Cellular Metals and Polymers


Book Description

This collection constitutes an essential sourcebook for researchers, producers and users seeking technical information on materials with foam-like structures.The collection is unique, in that it brings together people from the fields of metals and polymers. Both material types derive their advantageous properties from a cellular structure. These properties include: low weight, high specific stiffness and strength, excellent energy absorption capacity, as well as damping and insulation properties. On the other hand, the processing of metals is far more difficult due to the higher temperatures involved. Another important factor is the faster decay of metal foam structures, at the end of the foaming process, because of their combination of high surface tension and low viscosity. The differences in foamability, between metals and polymers, explain why cellular plastics have been widely used for some time whereas cellular metals have only recently found their first applications. The present volume expertly reviews the known scientific results in these fields; particularly with regard to the understanding of foam processing (e.g. mechanisms of stabilization) as well as foam properties (e.g. the material's response to fatigue and crash situations).This collection constitutes an essential sourcebook for researchers, producers and users seeking technical information on materials with foam-like structures. The 63 papers of this proceedings were first presented at the Symposium on Cellular Metals and Polymers, sponsored by the Deutsche Forschungsgemeinschaft, in October 2004, in Fürth, Germany. Also included are reports from the DFG program on Cellular Metals. Keynote talks were given on topics that include an overview of the mechanical properties of foams and periodic lattice materials, physics of polymer foams, and the role of rheology in foaming polymers. The papers are grouped into sections, including processes of metal foams, properties of metal foams, particle foams and simulation, component fabrication and application of metal foams, and commercial applications and products of polymer foams. The volume is illustrated with b&w plates, and contains an author.




Metal Foams: A Design Guide


Book Description

Metal foams are at the forefront of technological development for the automotive, aerospace, and other weight-dependent industries. They are formed by various methods, but the key facet of their manufacture is the inclusion of air or other gaseous pockets in the metal structure. The fact that gas pockets are present in their structure provides an obvious weight advantage over traditionally cast or machined solid metal components. The unique structure of metal foams also opens up more opportunities to improve on more complex methods of producing parts with space inclusions such as sand-casting. This guide provides information on the advantages metal foams possess, and the applications for which they may prove suitable. - Offers a concise description of metal foams, their manufacture, and their advantages in industry - Provides engineers with answers to pertinent questions surrounding metal foams - Satisfies a major need in the market for information on the properties, performance, and applications of these materials




Cellular Solids


Book Description

In this new edition of their classic work on Cellular Solids, the authors have brought the book completely up to date, including new work on processing of metallic and ceramic foams and on the mechanical, electrical and acoustic properties of cellular solids. Data for commercially available foams are presented on material property charts; two new case studies show how the charts are used for selection of foams in engineering design. Over 150 references appearing in the literature since the publication of the first edition are cited. The text summarises current understanding of the structure and mechanical behaviour of cellular materials, and the ways in which they can be exploited in engineering design. Cellular solids include engineering honeycombs and foams (which can now be made from polymers, metals, ceramics and composites) as well as natural materials, such as wood, cork and cancellous bone.

Cellular Ceramics


Book Description

Cellular ceramics are a specific class of porous materials which includes among others foams, honeycombs, connected fibers, robocast structures and assembled hollow spheres. Because of their particular structure, cellular ceramics display a wide variety of specific properties which make them indispensable for various engineering applications. An increasing number of patents, scientific literature and international conferences devoted to cellular materials testifies to a rapidly growing interest of the technical community in this topic. New applications for cellular ceramics are constantly being put under development. The book, authored by leading experts in this emerging field, gives an overview of the main aspects related to the processing of diverse cellular ceramic structures, methods of structural and properties characterisation and well established industrial, novel and potential applications. It is an introduction to newcomers in this research area and allows students to obtain an in-depth knowledge of basic and practical aspects of this fascinating class of advanced materials.




Materials Processing


Book Description

Materials Processing: A Unified Approach to Processing of Metals, Ceramics and Polymers, Second Edition is the first textbook to bring the fundamental concepts of materials processing together in a unified approach that highlights the overlap in scientific and engineering principles. It teaches students the key principles involved in the processing of engineering materials, specifically metals, ceramics and polymers, from starting or raw materials through to the final functional forms. Its self-contained approach is based on the state of matter most central to the shaping of the material: melt, solid, powder, dispersion and solution, and vapor. With this approach, students learn processing fundamentals and appreciate the similarities and differences between the materials classes. This fully updated edition includes expanded coverage on additive manufacturing, as well as adding a new section on machining. The organization has been modified and a greater emphasis has been placed on the fundamentals of processing and manufacturing methods. This book can be utilized by upper-level undergraduates and beginning graduate students in Materials Science and Engineering who are already schooled in the structure and properties of metals, ceramics and polymers, and are ready to apply their knowledge to materials processing. It will also appeal to students from other engineering disciplines who have completed an introductory materials science and engineering course. - Includes comprehensive coverage on the fundamental concepts of materials processing - Provides coverage of metals, ceramics, and polymers in one text - Presents examples of both standard and newer additive manufacturing methods throughout - Gives students an overview on the methods that they will likely encounter in their careers




Voids in Materials


Book Description

All materials have voids in them, at some scale. Sometimes the voids are ignored, sometimes they are taken into account, and other times they are the focal point of the research. Voids in Materials: From Unavoidable Defects to Designed Cellular Materials takes due notice of all these occurrences, whether designed or unavoidable defects. We define, categorize, and characterize the voids (or empty spaces in materials) and we analyze the effects they have on material properties. This second edition is an updated and expanded central reference for voids in materials and covers all types of voids, intrinsic and intentional, and stochastic and nonstochastic, and the processes and conditions that are needed to create them and is a valuable resource to students in the areas of mechanical engineering, chemical engineering, materials science and engineering, physics, and chemistry, as well as scientists, researchers, and engineers in industry. - the effect of voids in materials; from low volume fraction defects and free volume in polymer networks to high void volume fraction foams and aerogels - how and why voids are introduced into materials across the length scales - biomaterial design used in vivo for soft, hard, and nerve tissue scaffolds - metallic and geopolymeric foams - additive manufacturing technologies used to tailor regularity (R) in the cell structure - stochastic, nonstochastic, and Voronoi foams - the latest techniques for characterizing voids - new chapters, covering the Kirkendall effect to create hollow and porous structures, and nanometer scale voids: nanotubes, zeolites, organic frameworks, and nanoporous noble metals
