Abstract
A novel process has been developed for manufacturing poplar wood scrimber boards (SBs), in the course of which thick veneers are produced first and then the oriented wood fiber mats (OWFMs) are fabricated in a pilot scale fluffing machine. A low molecular weight phenol-formaldehyde (PF) resin is applied for gluing and the cold-prepressing of the mats is followed by hot-curing between 120 and 130°C for 12 h. The mechanical properties and dimensional stability of the SBOWFMs were measured. The new process resulted in significantly better mechanical properties of SBOWFMs compared with those of raw wood and other poplar wood-based composites. All data including the dimensional stability of SBOWFMs increased with increasing density.
