Abstract ：Curved wood furniture has its own characteristics which have been increasingly appreciated by customers. Now there are some obvious defaults in the domestic way to make curved product such as the waste of material during the production and environment pollution which caused by chemical process. In the paper, physical method to soften wood samples has been studied and the softening temperature, softening press and softening time which have influence on the effect of curved samples have been analyzed to acquire the optimum technological parameters. The paper can be served as reference to the theoretical basis on producing cured wooden furniture in the factories.
Adopt the hot water to soften wood that can be realized easily on the industry, review the influence of changing technology conditions on the property of longitudinal tension and compression. The experiment design takes the water temperature, heat preserving time and cooling time as the influence factors. Adopt the optimizing design to find out the best result, the thesis studies the bend and recovery of poplar after compressed.
Key words：Poplar; Hydrothermal pretreatment; Bend
