Engineered wood. Engineered wood, also called mass timber, composite wood, human-made wood, or manufactured board, includes a range of derivative wood products which are manufactured by binding or fixing the strands, particles, fibres, or veneers or boards of wood, together with adhesives, or other methods of fixation [ 1] to form composite ...
Thermally modified wood is engineered wood that has been modified by a controlled pyrolysis process of wood being heated to (> 180 °C) in an oxygen free atmosphere. This process changes to the chemical structures of wood's cell wall components lignin , cellulose and hemicellulose which decreases its hygroscopy and thus increases dimensional ...
Plywood is a composite material manufactured from thin layers, or "plies", of wood veneer that are glued together with adjacent layers, having both glued with each other at right angle. It is an engineered wood from the family of manufactured boards, which include plywood, medium-density fibreboard (MDF), oriented strand board (OSB), and ...
Wood may also refer to other plant materials with comparable properties, and to material engineered from wood, woodchips, or fiber. Wood has been used for thousands of years for fuel , as a construction material , for making tools and weapons , furniture and paper .
Cross-laminated timber (CLT) is an engineered wood product that is gaining popularity in the construction industry due to its numerous advantages, such as sustainability, cost-effectiveness, and ease of construction. Mechanical properties, particularly compressive strength, are key factors to consider when designing and constructing CLT panels.
Wood science [1] is the scientific field which predominantly studies and investigates elements associated with the formation, the physical and chemical composition, and the macro- and microstructure of wood as a bio-based and lignocellulosic material. Wood science additionally delves into the biological, chemical, physical, and mechanical ...
Medium-density fibreboard. Medium-density fibreboard ( MDF) is an engineered wood product made by breaking down hardwood or softwood residuals into wood fibre, often in a defibrator, combining it with wax and a resin binder, and forming it into panels by applying high temperature and pressure. [ 1] MDF is generally denser than plywood.
Parallel-strand lumber ( PSL) is a form of engineered wood made from parallel wood strands bonded together with adhesive. It is used for beams, headers, columns, and posts, among other uses. The strands in PSL are clipped veneer elements having a least dimension of not more than inch (6.4 mm) and an average length of at least 300 times this ...
