This book was released on 2016-03-21 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are many types of structural composite lumber (SCLs) commercially available now, and some new SCLs may come on stream in the near future. The SCLs that have prevailed in North America can be exemplified by glue-laminated timber (glulam), laminated veneer lumber (LVL), parallel strand lumber (PSL), and oriented strand lumber (OSL) or laminated strand lumber (LSL). Of these, glulam, LVL, and PSL are in mature stages, while OSL and LSL are still in their infant stages. The growing market potential of LSL is high because the LSL manufacturing technology can be further improved, particularly as its strand orientator (aka orienter) is substantially improved. Consequently, the production cost of LSL can be reduced and product properties can be enhanced. In general, different types of SCLs can be engineered to meet structural performance. The manufacture of SCL relies heavily on experience rather than the laws of science. Unfortunately, some experiences are biased because they are drawn from the manipulation of one or two variables without consideration of possible interactions with other factors. As a result, many SCL manufacturers have experienced start-up and growing pains in trying to engineer and produce low-cost products for specific applications while maximizing their profit. Nevertheless, the SCL industry has cumulatively amassed a lot of experiences and knowledge about manufacturing quality SCL. These experiences and knowledge are transferable, and any new SCL manufacturers can learn from these experiences and knowledge so that they need not make similar mistakes and go through similar start-up and growing pains as established manufacturers have already experienced. Nearly any new mill will have the same, or similar, equipment and processes as are used in existing mills manufacturing the same type of SCL. New manufacturers often learn from the experiences of the existing mills, both good and bad. However, it is essential to avoid experiencing the same problems encountered by the established mills. Otherwise, new SCL mills will fail to have a competitive edge over existing mills. One of my objectives in writing this book is to provide comprehensive information on the basics of SCL manufacturing. Another objective is to share my knowledge about SCL, experiences in research and development of SCLs, and practical experiences in the field. Hopefully, this book will help new manufacturers not make the same mistakes as established manufacturers, as well as assist established manufacturers with getting rid of bad practices. Although most of the basic information and knowledge of manufacturing different SCLs in this book can be found in existing published reports and books, this is probably the first book focused on SCL that covers the gamut of SCL manufacturing issues, including raw materials, equipment, processes, manufacturing parameters, challenges, and solutions for various kinds of SCL manufacturers. I have also attempted to highlight the important avenues necessary to make quality products at minimal production costs, and given my own thoughts of further improvement in product quality, processes and equipment.

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.
Download or read book Delamination in Wood Wood Products and Wood Based Composites written by Voichita Bucur and published by Springer Science & Business Media. This book was released on 2010-11-02 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the last quarter century, delamination has come to mean more than just a failure in adhesion between layers of bonded composite plies that might affect their load-bearing capacity. Ever-increasing computer power has meant that we can now detect and analyze delamination between, for example, cell walls in solid wood. This fast-moving and critically important field of study is covered in a book that provides everyone from manufacturers to research scientists the state of the art in wood delamination studies. Divided into three sections, the book first details the general aspects of the subject, from basic information including terminology, to the theoretical basis for the evaluation of delamination. A settled terminology in this subject area is a first key goal of the book, as the terms which describe delamination in wood and wood-based composites are numerous and often confusing. The second section examines different and highly specialized methods for delamination detection such as confocal laser scanning microscopy, light microscopy, scanning electron microscopy and ultrasonics. Ways in which NDE (non-destructive evaluation) can be employed to detect and locate defects are also covered. The book’s final section focuses on the practical aspects of this defect in a wide range of wood products covering the spectrum from trees, logs, laminated panels and glued laminated timbers to parquet floors. Intended as a primary reference, this book covers everything from the microscopic, anatomical level of delamination within solid wood sections to an examination of the interface of wood and its surface coatings. It provides readers with the perspective of industry as well as laboratory and is thus a highly practical sourcebook for wood engineers working in manufacturing as well as a comprehensively referenced text for materials scientists wrestling with the theory underlying the subject.
