Book Description
The mechanical behavior of fiber-reinforced ceramic composites is closely related to their interfacial properties. The application of a single-fiber push-out test to evaluate these interfacial properties is addressed, and the stress-displacement relation during the push-out process is analyzed. The interfacial bonding, Coulomb friction at the debonded interface, Poisson's effect of the loaded fiber, residual stresses, and the interfacial roughness effect are included in the analysis. Closed-form analytical solutions are obtained. Based on these analytical solutions, a methodology is established to extract the interfacial properties from the experimental fiber push-out curve.

Book Description
The present study examined the application of a micro-indentation technique to the measurement of interfacial properties in fiber reinforced ceramic composites. Specific fiber/matrix systems included SiC/glass, SiC/macro-defect-free (MDF) cement, SiC/SiC, and mullite/glass. The effect of fiber coatings upon the interfacial properties was also investigated. These properties, which included the debond strength, interfacial shear stress, and residual axial fiber stress, were evaluated by measuring the force-displacement curves generated during load-unload cycles. Estimates of these three stress values were obtained by matching the experimental force-displacement curves with data predicted from an existing model. In general the SiC/glass composites exhibited the lowest values of the interfacial shear and debond stresses. The sliding characteristics of the SiC/MDF cement and SiC/SiC composites were strongly influenced by the residual axial stress and the nature of the fiber coating. In the case of the mullite/glass composite, the high values of the interfacial shear and debond stresses reduced the measurement sensitivity, thereby increasing the uncertainty in the estimates of the interfacial properties. 17 refs, 6 figs, 1 tab.

Book Description
Mechanical and Physical Testing of Biocomposites, Fibre-Reinforced Composites and Hybrid Composites covers key aspects of fracture and failure in natural/synthetic fiber reinforced polymer based composite materials, ranging from crack propagation, to crack growth, and from notch-size effect, to damage-tolerant design. Topics of interest include mechanical properties, such as tensile, flexural, compression, shear, impact, fracture toughness, low and high velocity impact, and anti-ballistic properties of natural fiber, synthetic fibers and hybrid composites materials. It also covers physical properties, such as density, water absorption, thickness swelling, and void content of composite materials fabricated from natural or synthetic materials. Written by leading experts in the field, and covering composite materials developed from different natural fibers and their hybridization with synthetic fibers, the book's chapters provide cutting-edge, up-to-date research on the characterization, analysis and modelling of composite materials. - Contains contributions from leading experts in the field - Discusses recent progress on failure analysis, SHM, durability, life prediction and the modelling of damage in natural fiber-based composite materials - Covers experimental, analytical and numerical analysis - Provides detailed and comprehensive information on mechanical properties, testing methods and modelling techniques

Book Description
The objectives of this program are to characterize the interfacial region in a variety of whisker and coated fiber reinforced glass ceramic matrix composites, and to study how the structure, chemistry, and bonding characteristics of the interface influence composite properties such as strength, toughness, and environmental and thermal stability. During the past year, efforts in the whisker composite area were focused on the investigation of whisker coatings such as carbon and BN on LAS glass ceramic matrix composite properties, fabrication and characterization of calcium aluminosicicate (CAS) matrix/SiC whisker composites, high resolution TEM studies of a variety of techniques, and the evaluation of SiC platelets as an alternate reinforcement to whiskers. Efforts in the coated fiber area were focused on the evaluation of yttria and BN coated NICALON fibers from General Atomics. Results of these studies are presented. Keywords: Ceramic composite interfaces, Whisker reinforced glass ceramics, LAS matrix SiC whisker composites, Coated fiber, Glass ceramic composites.
