摘要

本研究乃以柳杉及木油桐速生樹種之長薄片型粒片為原料，製成長薄片型定向粒片板並探討其力學性質。其摘要如下：定向粒片板之靜曲強度高於任意排列之粒片板。但粒片定向排列對於內聚力、木螺絲釘保持力及尺寸安定性之作用不顯著。經定向排列製成之粒片板，其MaR、MOE值、內聚力、木螺絲釘保持力及其厚度膨脹均與粒片板比重呈正相關。吸水率則與粒片板比重呈負相關。

Oriented strand boards (OSB) were made from flakes of fast growing tree specieses, such as Japanese fir and Wood oil tree, which testing for physical and mechanical properties were summarized as follows: Modulus of rupture (MOR) and modulus of elasticity (MOE) of OSB were higher than the particleboard which particles random aligned, and but there was no significant difference in internal bonding strength (IB), screw-holding strength (SH) and the dimensional stability between both types particleboard. The MaR, MOE, IB , SH and thickness swelling of two tree specieses particleboards increased with board density , but the water absorption showed reverse.
