Key Engineering Materials
High performance materials are needed in many thermomechanical applications, such as advanced jet engines or gas turbines, thermal protection of space planes, thermal engineering and nuclear fusion. Ceramic-matrix composites, reinforced with long fibers, are expected to be the most promising candidates for such applications. However, several key problems will have to be solved in the near future. These problems include, above all, the development of a superior thermomechanical performance and oxidation resistance for ceramic fibers and composites, highly efficient protection against corrosion, better fiber/matrix interface design and performance, and cost effective processing.
A total of 147 peer-reviewed papers were presented during EnCera' 98. The topics covered included: "Modeling of Microstructural Evolution", "Novel Processing", "Advanced Oxide Ceramics", "Advanced Non-oxide Ceramics", "Particulate, Platelet and Whisker Reinforced Composites", "Nanostructured Ceramics and Nanocomposites", "Synergy Ceramics", "Fracture, Deformation and Mechanical Reliability", "Advanced Refractories", and "Joining, FGM and Applications" .
Ceramics have long been recognized as one of the key materials for the 21st century because of their various unique properties which cannot be duplicated by any other existing material.
Electroceramics have long furthered the development of electronics, and underpin modern-day high-technology. The development of electroceramics in Japan has been especially marked: many new electroceramics such as ferrites, varistors and sensors, as well as superior manufacturing technologies have been the result.
This process-oriented book focuses on the basic principles of composite fabrication. Upon studying these processes, one is immediately struck by the diversity of ideas and techniques. In some cases, these have been borrowed from other technologies and were designed for use with quite different materials. In other cases some very clever new means have been developed which take account of the characteristics of metals and ceramics and the higher temperatures which are typically involved in their processing.
Sol-gel technology is an important route for the fabrication of inorganic and inorganic-organic composite materials. As is typical of chemical synthesis routes, a wide range of parameters can be used to tailor the product.
This 2-vol. set covers a broad range of areas related to the fracture of materials, including fracture mechanics, dynamic fracture, fatigue, creep, environmental effects, damage mechanics, analytical and computational mechanics, reliability and failure analysis, and materials behavior.
Several things have changed in the world of composites in recent years. While many industries have reverted to metals for motor car bodies, composites have found new openings in areas such as civil engineering, particularly because they offer a simple and rapid means of restoring damaged structures. Nevertheless, the main obstacle to their widespread use in a variety of promising fields, such as machine construction, continues to be the difficulty of treating concepts such as heterogeneity and anisotropy.
