Download or read book Life Prediction Tool for Ceramic Matrix Composites at Elevated Temperatures written by S. Case and published by . This book was released on 1998 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: A life prediction method for ceramic matrix composites is developed. This model is based upon damage mechanics concepts included in the framework of the critical element model. One unique feature of the model is its ability to include general variations of temperature and applied loads as functions of time. A detailed description of application of the model to elevated temperature fatigue is given. In addition, a validation example is presented that includes the combined effects of rupture and fatigue. The comparison with the experimental data is shown to be good, although the result does appear to be dominated by the rupture effect.

This book was released on 2003 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Ceramic matrix composite (CMC) materials are being developed for use in high temperature environments where structural integrity is critical. As part of the development, methods that can predict remaining useful life of CMC components become increasingly important. The extent of matrix cracking plays a key role in the remaining useful life of a CMC component. Therefore, as part of the effort to estimate the useful life of CMC materials, the quantification of matrix crack accumulation is critical. The objective of this work is to develop a method to estimate the amount of cracking of in-service ceramic matrix components from data acquired nondestructively. In this work, elastic properties of a CMC material system are calculated from the velocity of the first extensional mode of ultrasonic plate waves. The velocities of the extensional mode of the plate wave are used in conjunction with an elastic modulus based damage parameter to quantify matrix cracking accumulation caused by two loading conditions. The examined loading conditions are: tensile loading and tension-tension cyclic fatigue tests. The approach is demonstrated on four ceramic matrix composite material systems. These include: silicon carbide/barium-magnesium aluminosilicate (SiC/BMAS) with the BMAS matrix deposited using a slurry cast infiltration process, carbon/silicon carbide (C/SiC) material with the SiC deposited using chemical vapor infiltration, C/SiC with the SiC deposited using melt infiltration and a silicon carbide/silicon carbide (SiC/SiC) with the SiC matrix deposited using melt infiltration. As part of the work, a theoretical model based on a shear lag analysis technique is utilized which is capable of estimating the accumulation of transverse matrix cracks induced by monotonic tensile and tension-tension cyclic fatigue loading from the calculated damage parameter. As part of this work, a method is described to estimate the remaining useful life of CMC materials from the measured plate wave velocities using the shear lag model.

Book excerpt: Global population growth and tremendous economic development has brought us to the crossroads of long-term sustainability and risk of irreversible changes in the ecosystem. Energy efficient and ecofriendly technologies and systems are critically needed for further growth and sustainable development. While ceramic matrix composites were originally developed to overcome problems associated with the brittle nature of monolithic ceramics, today the composites can be tailored for customized purposes and offer energy efficient and ecofriendly applications, including aerospace, ground transportation, and power generation systems.

All over the world research is going on to develop ceramics with quasiductile behaviour. The materials with the highest potential for high temperature applications are fibre reinforced ceramic matrix composites (CMC). The international conference HT-CMC 4 in Munich will continue the tradition of its successful predecessor meetings held in Bordeaux (France, 1993), Santa Barbara (USA, 1995) and Osaka (Japan, 1998). This conference series has been recognized as the central meeting event in high temperature CMC science and technology and demonstrates the great interest in research and development on reinforced ceramics.

Download or read book Environmental Barrier Coatings written by Kang N. Lee and published by MDPI. This book was released on 2020-12-29 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: The global increase in air travel will require commercial vehicles to be more efficient than ever before. Advanced engine hot section materials are a key technology required to keep fuel consumption and emission to a minimum in next-generation gas turbines. Ceramic matrix composites (CMCs) are the most promising material to revolutionize gas turbine hot section materials technology because of their excellent high‐temperature properties. Rapid surface recession due to volatilization by water vapor is the Achilles heel of CMCs. Environmental barrier coatings (EBCs) is an enabling technology for CMCs, since it protects CMCs from water vapor. The first CMC component entered into service in 2016 in a commercial engine, and more CMC components are scheduled to follow within the next few years. One of the most difficult challenges to CMC components is EBC durability, because failure of EBC leads to a rapid reduction in CMC component life. Key contributors to EBC failure include recession, oxidation, degradation by calcium‐aluminum‐magnesium silicates (CMAS) deposits, thermal and thermo‐mechanical strains, particle erosion, and foreign object damage (FOD). Novel EBC chemistries, creative EBC designs, and robust processes are required to meet EBC durability challenges. Engine-relevant testing, characterization, and lifing methods need to be developed to improve EBC reliability. The aim of this Special Issue is to present recent advances in EBC technology to address these issues. In particular, topics of interest include but are not limited to the following: • Novel EBC chemistries and designs; • Processing including plasma spray, suspension plasma spray, solution precursor plasma spray, slurry process, PS-PVD, EB-PVD, and CVD; • Testing, characterization, and modeling; • Lifing.
