Book Description
The production of high-purity ceramic materials from low-molecular weight, inorganic or organoelement precursors is a topic of increasing relevance within materials science. With this emerging technology it is possible to precisely tailor the properties of the ceramic material which enables new high-temperature or electronic applications. Every materials scientist and engineer involved in the research and development of new high-performance ceramic materials will find these results - presented at a recent workshop of the Max-Planck-Gesellschaft - of great importance for his own work.

Book Description
As humans entered 21st century, the energy crisis has gained more attention and reached a critical situation that may impede the further innovation of science and technology. Along with the development of the Internet and wireless communication, electronic devices, from automated production robots down to small consumer electronics, are overtaking our lives at a rate that none of the conventional industries can compete with. This leads to the ever-growing demand for energy production, transportation, and storage. In addition to the investigations on clean or renewable energy sources, more researches are promoting the efficiency of generating or utilizing the already existed forms of energy. Aerospace related development and applications consume a significant amount of resources. As a critical unit of aerospace application, turbine engines may be effectively advance by the reliable high-temperature components in not only the performance but the efficiency. Fiber-reinforced ceramic matrix composites (FRCMCs) are proposed as the next-gen material of turbine high-temperature components (such as turbine blades, shrouds, combustor liner, exhaust nozzle, etc.), with high oxidation and creep resistance and outstanding mechanical performance at elevated temperatures but lower density than single crystals. Within the CMCs, ceramic fibers serve as the major performance support. Polymer derived ceramics (PDCs) or polymer derived ceramic route is an innovated ceramic production technique, developed over the last half-century, that begins with the synthesis or the selection of monomer molecules (therefore also known as molecular methods); fine-tunes at the precursor stage; shapes during crosslinking stage; and converts the organic components into inorganic ceramics via pyrolysis. This method enables the synthesis of uniform ceramic fibers at a much lower temperature and easier processing condition than conventional powder-based synthesis. PDC fibers (SiC, Al2O3, BN, etc.) have already shown great potential in high-temperature applications as reinforcement of CMCs. This thesis focus on the synthesis and characterization of ceramic fibers from silicon-based liquid-phase precursors. The fibers are drawn using two different techniques (hand spinning and electrospinning), that are able to deliver individual ceramic fibers and ceramic fiber mats. The first approach demonstrates the preparation of SiOCN fibers from a hybrid precursor of 1,3,5,7-tetramethyl-1,3,5,7-tetravinylcyclotetrasilazane (referred to as TTCSZ) and polyacrylic acid (PAA) using hand spinning. Later, SiOC fiber mats are synthesized via electrospinning from various cyclic preceramic oligomers or monomers with polyvinylpyrrolidone (PVP) as a spinning reagent. The fiber products are systematically investigated molecular structures, performances, and chemical bonding progression of the fibers at each processing stage (spinning, crosslinking, and pyrolysis). The approaches for ceramic fiber spinning and pyrolysis processes utilize cyclic siloxanes and silazanes for the first time as the ceramic precursors that are low cost and available in large quantities. The products show great potential in high-temperature applications as well as other applications such as energy storage.

Book Description
Fibre reinforced composite materials are showing sustained growth in an ever widening range of applications from food trays to spacecraft as well as contributing to resolving environmental problems, including enabling the forthcoming hydrogen economy to be realised. This second edition of Fundamentals of Fibre Reinforced Composite Materials has been fully updated throughout, providing an authoritative and modern introduction to the topic with a brief history of composite development, a review of composite applications, manufacture and markets, types of fibres and matrices used, and their properties with a detailed introduction into the computer simulation of composite behaviour. With extensive sets of sample problems accompanying each chapter, this book is ideally suited to undergraduate and graduate students of materials science, structural, mechanical, and aeronautical engineering, polymer science, metallurgy, and other courses. It will also be of use as a reference to researchers and engineers working with composite materials and material scientists in general. Features: Presents thorough discussions on composite history, composite applications and markets, types of fibres and resins used, and their respective properties Relates mathematical concepts to the structure of the material under discussion leading to the quantitative evaluation of safety factors Provides numerous sets of sample problems in each chapter
