Download or read book Timber written by H E Desch and published by CRC Press. This book was released on 1996-06-13 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: For nearly 60 years, Timber: Structure, Properties, Conversion, and Use has been the authoritative text on timber technology. Now in its seventh edition, this book remains a vital resource, providing accurate, comprehensive, and fact-driven information for students and professionals in the field. From basic coverage of timber structure, properties, processing, and utilization, to more in-depth scientific investigations, this book covers all the issues and topics of concern to readers with a wide range of levels of sophistication. Timber technology has not stood still since the last revision; Timber: Structure, Properties, Conversion, and Use has kept the pace, exploring such high-tech topics as computer-aided wood identification and log conversion, radio frequency drying of wood, enhancement of wood with plastics, application of preservatives with high-pressure vacuum systems, and the development and application of flame-retardant solutions. Other timely updates include enlarging the chapter on mechanical performance to cover elastic behavior, toughness, and the use of structural-sized timber for strength tests. The chapter on board materials has also been extensively updated and enlarged to include information on new boards and structural composites that have emerged since the last edition. One of the most important strengths of Timber: Structure, Properties, Conversion, and Use is its versatility as a reference for timber professionals while remaining approachable to students in the field. Evidence of the book?s comprehensiveness and versatility becomes clear as it teaches readers about such wide-ranging topics as: identification and nomenclature of timbers variability in cellular features between species principal chemical constituents in timber structural variability caused by natural defects such as bark pockets, resin streaks, and brittleheart determination of density and moisture content in timber thermal and acoustic properties of wood conversion equipment such as circular saws, band saws, frame saws, and chipper canters health and safety issues in the industry adhesives, metal connectors, and joint design forest and millyard pests application of preservatives and finishes From basic identification and timber nomenclature to methods of sap displacement and tests of electrical conductivity, Timber: Structure, Properties, Conversion, and Use covers it all. And while it is no longer possible for any one individual to write authoritatively on every aspect of timber technology, embracing as it does structure, properties, conversion, utilization, and behavior in service, J. M. Dinwoodie has gathered expert opinions and expanded on original author H. E. Desch?s approach and vision to continue to provide the authoritative text on timber technology.

Book excerpt: Wood-based materials are CO2-neutral, renewable, and considered to be environmentally friendly. The huge variety of wood species and wood-based composites allows a wide scope of creative and esthetic alternatives to materials with higher environmental impacts during production, use and disposal. Quality of wood is influenced by the genetic and environmental factors. One of the emerging uses of wood are building and construction applications. Modern building and construction practices would not be possible without use of wood or wood-based composites. The use of composites enables using wood of lower quality for the production of materials with engineered properties for specific target applications. Even more, the utilization of such reinforcing particles as carbon nanotubes and nanocellulose enables development of a new generation of composites with even better properties. The positive aspect of decomposability of waste wood can turn into the opposite when wood or wood-based materials are exposed to weathering, moisture oscillations, different discolorations, and degrading organisms. Protective measures are therefore unavoidable for many outdoor applications. Resistance of wood against different aging factors is always a combined effect of toxic or inhibiting ingredients on the one hand, and of structural, anatomical, or chemical ways of excluding moisture on the other.

Book excerpt: Since the sixth edition of this classic text/reference was published in 1981, there have been so many developments in the field that the new seventh edition represents an almost total rewrite of the subject matter. The opportunity has been taken to rearrange the structure and broaden the scope to cover areas of conversion, machining and the application of paints and finishes; the format has also been enlarged to improve readability. Part 1 contains chapters that deal with the structure of wood at the gross, cellular and molecular levels; variability is also covered. Part 2 has five chapters on the properties of wood, with special coverage of elastic behaviour, toughness and the use of structural-sized timber for strength tests. Part 3 on processing has material on several new areas not covered in earlier editions of the book; for example, log conversion, seasoning, and the machining of wood and board. The discussion of grading and grade stresses is fully updated. Part 4 on utilisation examines the latest techniques and standards for the manufacture of wood products. Part 5 examines all aspects of timber in service, including protection and preservation. The book will appeal to a wide readership, both as a student text and reference. Students of wood science and forestry at undergraduate and equivalent level will find it of special value. All institutions with courses in the built environment will wish to make the book available as a reference source.

