摘要

本試驗使用厚度12mm、9mm、6mm及3mm之中密度纖維板（MDF），以集成方式膠合成厚度24mm之集成中密度纖維板，並以厚度24mm之中密度纖維板為控制組，分別探討其在木釘、方榫及橢圓榫接合強度上之差異。試驗結果顯示集成纖維板之比重及吸水厚度膨脹率等性質與控制組相比具改善效果。在T型構件之接合引拔強度方面，除橢圓榫接合外，所有集成中密度纖維板之木釘及方樺接合強度，平均約為控制組的1.4倍；而在L型構件之接合靜曲彎矩方面，則集成中密度纖維板之木釘、方樺及橢圓榫接合強度皆有明顯改善效果，平均約為控制組的1.3倍之強度。另外，當以聚醋酸乙烯乳膠、富蘭克林乳膠、粉末狀三聚氰胺尿素膠及混合膠集成時，以聚醋酸乙烯乳膠集成者顯示較低引張強度和靜曲彎矩。集成纖維板之接合強度有些接合方式相當於針葉樹，應可供為某些家具使用。

Experimental samples were laminated to form 24mm thick with board 12mm, 9mm, 6min, and 3mm medium desnity fiberboard as lamination. The withdrawal strength and maximum bending moment of dowel joint, squareend and oval-end mortise and tenon joint were then evaluated for each laminated members and compared with those of the 24mm single layer medium density fiberboard , The specific gravity and water absorption thickness swelling of the laminated medium density fiberboard were improved in most cases. Among the joint methods, the dowel joint and square-end joint of laminated MDF showed better withdarwal strength than the controlled. The average improvement could be 1.4 times of the controlled one. For maximum bending moment, the three joint methods of laminated MDF were higher than controlled. The improvement ratio was approximately 1.3. When laminated with different adhesives, the laminated MDF with PVAc showed lower tension strength and bending moment for oval-end joint. As far as the joint strength is concerned, the laminated MDF could be as strong or stronger than some conifer species. Therefore, the laminated MDF may be used in furniture.
