1、组合材组合材宋洪丁国立嘉义大学林产科学系 教授. 组合板之定义与分类() 组合板之定义：1. 组合板：由木材粒片、木材纤维或其它木质材料，藉胶合剂经温度及压力制成板材。狭义者，包括粒片板及纤维板；广义者，包括各类木质板材之复合板。2. Composite Panel：A veneer-faced panel with a reconstituted wood core. The flakeboard core may be random or have alignment in the direction 90from the grain direction of the veneer fac

2、es.3. 人造板(wood-based panels)：木质纤维原料经机械加工分离成为各种形状的单元材料，再经组合压制成的各种板材。单元材料的形状有单板、薄木、木块、板条、木丝、刨花以及纤维等多种。制成板材的物理力学性质与木材类似。人造板主要包括胶合板、纤维板、刨花板等三大类。4. 三板：胶合板 刨花板 纤维板5. Plywood：A glued wood panel made up of relatively thin layers of veneer with the grain of adjacent layers at right angles, or of veneer in co

3、mbination with a core of lumber or of reconstituted wood.6. Particleboard：A generic term for a material mannfactured from wood particles or other ligno-cellulosic material and a synthetic resin or other suitable binder.7. Fiberboard：A broad generic term inclusive of sheet materials of widely varying

4、 densities manufactured of refined or partially refined wood (or other vegetable) fibers. Bonding agents and other materials may be added to increase strength, resistance to moisture, fire, or decay, or to improve some other property.Figure1.1 Classification of wood composition-boardsFigure1.2 Simpl
