速生木材的增强改性研究进展

Research Progress on Enhanced Modification of Wood From Fast-Growing Trees

速生木材因其成材快、生长周期短以及易于加工等特性,已成为我国木材加工业的主要生产原料。然而,速生木材材质疏松、强度低等缺陷严重限制其作为结构用材的应用范围,如何对其增强改性成为热点研究领域。本研究主要从速生木材自身增强、重组增强以及复合增强3个方面综述了人工速生木材增强改性的研究进展,并阐述了目前研究所面临的问题以及未来的发展趋势,以期推动速生木材增强改性的发展。

Wood from fast-growing trees has become the main raw material for the wood processing industry in China due to its fast growth and easy processing. However, its defects such as loose structure and low strength precluded the application range as structural materials. How to realize reinforcing modification has become a hot research field. In this paper, the research progress on the reinforcing modification of wood from fast-growing trees is reviewed from the aspects of wood self-enhancement, recombination enhancement and composite reinforcement. The problems faced by the current research and the future development trend are also briefly introduced.
