Book excerpt: The AFOSR funded two year project (which expires March 1, 1997) addresses the effect of loading frequency and friction heating on the ambient temperature fatigue life of continuous fiber ceramic matrix composites (CFCMCs). The project, which involves mechanics modeling, mechanical testing and microscopy, examined several composite systems and has provided details concerning the damage mechanisms that occur during high frequency fatigue. The current research effort of high-frequency fatigue has been performed at the Ceramic Composites Research laboratory, in the Mechanical Engineering and applied Mechanics Department at the University of Michigan. 1. "Soft" matrix composites with strong interface bonding were shown to provide superior resistance to high frequency fatigue damage. 2. thick fiber coatings were more effective in reducing the amount of fiber wear and damage which occur during high frequency fatigue. 3. The effect of laminate stacking sequence has a profound effect on high frequency fatigue behavior of CFCMCs. 4. Surface roughness in Nicalon fibers can be determined using Atomic force Microscopy (AFM). 5. Elongated crystalline grains and a small volume fraction of whiskers in the matrix can improve the high frequency fatigue behavior of CFCMCs. 6. Loading rate was found to significantly effect monotonic tensile behavior of CFCMCs.

Download or read book Influence of Loading Frequency on the Elevated Temperature Fatigue Behavior of Fiber-Reinforced Ceramic Composites written by and published by . This book was released on 1999 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cyclic tension-tension experiments were conducted on a ceramic matrix composite of continuous Nicalon SiC-fibers in a calcium-aluminosilicate matrix. Two different stress ratios (R = sigma(min)/sigma(max)) were studied (R = 0.5 and R = 0.05) at a loading frequency of 200 Hz. Specimens tested at R = 0.05 were found to have a shorter fatigue life than specimens tested at R = 0.5. The fatigue limit (defined as run-out at 10(exp 8) cycles) increased from 212 MPa for R = 0.05 to 240 MPa for R = 0.5. Microstructural investigations revealed an internal zone with no fiber pull-out at the fracture surface, suggesting that the fatigue failures occur due to internal embrittlement. The loading condition with smallest stress range (i.e., the largest stress ratio) has the lowest amount of interfacial sliding (and thus the lowest frictional energy dissipation). It is therefore plausible that the fatigue damage is related to the amount of interfacial sliding.

Emphasis is on a review of fundamentals and on the mechanics and mechanisms underlying properties. This is the first time that complete information of elevated temperature behavior of ceramic composites has ever been compacted together in a single volume. Of particular importance is that each chapter, written by internationally recognized experts, includes a substantial review component enabling the new material to be put in proper perspective.

Book Synopsis High-Temperature Mechanical Hysteresis in Ceramic-Matrix Composites by : Longbiao Li
Download or read book High-Temperature Mechanical Hysteresis in Ceramic-Matrix Composites written by Longbiao Li and published by CRC Press. This book was released on 2022-08-09 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on mechanical hysteresis behavior in different fiber-reinforced ceramic-matrix composites (CMCs), including 1D minicomposites, 1D unidirectional, 2D cross-ply, 2D plain-woven, 2.5D woven, and 3D needle-punched composites. Ceramic-matrix composites (CMCs) are considered to be the lightweight high-temperature materials for hot-section components in aeroengines with the most potential. To improve the reliability and safety of CMC components during operation, it is necessary to conduct damage and failure mechanism analysis, and to develop models to predict this damage as well as fracture over lifetime - mechanical hysteresis is a key damage behavior in fiber-reinforced CMCs. The appearance of hysteresis is due to a composite’s internal damage mechanisms and modes, such as, matrix cracking, interface debonding, and fiber failure. Micromechanical damage models and constitutive models are developed to predict mechanical hysteresis in different CMCs. Effects of a composite’s constituent properties, stress level, and the damage states of the mechanical hysteresis behavior of CMCs are also discussed. This book also covers damage mechanisms, damage models and micromechanical constitutive models for the mechanical hysteresis of CMCs. This book will be a great resource for students, scholars, material scientists and engineering designers who would like to understand and master the mechanical hysteresis behavior of fiber-reinforced CMCs.
