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.
