摘要

本研究採用市售12 mm厚度之粒片板及中密度纖維板與市售6 mm厚度之高爐礦渣板及粒片水泥板，按照製板的結構配置條件，利用砂光機分別砂除至所需之不同厚度，再藉醇溶性酚甲醛樹脂膠合劑以180°C溫度、10kgf/cm^2初期壓力熱壓製作12 mm厚度之木質複合板，探討各成板之理學及力學性質。主要試驗結果歸納如次：1.表層採高爐礦渣板或粒片水泥板與粒片板及纖維板複合製得之複合板性質，主要受到表層材料特性所影響；概言之，表層採用高爐礦渣板複合者之質量較輕，吸水厚度膨脹率及吸濕率較低，而表層採用粒片水泥板複合者則其有較優良的靜曲破壞強度、靜曲彈性係數、內聚強度及木螺絲保持力等性質。2.內層採高爐礦渣板或粒片水泥板與粒片板及纖維板複合製得之複合板性質，受到內層材料性質之影響較小，其中僅以粒片水泥板為內層製板之木螺絲保持力隨內層複合層厚度之增加而增大較為顯著之外，其餘性質仍低於未複合處理之粒片板或纖維板。3.基於木質複合板用途考量，採用表層高爐礦渣板或粒片水泥板之複合製板，其製板質量較高爐礦渣板或粒片水泥板輕且吸水厚度膨脹率及吸水率較低，力學性質亦提高很多不失為理想的複合方式。

The purpose of this study was to evaluate the physical & mechanical properties of woodbased composite boards made from particleboard& fiberboard in combination with furnace-dregs board or woodparticle-cement board. In order to investigate the influence of the face or core layer thickness of furnace-dregs board or woodparticle-cement board on the composite boards. In this experimental the total thickness of the board assigned was at approximately 12mm. The 12mm thickness of commercial particleboard & fiberboard and the 6mm thickness of furnace-dregs board & woodparticle-cement board were used for preparation of the composite boards, and the thickness of boards were controlled by sanding operation. The alcoholic soluble type of PF resin adhesives was used as bonding agent. The combined pieces were pressed at 180°C under an initial pressure of 10kgf/cm^2 for the curing. The results indicated as follows: 1. The performance of woodbased composite boards, in combination the face layer with furnace-dregs board or woodparticle-cement board, were influenced greatly on the properties of the face layer materials. In the general, the board of combined with furnace-dregs board is reduced weight, absorption and thickness swelling in water , and is inferior in module of rupture , module of elasticity, internal bonding and wood screw holding capacity etc.. 2. The performance of woodbased composite boards, in combination the core layer with furnace-dregs board or woodparticle-cement board, were less influenced on the properties of the core layer materials. With the exception of the wood screw holding capacity, while the board of combined of woodparticle cement board core improved with increasing the layer thickness, the other properties are inferior to those of the control board. 3. The composite boards as the face layer, the performance of reduced weight, lower absorption and thickness swelling in water, and increased mechanical properties, were surperior to furnace-dregs board or woodparticle-cement board. Based on the uses of woodbased composite boards, the appropriate fabrication can be actived by applying this composite boards was used.
