Download or read book Thermal Effects on the Mechanical Properties of SiC Fiber Reinforced Reaction Bonded Silicon Nitride Matrix SiC RBSN Composites written by R. T. Bhatt and published by . This book was released on 1988 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: The elevated temperature four-point flexural strength and the room temperature tensile and flexural strength properties after thermal shock were measured for ceramic composites consisting of 30 vol % uniaxially aligned 142 microns diameter SiC fibers in a reaction bonded Si3N4 matrix. The elevated temperature strengths were measured after 15 min of exposure in air at temperatures to 1400 C. The thermal shock treatment was accomplished by heating the composite in air for 15 min at temperatures to 1200 C and then quenching in water at 25 C. The results indicate no significant loss in strength properties either at temperature or after thermal shock when compared with the strength data for composites in the as-fabricated condition. (jes).

Download or read book Effects of Interface Coating and Nitride Enhancing Additive on Properites of Hi Nicalon SiC Fiber Reinforced Reaction bonded Silicon Nitride Composites written by Ramakrishna T. Bhatt and published by . This book was released on 2000 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Strong and tough Hi-Nicalon SiC fiber reinforced reaction-bonded silicon nitride matirix composites (SiC/RBSN) have been fabricated by the fiber lay-up approach. Commercially available uncoated and PBN, PBN/Si-rich PBN, and BN/SiC coated SiC Hi-Nicalon fiber tows were used as reinforcement. The composites contained ~24 vol % of aligned 14 ♯m diameter SiC fibers in a porous RBSN matrix. Both one- and two-dimensional composites were characterized. The effects of interface coating composition, and the nitridation enhancing additive, NiO, on the room temperature physical, tensile, and interfacial shear strenght properties of SiC/RBSN matrix composites were evaluated. Results indicate that all three coated fibers, the thickness of the coating decreased from the outer periphery to the interior of the tows, and that from 10 to 30 percent of the fibers were not covered with the interface coating.

Download or read book High Temperature Mechanical Behaviour of Ceramic Composites written by Karl Jakus and published by Elsevier. This book was released on 1995-06-28 with total page 569 pages. Available in PDF, EPUB and Kindle. Book excerpt: High Temperature Mechanical Behavior of Ceramic Composites provides an up-to-date comprehensive coverage of the mechanical behavior of ceramic matrix composites at elevated temperatures. Topics include both short-term behavior (strength, fracture toughness and R-curve behavior) and long-term behavior (creep, creep-fatigue, delayed failure and lifetime). 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.

Download or read book Metal and Ceramic Based Composites written by S.T. Mileiko and published by Elsevier. This book was released on 1997-12-12 with total page 705 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modern scientific and technological fields are frequently of an interdisciplinary nature, and the field of fibrous composites is no exception. Unlike fibre-reinforced plastics, the family of metal- and ceramic-based composites is still quite a new group of materials with a large variety of mechanical and physical properties. Up until now it has been difficult to produce these materials as the necessary technical information has not been well documented.The main purpose of this book is to link together fabrication, structure and properties chains, so as to clarify which structure provides the necessary properties, and how one can attain the correct composite structure. To this end, the book not only contains topics of a purely technical nature, but also a description of the failure mechanics of metal- and ceramic-matrix composites, as this is the key to understanding the structure-properties segment of the chain mentioned.The book is divided into three parts. Part I presents a general view of composites with the accent on metal- and ceramic-matrix composites. It also contains a brief description of modern fibres and composites and can be considered, at least for beginners, as a starting point for further study. Part II looks at the composite microstructures considered to be either optimal or reasonable in resisting a particular loading. Finally Part II describes a variety of mechanical, physical, and chemical potential for organizing these microstructures. Experimental data on technologies, material structures, and material properties are used throughout the book to support theoretical conclusions or to obtain important physical parameters.
