Cependant, ce dernier est encore aujourd'hui la source d'accidents, souvent fatals, faute d'issue lorsqu'il intervient en vol. Dans le même temps, le besoin de réduire la masse des aéronefs actuels, pour limiter les coûts de fonctionnement, a rendu l'utilisation des matériaux composites, particulièrement réactifs au feu, indispensables. Afin de valider la performance au feu de ces matériaux, il est donc nécessaire de certifier leurs performances lorsqu'ils sont soumis au feu. Or ces essais représentent un coût non-négligeable pendant les phases de développement. L'utilisation des simulations numériques semble donc être une bonne alternative afin de limiter le nombre d'essais. Néanmoins ces dernières nécessitent un certain nombre de paramètres d'entrée et une bonne connaissance des phénomènes de dégradation. Ainsi dans ce travail, la dégradation thermique de deux matériaux composite est étudiée, le thermoplastique carbone-PEKK et le thermodurcissable carbone-phénolique. Les propriétés thermiques et cinétiques, indispensables pour la modélisation numérique du comportement au feu des matériaux, sont dans un premier temps caractérisées à petite échelle (ATG/DSC, DIL, diffusivité par méthode flash). Par la suite, ces propriétés sont utilisées dans le modèle de pyrolyse qui est validé à moyenne échelle, à l'aide de mesures de dégradation au cône calorimètre. Enfin, des essais de résistance au feu sont réalisés afin de valider les simulations numériques à grande échelle à l'aide du brûleur NexGen de la plateforme expérimental feux VESTA. De plus, les produits de pyrolyse sont évalués au cours de la dégradation (Py-GC-MS) pour déterminer les limites inférieures d'inflammabilité en fonction de la température et ainsi proposer une classification des matériaux étudiés.

Book excerpt: Ce travail de thèse s’inscrit dans le cadre d’un projet de recherche partenariale, dédié à l’utilisation de matériaux composites dans la construction navale par une approche basée sur l’ingénierie de la sécurité incendie. La motivation de ce travail a été de vérifier, de caractériser et de modéliser le comportement au feu d’un sandwich composite, préalable incontournable pour l’introduction de ce produit dans la construction navale. Pour ce faire, une méthode basée sur une approche combinée expérience-simulation, à échelle et à complexité croissantes, a été mise en œuvre. L’analyse du comportement au feu du matériau étudié a été réalisée successivement par cinq niveaux d’échelle, de l’échelle de la matière jusqu’à une échelle représentative de l’utilisation finale. La caractérisation expérimentale a été réalisée au moyen de bancs d’essais normalisés et de bancs de référence métrologique. Parallèlement, un outil de simulation numérique avancé a été utilisé pour simuler les processus de dégradation thermique, de combustion et de propagation de flamme pour ce sandwich composite. L’application pratique de ce travail a consisté in fine en l’étude du développement d’un incendie dans le cadre de simulations de scenarii d’incendie à l’échelle réelle d’un navire en structure composite

Book excerpt: Mechanical engineering, an engineering discipline borne of the needs of the in dustrial revolution, is once again asked to do its substantial share in the call for industrial renewal. The general call is urgent as we face profound issues of produc tivity and competitiveness that require engineering solutions, among others. The Mechanical Engineering Series features graduate texts and research monographs intended to address the need for information in contemporary areas of mechanical engineering. The series is conceived as a comprehensive one that covers a broad range of concentrations important to mechanical engineering graduate education and re search. We are fortunate to have a distinguished roster of consulting editors on the advisory board, each an expert in one of the areas of concentration. The names of the consulting editors are listed on the next page of this volume. The areas of concentration are applied mechanics, biomechanics, computational mechan ics, dynamic systems and control, energetics, mechanics of materials, processing, thermal science, and tribology.

Book excerpt: Preface Adhesion is a phenomenon architects and civil engineers are not very familiar with. In other disciplines knowledge about surface properties and the background of bonding energies is also far from satisfactory; nevertheless there are many important· applications in concrete engineering, where adhesion is necessary for success and durability. These include: - coating and painting - repair of concrete surfaces - bonding of fresh to old concrete - crack injection - glueing of precast elements - glueing of steel to concrete, etc. In 1981 RILEM established the technical committee 52-RAC 'Resin Adherence to Concrete'. The main aims of the committee's work were - to collect research results and practical experiences - to initiate and coordinate research programs - to develop, on a scientific base, test methods for field and for laboratory purposes. One of the results of the committee's work is a state-of-the-art report, which will be presented orally as a General Report at the International Symposium ISAP '86, and will be printed either in the RILEM journal Materials and Structures or separately. Several test recommendations have been elaborated and will be prepared as drafts for the participants ofISAP '86. These are: - direct tensile test - pull-off test - direct shear test - slant shear test - four-point bending test - dynamic loading test - thermal compatibility test (two versions) - injectibility test.

Available in PDF, EPUB and Kindle. Book excerpt: This book bridges the gap between theoretical concepts and their implementations, especially for the high-performance structures/components related to advanced composite materials. This work focuses on the prediction of various structural responses such as deformations, natural frequencies etc. of advanced composites under complex environments and/or loading conditions. In addition, it discusses micro-mechanical material modeling of various advanced composite materials that involve different structures ranging from basic to advanced, such as beams, flat and curved panels, shells, skewed, corrugated, and other materials, as well as various solution techniques via analytical, semi-analytical, and numerical approaches. This book: Covers micro-mechanical material modeling of advanced composite materials Describes constitutive models of different composite materials and kinematic models of different structural configuration Discusses pertinent analytical, semi-analytical, and numerical techniques Focusses on structural responses relating to deformations, natural frequencies, and critical loads under complex environments Presents actual demonstrations of theoretical concepts as applied to real examples using Ansys APDL scripts This book is aimed at researchers, professionals, and graduate students in mechanical engineering, material science, material engineering, structural engineering, aerospace engineering, and composite materials.

Book excerpt: The book begins with an introduction to the general problems of making measurements in high temperature and a presentation of chemically reacting flow systems. It describes each instrument with the various diagnostic techniques and discusses measurements that have been made in furnaces, flames, and rocket engines. The detailed measurement techniques described in this book cover a wide spectrum of applications in combustion systems, including gas turbine, rocket measurement techniques that were developed in laboratories. Information obtained on detailed temperature, velocity, particle size, and gas concentration distribution is leading to improve understanding of the chemical combustion process and to design imporvements in combustors.

Available in PDF, EPUB and Kindle. Book excerpt: Once treated as the absence of knowledge, ignorance today has become a highly influential topic in its own right, commanding growing attention across the natural and social sciences where a wide range of scholars have begun to explore the social life and political issues involved in the distribution and strategic use of not knowing. The field is growing fast and this handbook reflects this interdisciplinary field of study by drawing contributions from economics, sociology, history, philosophy, cultural studies, anthropology, feminist studies, and related fields in order to serve as a seminal guide to the political, legal and social uses of ignorance in social and political life.
