Abstract: The jet engine has been pivotal in both war and peace, propelling humanity to new heights and broadening our horizons. However, the environmental impact of fuel combustion in predominant transportation modes, like air travel, has become a growing concern due to climate change. This paper investigates how the integration of Ceramic Matrix Composites (CMCs) into the high-pressure turbine of jet engines can significantly enhance engine efficiency, reduce emissions, and lower fuel costs. It begins by outlining the fundamental principles and performance requirements of jet engines, followed by an examination of material trends and the selection process for alternative materials. The properties and manufacturing process of Silicon Carbide/Silicon Carbide (SiC/SiC) CMCs are discussed in detail. The concluding sections address the challenges associated with recycling CMCs, evaluate their benefits, and provide insights into the future applications of SiC/SiC CMCs in jet engines.
