About

Walter Krenkel is a leading figure in the field of ceramic matrix composites (CMCs) and high-temperature materials, with a career dedicated to advancing lightweight structural solutions for extreme environments. His major contributions center on the development and industrialization of carbon fiber-reinforced silicon carbide (C/SiC) composites, particularly for aerospace and automotive applications. Krenkel’s pioneering work on the liquid silicon infiltration (LSI) process revolutionized the production of these materials, enabling cost-effective manufacturing while maintaining exceptional thermal and mechanical performance. His research has garnered over 3,500 citations, reflecting its profound impact on materials science and engineering. Notably, Krenkel led the development of the C/SiC brake discs used in high-performance vehicles, a breakthrough that transitioned from laboratory to commercial application. He also contributed to the design of thermal protection systems for space re-entry vehicles, demonstrating the real-world relevance of his work. As a professor at the University of Bayreuth and former head of the Ceramic Composite Structures group at the German Aerospace Center (DLR), Krenkel has mentored a generation of researchers. His recent work on robot-based fiber spray processes for small batch production highlights his ongoing commitment to bridging advanced manufacturing with practical industrial needs.
