Bio-based materials, including those containing wood, will become increasingly important as we move to a bio-based economy. Among their many attributes, it is vitally important that these materials are renewable, sustainable with proper management and environmentally benign. Wood remains one of our most important bio-based materials. While it is an amazing material, wood still has negative attributes and drawbacks that can affect performance, including dimensional instability when wetted, vulnerability to fire and high temperatures, and susceptibility to biodeterioration. A variety of treatments have been developed to overcome these weaknesses. Among the most exciting of these treatments are nanomaterials. These materials have some exceptionally attractive properties for improving timber performance and have been the subject of intensive research over the past decade. There is a tremendous need for a single comprehensive source of information on this rapidly emerging subject with tremendous potential to enhance the performance of a variety of bio-based materials. This book contains 10 chapters, each compiled by different author(s) who are considered the top researcher(s) in their respective fields. The chapters begin with some basic background on nanomaterials and their synthesis, then explore different areas for potential applications and conclude with a review of the emerging questions about nanomaterial safety. The book is designed to provide the latest information and know-how on application and utilization of different nanomaterials to improve the properties of wood and wood-based composite panels. The contents cover some main topics in the industry including improving physical and mechanical properties, increasing resistance to biodegradation (including fungi and insects), developing wood-plastic composites (WPC), applying nanomaterials in paper and board industry, and emergence of transparent wood and radiation shielding. It also covers the use of nanomaterials to improve the performance of paints and finishes used for forest products. The book provides a single location for those interested in the field to begin.
Over the past two decades, there has been a shift in research and industrial practice, and products traditionally manufactured primarily from wood are increasingly combined with other nonwood materials of either natural or synthetic origin. Wood and other plant-based fiber is routinely combined with adhesives, polymers, and other "ingredients" to produce composite materials. Introduction to Wood and Natural Fiber Composites draws together widely scattered information concerning fundamental concepts and technical applications, essential to the manufacture of wood and natural fiber composites. The topics addressed include basic information on the chemical and physical composition of wood and other lignocellulosic materials, the behavior of these materials under thermocompression processes, fundamentals of adhesion, specific adhesive systems used to manufacture composite materials, and an overview of the industrial technologies used to manufacture major product categories. The book concludes with a chapter on the burgeoning field of natural fiber-plastic composites. Introduction to Wood and Natural Fiber Composites is a valuable resource for upper-level undergraduate students and graduate students studying forest products and wood science, as well as for practicing professionals working in operational areas of wood- and natural-fiber processing.