Available in PDF, EPUB and Kindle. Book excerpt: Wood is the most versatile raw material available to man. It isburned as fuel, shaped into utensils, used as a structuralengineering material, converted into fibres for paper production,and put to newer uses as a source of industrial chemicals. Its quality results largely from the chemical and physicalstructure of the cell walls of its component fibres, which can bemodified in nature as the tree responds to physical environmentalstresses. Internal stresses can accumulate, which are releasedcatastrophically when the tree is felled, often rendering thetimber useless. The quality of timber as an engineering materialalso depends on the structure of the wood and the way in which ithas developed in the living tree. Tree improvement for quality cannot be carried out without anunderstanding of the biological basis underlying wood formation andstructure. This volume brings together the viewpoints of bothbiologists and physical scientists, covering the spectrum from theformation of wood to its structure and properties, and relatingthese properties to industrial use. This is a volume for researchers and professionals in plantphysiology, molecular biology and biochemistry.

Available in PDF, EPUB and Kindle. Book excerpt: The degradable nature of high-performance, wood-based materials is an attractive advantage when considering environmental factors such as sustainability, recycling, and energy/resource conservation. The Handbook of Wood Chemistry and Wood Composites provides an excellent guide to the latest concepts and technologies in wood chemistry and bio-based composites. The book analyzes the chemical composition and physical properties of wood cellulose and its response to natural processes of degradation. It describes safe and effective chemical modifications to strengthen wood against biological, chemical, and mechanical degradation without using toxic, leachable, or corrosive chemicals. Expert researchers provide insightful analyses of the types of chemical modifications applied to polymer cell walls in wood, emphasizing the mechanisms of reaction involved and resulting changes in performance properties. These include modifications that increase water repellency, fire retardancy, and resistance to ultraviolet light, heat, moisture, mold, and other biological organisms. The text also explores modifications that increase mechanical strength, such as lumen fill, monomer polymer penetration, and plasticization. The Handbook of Wood Chemistry and Wood Composites concludes with the latest applications, such as adhesives, geotextiles, and sorbents, and future trends in the use of wood-based composites in terms of sustainable agriculture, biodegradability and recycling, and economics. Incorporating over 30 years of teaching experience, the esteemed editor of this handbook is well-attuned to educational demands as well as industry standards and research trends.

Book excerpt: "I have the honor to transmit herewith for publication a brief but comprehensive discussion of the characteristics and properties of wood in general and of our American timbers in particular, which it is hoped may be useful to engineers, architects, carpenters, lumbermen, and all wood workers. The paper was prepared by Mr. Filibert Roth, in charge of the investigations in timber physics. Although much of the information contained in this bulletin exists in the experience of practical woodworkers and in books in other languages, it has never before been published in English is systematic and accessible form and with special application to American timbers. Such a publication can not, of course, exhaust any part of this great subject. It is desired that it may be followed by a more elaborate treatise when additional knowledge has been gained through the investigations now in progress. The information it contains is largely based on actual experiment and scientific observation, and will, it is hoped, not only explain the experiences of the practical worker with his material, but will remove erroneous notions, and thus aid in improving the practice and lead to a more rational use of our forest resources."--Letter of Transmittal, Page [i].

Download or read book Structure and Properties of Wood Polymer Composites WPC written by Alexander Askadskii and published by Cambridge Scholars Publishing. This book was released on 2019-03-05 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: At present, the use of polymer composites filled with wood (WPC) is becoming increasingly popular. In particular, flooring of terraced premises, siding, decorative fences, fence systems, steps, universal profiles, among others are made from WPC. In 1977, the first enterprise for the production of WPC appeared in Sweden. The first experience was not very successful – the demand turned out to be low, and the wear of technological equipment was very high. Therefore, developments in this field were resumed only in the 1990s and continue to this day. This book describes the basic physical and mechanical properties of modern WPC, such as tensile and compression strength, and hardness. Also, the influence of climatic factors on the performance properties of products from WPC is described, while the thermal and rheological properties of WPC materials are considered, which directly affect the consumer characteristics of the products. The book contains theoretical developments related to the prediction of the mechanical and thermal properties of polymers and composites. The Van der Waals volume and the energy of the intermolecular interaction are estimated. This book will be of interest to representatives of the WPC market, designers, and architects, as well as technology engineers, students and post-graduate students of higher educational institutions in the fields of chemistry and physics of composite polymer materials.
