Within the 3rd funding period the development of advanced C/C-SiC ceramic matrix composite nozzle struc-tures is continued. Novel UHTC-matrix systems will be implemented into the C/C-SiC material which will in-crease the erosion and temperature stability. Novel C/C-SiC nozzle structures will be manufactured, charac-terized and tested in hot gas conditions. In cooperation with project D3 a C/C-SiC material model will be developed including the damage behavior in order to give a qualitative and quantitative lifetime prediction of complex C/C-SiC nozzle structures. Finite element analysis will be performed on C/C-SiC nozzle struc-tures including thermal and mechanical loads.

在第三个资金期间，持续的C/C-SIC陶瓷基质复合喷嘴结构的发展持续。新型的UHTC-Matrix系统将被实施到C/C-SIC材料中，该系统将不受侵蚀和温度稳定性的损害。新型的C/C-SIC喷嘴结构将在热气条件下制造，特征性和测试。将与项目D3合作开发C/C-SIC材料模型，包括损坏行为，以对复杂的C/C-SIC喷嘴结构进行定性和定量的寿命预测。有限元分析将对C/C-SIC喷嘴结构进行进行，包括热载荷和机械载荷。
