Comparative Studies on Two Types of OSB Boards Obtained from Mixed Resinous and Fast-growing Hard Wood

Abstract

The paper aims to compare the oriented strand boards (OSBs) made in the laboratory from a mixture of softwood species to those made from hardwood species, followed by their comparison to European and industry standards. In this regard, the main properties of the panels made in the laboratory were determined, including density, absorption, and swelling in thickness, modulus of elasticity, modulus of rupture, and internal bond. The analysis of the properties of swelling (24 h) and absorption (24 h) revealed that the mixture of softwood species was slightly better thanthe hardwood one. It was also shown that the panels manufactured from the mixture of hardwood species had better mechanical properties than those made of the softwood mixture (modulus of rupture (MOR) = 43.48 N/mm2, modulus of elasticity (MOE) = 7253 N/mm, and internal bond (IB) = 1.57 N/mm2). Additionally, the comparative analysis of properties indicates that the density is highly significant in determining the MOE values of the OSBs. This will allow softwood speciestobe replaced with other species of soft and fast-growing deciduous trees such as willow, birch, and poplar in the manufacture of oriented strand boards.

Properties of dual-species bamboo-oriented strand boards bonded with phenol formaldehyde adhesive under various compression ratios

“…Several studies on OSB made from combination raw material have been conducted and showed good OSB properties (Amusant et al 2009;Arnould et al 2010;Febrianto et al 2010;Bufalino et al 2015;Suhadi et al 2018;Lunguleasa et al 2020). However, to date, information on the preparation conditions and properties of three-layer BOSBs from different bamboo species, specifically for each layer, has not been reported.…”

Engineered Wood Products as a Sustainable Construction Material: A Review

“…OSB is extensively used for wall sheathing, floor underlayment, roof cover and I-joist in both commercial and residential building. OSB also is used in furniture, reels, trailer liners and recreational vehicle floors [71][72][73].…”

Development of Lightweight Steel Framed Construction Systems for Nearly-Zero Energy Buildings

“…Since OSBs and plywood are wood-based composites, OSBs are susceptible to ignition [42], and there is a need for an additional fire protection layer. OSBs are composite multilayer boards made of wood strands with a specific shape, thickness, and adhesive strength [43,44] which are very similar to plywood, with the only significant difference being the price. This has led to OSB panels replacing plywood in the construction sector [45].…”
