For the manufacturing technique and utilization of traditional plywood or laminated veneer lumber with difficulties of plate deformation, warping and cracking, a novel thick veneer board prepared by 4-10 mm thick veneer as the basic unit is developing. Particularly, the super thick veneer as the core plate played an important role in manufacture thick veneer board. Thus, internal stress of release was vital for improving the properties of super thick veneer (ST veneer) obtained from poplar. In this study, we discussed the performance and preparation parameters of ST veneer including time, temperature, pressure and moisture content, which affected the elasticity behavior and improve the surface properties. Compression ratio (CR), springback ratio (SR) and bending height (BH) after springback were determined. Both compression and relicense ratio have been remarkably affected according to chance of flattening pressure and time. Moisture content and temperature have significant influence on bending height. The roughness of thick veneer decreased with increasing temperature and time whether cross or parallel to grain. The contact angles decreased with increasing pressing temperature resulting in better wettability. XPS results showed that temperature played a significant role in chemical changes of veneer surface. It was demonstrated that thermal-press treatment could improve the properties of ST veneer, and appropriate parameters could develop its functional utilization in the field of composite materials.
