Finding alternative uses for small diameter raw materials is a critical problem throughout the United States. Insufficient markets for small diameter, southern yellow pine (Pinus spp.) trees from first plantation thinnings are impacting silvicultural practices on millions of acres of land. In western states, the lack of markets for small diameter ponderosa pine (Pinus ponderosa) and lodgepole pine (Pinus contorta) creates multiple problems in terms of excess material in the forest. This excess material enhances fire potential and reduces land management practices. This research deals with a new structural composite from small diameter raw logs using a technology called steampressed scrim lumber (SPSL). Mechanical and physical properties were performed and evaluated for each species. This research was conducted to evaluate these properties and to determine the suitability for commercialization.

Wood is a gift from nature. It is a sustainable and renewable bio-composite material that possesses a natural ability to mitigate carbon dioxide. However, due to deforestation and climate change, it has become necessary to develop alternative building and construction materials. Engineered wood products (EWPs) such as parallel strand lumber, laminated veneer lumber, and cross-laminated timber are promising substitutions for conventional lumber products. This book presents a comprehensive overview of EWPs, including information on their classification, design, synthesis, properties, and more. It is divided into two sections: “General Overviews and Applications of EWPs” and “Recent Research and Development of EWPs”. The book is a valuable reference for manufacturers, engineers, architects, builders, researchers, and students in the field of construction.

Wood as an engineering material can be technically defined "as a hygroscopic, orthotropic, biological, and permeable material having extreme chemical diversity and physical complexity with structures, that vary extensively in their shape, size, properties and function". Therefore, using wood to its best advantage and most efficiency in engineering and technology applications, specific characteristics or chemical, physical and mechanical properties must be considered. This book aims to provide the research and review studies on wood and wood products with special emphasis in machining aspects. The present research book can be used for final undergraduate engineering course (for example, wood, materials, mechanical, manufacturing, etc) or as a subject on wood and wood products at the postgraduate level. Also, this book can serve as a useful reference for academics, wood researchers, mechanical, manufacturing and materials engineers, professionals in areas related to the wood and wood products.

Nondestructive evaluation procedures are now widely used in the forest products industry. These procedures rely upon nondestructive tests to evaluate important physical and mechanical properties of wood-based materials and began with fundamental research during and after World War II. An important outcome was the evolution of machinery and process for grading lumber and veneer. A dedicated group of scientists and engineers conducted and adapted this research for industrial use and developed equipment to make accurate measurements of wood properties in a production setting. One of those engineers, Dr. Friend K. Bechtel, spent over 40 years developing modern testing equipment for use by the forest products industry. Among his significant contributions to the nondestructive testing field is his fundamental analytical work. Most of his design work began with a thorough evaluation of a test method, starting with underlying physical and mechanical principles. As an industrial research engineer, he focused on designing quality equipment that would provide accurate information to manufacturers and users of wood products. This publication describes some of his work in context with that of others, some previously reviewed and published and some not. It begins with a history of the industrial development of the machine stress rating lumber grading process. It then summarizes analytical work that delves into the effects that nonhomogeneities frequently found in wood products have on their mechanical properties.

The purpose of this monograph is to characterize and describe the quality of machined wood surfaces, whereas particular attention is given to the utility and to aesthetical values in product design. The approach employed by the authors involves an introductory overview and is then organized in three parts: first, the book deals with factors influencing surface stability, the second part describes the color and gloss properties of wood surfaces with many practical applications, and the third part covers roughness properties of surfaces related to machining. This is a highly informative and carefully presented book, providing valuable insight for both research experts and practitioners with an interest in machined wood surfaces.
