Available in PDF, EPUB and Kindle. Book excerpt: Les composites à matrice céramique (CMC) sont des matériaux constitués d'une matrice céramique renforcée par des fibres céramiques continues (généralement à base de SiC ou de C). Le travail de thèse présenté, réalisé en collaboration avec Snecma Propulsion solide et l'Agence De l'Environnement et de la Maîtrise de l'Energie, a pour objectif d'introduire des matériaux CMC au sein de pièces de moteurs d'avions civils, concurrençant ainsi les alliages métalliques actuellement utilisés. Pour ce faire, les matériaux CMC devront répondre aux exigences propres à l'aéronautique civil, à savoir qu'ils devront présenter une longue durée de vie en atmosphère oxydante dans une gamme de basse température (400-600°C) et avoir un coût compétitif. Dans ce contexte, des matériaux CMC constitués de fibres SiC de première génération, de coût moins élevé, sont étudiés, mais leur inconvénient majeur est leur plus grande sensibilité à l'oxydation. Des matrices auto-cicatrisantes multicouches à base de Si, B, et C ont été développées ces dernières années afin d'assurer une tenue à l'oxydation des fibres, mais elles ne sont pas opérantes dans la gamme de température imposée. Compte tenu d'études précédemment réalisées et des exigences requises pour l'application visée, l'objectif du travail présenté dans ce mémoire est de proposer des solutions pour améliorer la tenue à l'oxydation de renforts fibreux à base de fibres de SiC de première génération, dans la gamme de température 400-600°C, en évitant un surcoût de production trop important.

Download or read book Augmentation de la limite lastique des composites matrice c ramique written by Bruno Abchiche and published by . This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les matériaux composites connaissent un large succès. En effet les Composites à Matrice Céramique (CMC) fonctionnant à haute température ont des performances inégalées en termes de fatigue thermomécanique. La durée de vie des CMC est pourtant limitée en raison de l'apparition précoce de fissures matricielles, ouvrant autant de portes à des environnements agressifs, entraînant un abattement prématuré des propriétés mécaniques. Arriver à retarder la fissuration matricielle devient donc une étape clé pour une future importante utilisation des CMC dans l'aéronautique ou l'aérospatial. Les travaux de cette thèse se sont inscrits dans cette logique, où pour protéger les fibres et l'interphase de l'oxydation et de la corrosion, les propriétés de la matrice céramique ont tenté d'être modifiées par l'incorporation de nanofibres en leur sein et par l'émoussement de leurs macropores résiduels.

Book excerpt: Earthen architecture constitutes one of the most diverse forms of cultural heritage and one of the most challenging to preserve. It dates from all periods and is found on all continents but is particularly prevalent in Africa, where it has been a building tradition for centuries. Sites range from ancestral cities in Mali to the palaces of Abomey in Benin, from monuments and mosques in Iran and Buddhist temples on the Silk Road to Spanish missions in California. This volume's sixty-four papers address such themes as earthen architecture in Mali, the conservation of living sites, local knowledge systems and intangible aspects, seismic and other natural forces, the conservation and management of archaeological sites, research advances, and training.

Download or read book Ceramic Materials written by Philippe Boch and published by John Wiley & Sons. This book was released on 2010-01-05 with total page 593 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is primarily an introduction to the vast family of ceramic materials. The first part is devoted to the basics of ceramics and processes: raw materials, powders synthesis, shaping and sintering. It discusses traditional ceramics as well as “technical” ceramics – both oxide and non-oxide – which have multiple developments. The second part focuses on properties and applications, and discusses both structural and functional ceramics, including bioceramics. The fields of abrasion, cutting and tribology illustrate the importance of mechanical properties. It also deals with the questions/answers of a ceramicist regarding electronuclear technology. As chemistry is an essential discipline for ceramicists, the book shows, in particular, what soft chemistry can contribute as a result of sol-gel methods.

Available in PDF, EPUB and Kindle. Book excerpt: Frank Handle ̈ 1.1 What to Expect For some time now, I have been toying around with the idea of writing a book about “Ceramic Extrusion”, because to my amazement I have been unable to locate a single existing, comprehensive rundown on the subject – much in contrast to, say, plastic extrusion and despite the fact that there are some outstanding contributions to be found about certain, individual topics, such as those in textbooks by Reed [1], Krause [2], Bender/Handle ̈ [3] et al. By way of analogy to Woody Allen’s wonderfully ironic movie entitled “Eve- thing You Always Wanted to Know about Sex”, I originally intended to call this book “Everything You Always Wanted to Know about Ceramic Extrusion”, but - ter giving it some extra thought, I eventually decided on a somewhat soberer title. Nevertheless, my companion writers and I have done our best – considering our target group and their motives – not to revert to the kind of jargon that people use when they think the less understandable it sounds, the more scienti c it appears. This book addresses all those who are looking for a lot or a little general or selective information about ceramic extrusion and its sundry aspects. We realize that most of our readers will not be perusing this book just for fun or out of intellectual curiosity, but because they hope to get some use out of it for their own endeavours.
