The project deals with novel metal/ceramic composites for long-term use as high-performance thermal conductors in the fields of power electronics and fusion reactors. The aim of the project is the exploration of interpenetrating copper/ceramic composites exhibiting high thermal conductivities. Advanced testing methods are applied to characterize the thermocyclic degradation of these materials. In the first stage, the project will be focused on copper/alumina composites, small amounts of which have been produced successfully at Aalen University of Applied Sciences. With improved processing equipment these composites will be produced at a larger scale and reproducible quality. Testing methods established at KIT will be applied for the characterization of the degradation under thermocyclic loading on samples in the size range 5-50 mm. The focus will be on the interaction between mechanical and thermophysical properties. In parallel, interpenetrating copper/silicon carbide composites will be produced. These composites may exhibit even higher thermal conductivities due to the better performance of silicon carbide. These attractive materials will be characterized as well with respect to their process-microstructure-properties interrelationship.

该项目涉及新型金属/陶瓷复合材料，可长期用作电力电子和聚变反应堆领域的高性能导热体。该项目的目的是探索具有高导热性的互穿铜/陶瓷复合材料。采用先进的测试方法来表征这些材料的热循环降解。在第一阶段，该项目将专注于铜/氧化铝复合材料，其中少量已在Aalen应用科学大学成功生产。随着加工设备的改进，这些复合材料将以更大的规模和可重复的质量生产。在KIT建立的试验方法将用于表征尺寸范围为5-50 mm的样品在热循环载荷下的降解情况。重点是机械和热物理性能之间的相互作用。与此同时，将生产互穿铜/碳化硅复合材料。由于碳化硅的更好性能，这些复合材料可以表现出甚至更高的热导率。这些有吸引力的材料将被表征，以及相对于它们的工艺-微观结构-性能的相互关系。
