Ceramic matrix composite (CMC) materials, made from ceramic or carbon fibers embedded in a ceramic matrix, are able to master the high temperature weakness of standard polymer based composites can be mastered. CMCs in lightweight design are representing promising material candidates that show high-grade resistance towards high temperature environment with comparatively high strength and against severe thermal shocks. In the rocket-engine realm (e.g. nozzles extensions) as well as during Earth’s atmosphere vehicle ascent and re-entry specific components are confronted with harsh thermochemical and mechanical loading [1]. Temperatures hitting the vehicle-parts can rise well above 2000 °C, while corrosive gases and particles can strongly affect their surface. Thus, thermal protection systems such as CMC-modules must withstand extreme heat in combination with significant harsh conditions. Typical Hypersonic systems refer to speeds of Mach 5 and beyond pose enormous challenges for material development, aerodynamics and thermal protection systems. The combination of composite materials and hypersonic applications is a promising field of research, as composites can better cope with the immense loads and extreme conditions in hypersonic-flight. Additionally in the field of Liquid Rocket Engines (LRE) suchlike materials are deeply considered [6]. The technical center for Ceramic Matrix Composites at ArianeGroup Germany (AGG) in Ottobrunn is covering the technologies of oxide and non-oxide ceramic composites as well as polymer composites.
Its main activity is for “Customized CMC” development for both products and respective processes – meaning, the final application with the accompanying customer requirements is always in focus to provide end-to-end solutions from design to automated manufacturing including test and inspection. With the given technical installations and facilities the full ecosystem for CMC is available for development, prototyping up to small series production.
