Advances in Process Modeling of Wood Composites
Introduction From a material structural view point, wood composites can be classified into two general product types: veneer-based and strand-based products. The first category of product, which includes plywood and laminated veneer lumber (LVL), are made of veneers bonded together with continuous glue lines. The structure is simple and organized. As a result, the product is generally lighter and requires little (less than 10%) densification. In comparison, the strand-based products, which represents a broad basis of products such as oriented strand board (OSB), particleboard, medium density board (MDF), oriented strand lumber (OSL) and ParallamTM, are much more complex in structure. The constituent elements (e.g. strands, particles and fibres) are discontinuous, resulting in highly porous and random spatial structure in mats. As such, a high degree of densification (usually 40-60%) is required to achieve sufficient bonding. These products are generally much heavier and lower in volumetric recovery. The focus of our studies has been on the strand-based products, as their structure and properties arc less known, and more importantly, they form a very broad and important class of wood composites.
