金属基复合材料（MMCs）在特定的技术应用中是有吸引力的材料。近年来，DLR利用CVD sic纤维（主要是美国特种材料公司的SCS-6纤维）开发了mmc。sic纤维增强钛合金是近十年来发展和优化的，主要用于航空燃气轮机。由于复合材料重量轻（比重4.0），刚性强，特别适用于旋转部件。另一个应用领域的新发展是生产用于聚变反应堆和火箭推进的作为散热器材料的sic纤维增强铜合金。制备钛基和铜基复合材料的技术是通过磁控溅射在纤维表面涂覆相应的合金。通过这种方式，最初作为涂层生产的合金转化为块状基体材料，当涂层纤维堆叠在预成型中，在高温高压下进行热等静压和固结。
Metal matrix composites (MMCs) are attractive materials for specific technical applications. At DLR in recent years MMCs are developed making use of a CVD SiC-fibre (mainly the SCS-6 fibre of Specialty Materials, USA). SiC-fibre reinforced titanium alloys are developed and optimized in the past decade mainly for application in the aircraft gas turbine. As the composite material is light (specific weight 4.0) stiff and strong it is especially suitable for rotating components. A new development for another field of application is the production of SiC-fibre reinforced copper alloys as a heat sink material for application in fusion reactors and rocket propulsion. The technique to produce titanium and copper based MMCs is based on coating the fibre with the respective alloy by magnetron sputtering. In this way the alloy initially produced as a coating is transformed into bulk matrix material, when coated fibres stacked in a preform are hot-isostatically pressed and consolidated at a high temperature and pressure.
