“…At the highest temperature, the creep properties of the fibers do become more dominant. Figure 12 (Morscher, 2010) demonstrates this for the most creep-resistant SiC fiber type, Sylramic-iBN, reinforcing MI, CVI, and PIP matrix composites. The PIP matrix composites have the highest creep performance at 1315 • C ( Figure 12a); however, this is because they have the highest fiber volume fraction.…”

“…Current composites of interest for hot section components of jet engine are either laminate or textile (typically woven, however braided composites are possible as well). The current leading matrix type for jet engine applications is MI due to lower porosity contents and higher matrix cracking stress for this processing approach (Corman and Luthra, 2005;Morscher, 2010). Figure 5a shows the cross section of a woven fiber architecture slurry-cast MI.…”

“…(a) Creep rupture data for Sylramic-iBN woven MI composites with MI, CVI, and PIP matrices and (b) the same rupture data divided by the fiber volume fraction in the loading direction in order to relate rupture properties of the different matrix composites with relative loads on the fibers at the given temperature. Arrows indicate the specimen did not fail (Morscher, 2010 For CMCs, less information is available on the properties of composites in compression or shear as well as on out-of-plane properties. Some interlaminar shear and toughness data exist for some of the composites already discussed (Choi et al, 2009;Corman and Luthra, 2005) and many ASTM standards have been developed.…”

Ceramic matrix composites have become viable materials for jet engine applications. In particular, SiC fiber‐reinforced SiC matrix composites are being developed for hot section components of jet engine in order to reduce weight and increase temperature capability its of hot section. SiC/SiC composites can be fabricated by a variety of methods, including melt infiltration (MI), chemical vapor infiltration (CVI), and polymer infiltration pyrolysis. Composite properties vary significantly, depending on the processing approach, constituent content, and fiber architecture. Ultimately, for SiC/SiC composite performance, long‐time load‐carrying capability in oxidizing environments requires composites that have high matrix‐cracking stresses. The melt‐infiltrated composite system is the most developed SiC/SiC composite, can produce the highest matrix‐cracking stresses, and is expected to be inserted into a commercial jet engine application in the next few years. The critical factors for design associated with matrix crack formation are discussed with respect to possible composite variations within the melt‐infiltrated composite system; however, some of the trends observed should be transferable to the other composite systems described as well. In addition, current challenges for use of these materials in aero applications are discussed.

“…With a recent development of high crystalline SiC fiber, the recent strategy for high performance SiC f /SiC composites is driven to the formation of high crystalline SiC matrix in the intra-fiber bundle region of various fabric structures [5][6][7][8]. Majority of R&D researches for the property evaluation of SiC f /SiC composites were also devoted to the establishment of baseline properties such as microstructure, bending strength, tensile strength, associated with the optimization of fabricating conditions [9][10][11][12]. Among the manufacturing processes of SiC f /SiC composites, liquid phase sintering (LPS) process can be recognized as an attractive method for providing the dense SiC matrix with a high crystalline [13,14].…”

The last decade has seen the maturation of textile methods for making ceramic matrix composites with three‐dimensional (3D) fiber‐reinforcement. Such composites are much less vulnerable than traditional two‐dimensional (2D) ceramic composites to premature brittle failure, especially via delamination. Innovative textile methods also enable the creation of complex features that are formed integrally in a component as local rearrangements of the reinforcement. They also allow design of optimal fiber architectures for individual components to match the thermal and mechanical loads expected in use. This chapter begins with an introduction to conventional 2D laminate ceramic composites, including discussion of approaches that have been taken to achieve damage tolerance, the materials available for fibers, matrices, and coatings, and the rationale for selection of different materials for specific aerospace components. Several examples are then discussed of textile‐based composite components with 3D reinforcement architectures that have been developed for turbine, rocket, and scramjet applications. Some of the complexities of dealing with modeling/life prediction in these materials are discussed, along with some of the approaches for dealing with them.
