增强型单板层积材研究进展

用人工林木材制造增强型单板层积材替代优质木材，具有良好的应用前景。分别从制造工艺、单板性能、增强方式等方面对国内外增强型单板层积材的研究进展进行了综述。结果表明，制造工艺朝着自动化、连续化方向发展；单板性能与产品性能息息相关；增强方式有单板改性增强、树脂浸渍单板增强、竹材增强、不同树种组合增强、纤维复合材料增强。并针对我国现状，提出若干建议。

Progress on Reinforced Laminated Veneer Lumber

The increasing shortage of forest resources results in the lack of wood supply in China. Thus, reinforced laminated veneer lumber (LVL) made from fast-growing wood, in place of natural wood, has broad application prospects. In this paper, the manufacturing, veneer properties, and techniques of reinforced LVL were reviewed. It was concluded that the manufacture of LVL is developing towards continuum and automatization. The properties of LVL are closely related to the mechanical performance of the final products. The techniques of making LVL include veneer modification, resin impregnation, bamboo reinforcement and fiber reinforcement. Finally some suggestions were proposed.
