Ten different ceramic matrix composite (CMC) materials were subjected to a constant load and temperature in an air environment. Tests conducted under these conditions are often referred to as stressed oxidation or creep rupture tests. The stressed oxidation tests were conducted at a temperature of 1454 deg C at stresses of 69 MPa, 172 MPa and 50% of each material's ultimate tensile strength. The ten materials included such CMCs as C/SiC, SiC/C, SiC/SiC, SiC/SiNC and C/C. The time to failure results of the stressed oxidation tests will be presented. Much of the discussion regarding material degradation under stressed oxidation conditions will focus on C/SiC composites. Thermogravimetric analysis of the oxidation of fully exposed carbon fiber (T300) and of C/SiC coupons will be presented as well as a model that predicts the oxidation patterns and kinetics of carbon fiber tows oxidizing in a nonreactive matrix.

Contains 21 papers from a May 1999 symposium on continuous fiber- reinforced advanced ceramic composites, related tests methods, materials characterization, and design applications. Papers are divided into four major categories of room-temperature test results and methods, test results and methods related to design implications, environmental effects and characterization, and damage accumulation and material development. Specific topics include notch-sensitivity of a woven oxide/oxide ceramic matrix composite, effects of microstructural damage on the thermal diffusivity of continuous fiber- reinforced ceramic matrix composites, and degradation of continuous fiber ceramic matrix composites under constant load conditions. The editors are affiliated with the University of Washington; Oak Ridge National Laboratory; and Gateway Materials Technology. Annotation copyrighted by Book News, Inc., Portland, OR.

Ceramic Matrix Composites: Lifetime and Strength Prediction Under Static and Stochastic Loading focuses on the strain response and lifetime prediction of fiber-reinforced ceramic-matrix composites under stress-rupture loading at intermediate temperatures. Typical damage mechanisms of matrix cracking, interface debonding and oxidation, and fiber’s oxidation and fracture are considered in the micromechanical analysis. Effects of composite’s constituent properties, peak stress, and testing temperature on the composite’s strain response and lifetime are also analyzed in detail. Finally, a comparison of constant and different stochastic stress spectrum on composite’s damage evolution and fracture is discussed. This book will be a practical guide for the material researcher and component designer needing to better understand the composite’s damage and fracture behavior under stress-rupture loading at intermediate temperatures. Contains detailed analysis of the stress-rupture behavior of fiber-reinforced ceramic-matrix composites Includes experimental data on stress-rupture behavior of different CMCs Presents micromechanical constituent models for characterizing damage and fracture behavior under stress-rupture loading Provides data on the physical properties of each constituent at various temperatures, along with the composite’s response

High Temperature Mechanical Behavior of Ceramic-Matrix Composites Covers the latest research on the high-temperature mechanical behavior of ceramic-matrix composites Due to their high temperature resistance, strength and rigidity, relatively light weight, and corrosion resistance, ceramic-matrix composites (CMCs) are widely used across the aerospace and energy industries. As these advanced composites of ceramics and various fibers become increasingly important in the development of new materials, understanding the high-temperature mechanical behavior and failure mechanisms of CMCs is essential to ensure the reliability and safety of practical applications. High Temperature Mechanical Behavior of Ceramic-Matrix Composites examines the behavior of CMCs at elevated temperature—outlining the latest developments in the field and presenting the results of recent research on different CMC characteristics, material properties, damage states, and temperatures. This up-to-date resource investigates the high-temperature behavior of CMCs in relation to first matrix cracking, matrix multiple cracking, tensile damage and fracture, fatigue hysteresis loops, stress-rupture, vibration damping, and more. This authoritative volume: Details the relationships between various high-temperature conditions and experiment results Features an introduction to the tensile, vibration, fatigue, and stress-rupture behavior of CMCs at elevated temperatures Investigates temperature- and time-dependent cracking stress, deformation, damage, and fracture of fiber-reinforced CMCs Includes full references and internet links to source material Written by a leading international researcher in the field, High Temperature Mechanical Behavior of Ceramic-Matrix Composites is an invaluable resource for materials scientists, surface chemists, organic chemists, aerospace engineers, and other professionals working with CMCs.

This book investigates the time-dependent behavior of fiber-reinforced ceramic-matrix composites (CMCs) at elevated temperatures. The author combines the time-dependent damage mechanisms of interface and fiber oxidation and fracture with the micromechanical approach to establish the relationships between the first matrix cracking stress, matrix multiple cracking evolution, tensile strength, tensile stress-strain curves and tensile fatigue of fiber-reinforced CMCs and time. Then, using damage models of energy balance, the fracture mechanics approach, critical matrix strain energy criterion, Global Load Sharing criterion, and hysteresis loops he determines the first matrix cracking stress, interface debonded length, matrix cracking density, fibers failure probability, tensile strength, tensile stress-strain curves and fatigue hysteresis loops. Lastly, he predicts the time-dependent mechanical behavior of different fiber-reinforced CMCs, i.e., C/SiC and SiC/SiC, using the developed approaches, in order to reduce the failure risk during the operation of aero engines. The book is intended for undergraduate and graduate students who are interested in the mechanical behavior of CMCs, researchers investigating the damage evolution of CMCs at elevated temperatures, and designers responsible for hot-section CMC components in aero engines.
