...Jonathan A. Salem; Subodh K. Mital; Bryan J. Harder; Aaron C. Thompson The bond strength of an environmental barrier coating (EBC) to a substrate such as a silicon carbide fiber/silicon carbide matrix (SiC/SiC) ceramic matrix composite (CMC) is a function of coating application parameters, matrix...

...N. Kedir; C. Gong; L. Sanchez; M. J. Presby; S. Kane; D. C. Faucett; S. R. Choi Erosion behavior of a large number of gas-turbine grade ceramic matrix composites (CMCs) was assessed using fine to medium grain garnet erodents at velocities of 200 and 300 m/s at ambient temperature. The CMCs used...

... components (titanium-based and nickel-based superalloys) will be replaced with ceramics and ceramic matrix composites (CMCs). These materials can survive the higher operating temperatures of future engines at significant weight savings over the current metallic components, i.e., advanced ceramic components...

... is to understand the underpinning interface science of interspersed graded ceramic/metal and ceramic/ceramic composites at the grain structure level for robust coatings and bulk material components for vehicle propulsion systems. This research enhances our understanding of the fundamental relationship between...

...Larry Lebel; Sylvain Turenne; Rachid Boukhili This paper presents an experimental procedure developed to simulate the behavior of ceramic matrix composites (CMCs) under the cyclic thermal stresses of a gas turbine combustion chamber. An experimental apparatus was assembled that produces...

...Thomas Behrendt; Stefan Hackemann; Peter Mechnich; Yuan Shi; Sandrine Hönig; Severin Hofmann; Dietmar Koch Ceramic matrix composites (CMC) offer the potential of increased service temperatures and are thus an interesting alternative to conventional combustor alloys. Tubular combustor liner...

...Nesredin Kedir; David Faucett; Luis Sanchez; Sung R. Choi Foreign object damage (FOD) behavior of an N720/alumina oxide/oxide ceramic matrix composite (CMC) was characterized at ambient temperature by using spherical projectiles impacted at velocities ranging from 100 to 350 m/s. The CMC targets...

...M. B. Ruggles-Wrenn; S. R. Hilburn Creep behavior in interlaminar shear of an oxide–oxide ceramic composite was evaluated at 1100 °C in laboratory air and in steam environment. The composite (N720/AS) consists of a porous aluminosilicate matrix reinforced with laminated, woven mullite/alumina...
