For this purpose, 80 mm long strands made of Scots pine (Pinus sylvestris L.) were bonded with phenol-formaldehyde resin at three different ratios (3, 4.5, and 6%) to produce three-layer cross-aligned OSBs. Strands used for the production of OSB panels were made up 40% of core layer and 60% of outer layers. The panels were pressed for three different press times, from 3, 5, to 7 minutes, under 0.4 MPa pressure, aiming for a target density of 0.70 g/cm3. TS, IB, MOR, and MOE properties of OSB panels were evaluated according to the standards (TSE EN 117-319-310). Results showed that MOR and MOE values were changed in the ranges 25.31 to 42.27 N/mm(2), and 2848.90 to 6545.63 N/mm(2), respectively. Also, the results showed that as adhesive ratio and pressure time increased, the TS, MOR, and MOE values increased too.eninfo:eu-repo/semantics/closedAccessOriented strand boardStrand alignmentPhenol-for maldehydePhysical propertiesMechanical propertiesArticle2124221186WOS:000291559600091Q1
