, das der Erzeugung des faserverstärkten Kohlenstoffs (C/C) unter Erzeugung des CMCs dient.
[EN] The method comprises preparing a thermoplastic fiber-plastic composite material having viscosity of 100-500 Pa.s with a fibrous reinforcement and a thermoplastic matrix polymer comprising phenol-based polymers such as novolacs or their mixtures with furfuryl components, molding the material without cross-linking, converting thermoplastic fiber-plastic composite material into a thermoset fiber-plastic composite material immediately after the injection molding, and reacting the polymer matrix with carbon matrix for forming fiber-reinforced carbon to form ceramic matrix composites. The method comprises preparing a thermoplastic fiber-plastic composite material having viscosity of 100-500 Pa.s with a fibrous reinforcement and a thermoplastic matrix polymer comprising phenol-based polymers such as novolacs or their mixtures with furfuryl components, molding the thermoplastic material without cross-linking, converting thermoplastic fiber-plastic composite material into a thermoset fiber-plastic composite material immediately after the injection molding, and reacting the polymer matrix with carbon matrix for forming fiber-reinforced carbon to form ceramic matrix composites. The composite material preparation step is performed with or without additives. The molding and the conversion steps are carried out simultaneously in a molding tool for the processing of thermoplastics. The conversion step is carried out by integrating a formaldehyde equivalent crosslinker in the thermoplastic fiber-plastic composite. The reacting step is carried out by pyrolysis to form a crack region. The method further comprises carrying out infiltration of the crack region using silcon-based group to form silicon carbide or its other compounds such boron, silicon carbonitride, siliconborocarbonitride, silicon oxycarbide, where the infiltration step is performed in the region near crack. |
