碩士 === 國立臺灣大學 === 森林學研究所 === 92 === The purpose of this study was to investigate the properties of oriented strand board by CNS 2215 standard and non-destructive tests. The features of all flakes were with crude surfaces. The flake’s aligned angle on the face layer of OSB within 0 ∘-30 ∘ accumulated to 74-92% of the total flakes. The ultrasonic velocity (V) at 0 ∘of aligned angle (V0) was the highest, decreased rapidly with increasing aligned angle. There were significant positive relationships between velocity and MOR, MOE, MOEdv, IB, SH. In drill resistance test, the PD, MD affected on properties of bending strength positively while Pdi affected on properties of bending strength negatively. All of its physical and mechanical properties met the standard as specified in CNS 2215 30-15 type and 24-10 type of particleboard.
