竹材特性研究及其进展

随着人们环境意识的日益加强以及对森林保护的重视,世界有关国家对竹材特性进行了大量的研究。文中在查阅20世纪80年代以来有关竹材特性研究资料的基础上,对竹材的解剖性质、力学性质、物理性质、化学性质、微观结构和力学性质之间的关系等研究现状进行了总结和分析,并提出了对竹材某些特性进行深入研究的若干看法。

Characteristics Research of Bamboo and Its Development

Along with the people's increasingly awareness on environmental consciousness and the importance of forest protection, scientists in bamboor elated countries have done a greatdeal of research on the charact eristics of bamboo. The development of research on physical-mechanical properties、chemical properties and anatomical characteristics of bamboo was mainly reviewed in the following aspects: density, moisture content, shrinkage and swelling, mechanical properties, chemical properties, anatomical charact eristics, relation between micro-structure and mechanical properties, biological physics and mechanicsetc. The authors suggest that research on bamboo charact eristics should focus on the microcosmic mechanics, the ultra microst ructure of bamboo fiber, the relat ionship between cell wall and density, bio-physics and mechanics, the physical-mechanics properties of bamboo in different positions, and the influence of chemical constituents such as cellulose, hemicelluloses and lignin on processing technology.
