“…Non-oxide CMCs, in particular carbon or SiC fibres reinforced SiC-based materials (C/SiC or SiC/SiC composites), have a greater potential and are more widely employed in high temperature applications such as hot section components of gas turbines (combustors, shrouds, airfoils) [1] and aerojet engines (exhaust cone, outer and inner flap, flame holder), [2] thermal protection systems of aerospace vehicles (nose cap of X-38 return vehicle), [3] advanced friction systems (brake pads and disks for passenger cars and emergency brake systems) [4] or fusion energy systems (the first wall and the blanket of a fusion reactor). [5] C/SiC and SiC/SiC composites exhibit high thermal conductivity, excellent thermal shock stability, creep resistance, oxidation resistance, wear resistance and improved toughness compared to the monolithic material.…”

The increasing interest in ecological aspects related to the reduction of harmful emissions to the atmosphere and, at the same time, the need to achieve higher efficiencies of energy production are the driving forces that justify the current development of advanced ceramic materials for high temperature applications, namely those associated to energy and transportation industries. Ceramic matrix composites (CMCs), thermal barrier coatings (TBCs), environmental barrier coatings (EBCs) and solid oxide fuel cells (SOFCs) are increasingly used to work under the new demanding conditions. In this review, the recent progress and trends in the research and development of CMCs, TBCs, EBCs and SOFCs based on ceramic materials for high temperature applications are highlighted.

This introductory article provides the background for the September 2003 issue of MRS Bulletin on Ultrahigh-Temperature Materials for Jet Engines. It covers the need for these materials, the history of their development, and current challenges driving continued research and development. The individual articles that follow review achievements in four different material classes (three in situ composites-based on molybdenum silicide, niobium silicide, and silicon carbide, respectively-and high-melting-point platinum-group-metal alloys), as well as advances in coating systems developed both for oxidation protection and as thermal barriers. The articles serve as a benchmark to illustrate the progress made to date and the challenges ahead for ultrahigh-temperature jet-engine materials.

“…Standard testing used for material characterization is therefore incapable of adequately simulating the operating environments proposed for EBC-CMCs. In an effort to investigate ceramic composites and coating systems, a number of specialized testing rigs have been developed [4,11,[17][18][19][20][21] The primary objective of the present paper is to investigate the feasibility of using ER measurements in high-temperature testing environments, specifically combined high heat-flux and mechanical loading conditions. In addition, the various NDE methods described earlier (ER, AE and DIC) are used to determine and quantify damage onset and accumulation, and CMC degradation due to the simulated engine environment exposure.…”

Environmental barrier coating (EBC) coated ceramic matrix composite (CMC) systems are currently being investigated for use as turbine engine hot-section components in extreme environments. In these extreme conditions, it becomes critical to understand material response to environmental exposure and performance under thermo-mechanical loading. Electrical resistance (ER) monitoring has recently been correlated to tensile damage accumulation in SiC/SiC CMCs, and the focus of this study is to extend the use of ER to evaluate high-temperature thermal gradient fracture of EBC/CMC systems. Tensile strength tests were performed at high temperature (1200°C) using a laser-based heat-flux technique. Specimens included an asproduced SiC/SiC CMC and coated SiC/SiC substrate that have been exposed to simulated combustion environments in a high-pressure burner rig. Localized stress-dependent damage was determined using acoustic emission (AE) monitoring and compared to full-field strain mapping using a high-temperature digital image correlation (DIC) technique. The results are compared with in-situ ER monitoring, and post-test inspection of the samples in order to correlate ER response to damage evolution.
