摘　　要：本研究以酚醛树脂为浸渍液,杨木单板为木材试样,对经浸渍塑化处理的杨木单板进行三点弯曲试验,探索了木/竹复合层合板的组分材料——塑化杨木单板受不同压力时的顺纹弯曲弹性性能,并分析了其与塑化压力间的关系。结果表明,塑化杨木单板的静曲模量和静曲强度与塑化压力呈非线性关系。通过对杨木单板试验研究,为木材/竹材复合材料制造过程中的结构设计和生产工艺提供一定的理论依据和基本思路,并对产品的设计、组织现场生产和产品质量评估提供一定的参考。Regard PF as soaking liquid and poplar veneer as experiment species, adhesive-soaking poplar veneer were investigated by three-point bending. Study on the property along the grain of poplar veneer of the composite of the wood/bamboo through the three-point experiment, and analyzed the relationship between the bend property and pressure. The results from experiments showed that the relalionship between modulus of elasticity（MOE ）, modulus and Rupture（MOR） and adhesive pressure are non-linear. The research in this project can provide some basic grounds to the designing of the wood/bamboo laminate, organizing locale production and evaluating production quality.
