摘　　要：通过拉伸试验,研究了塑化杨木单板不同压力时的顺纹拉伸性能,分析了其与塑化压力间的关系。结果表明:塑化杨木单板的拉伸模量与塑化压力呈非线性关系;随塑化压力增大,单板的弹性模量有减小的趋势,顺纹抗拉强度呈增大趋势,但当压力增大到一定值时顺纹抗拉强度趋于稳定。Poplar veneer is an essential cell of wood-bamboo composite structure. During the course of designing-constitute of wood/bamboo composite, elastic modulus is an important factor. The property along the grain of poplar veneer of the composite of the wood/bamboo was studied through the tensile experiment, and the relationship between the tensile property and pressure was analysed. The results show that the relationship between elastic modulus and adhesive pressure is non-linear. With the increase of the adhesive pressure, elastic modulus decreases.
