wood-based composite (WBC) are mainly manufactured for the following purposes, often simultaneously: (i) to effectively use small-diameter assortments, low-grade timber, and forest residues; (ii) to limit the amount of wood or other materials towards reducing the final costs or in case such components have limited availability; (iii) to obtain end products with improved properties and uniformity compared to those of their components; (iv) to obtain products whose performance fulfills ad hoc requirements
The European Forest Strategy (EUFS) states that “[ . . . ] the most important role of wood products is to help turn the construction sector from a source of greenhouse gas emissions into a carbon sink.”. This represents a great opportunity for WBCs, as they are widely used in construction, for instance as thermoinsulating partitions, structural components, furniture elements, etc
Summary
The products described so far have, the common denominator of all being manufactured by means of a primary processing that reduces (by sawing, peeling, chipping, defibering, etc.) the wooden raw material in unitary elements of different size (respectively, sawn timber, veneers, particles, fibers, etc.) that are, after drying, reaggregated by bonding and pressing [13] In this regard, a stricter definition of WBCs considers only those obtained by bonding together two or more of the above components in a secondary production process. A stricter definition of WBCs considers only those obtained by bonding together two or more of the above components in a secondary production process This is the case of the sandwich structures in which the external skins are made of a wood-based panel (e.g., plywood) glued to an inner core of materials that usually are different than wood. Future” considers the WBCs in their wider interpretation but with particular attention to modern and new solutions
