竹集成材及FRP材料研究进展

陈之博

摘要:竹材在建筑领域的应用很少,因为其刚度低且大小难以以控制。而竹集成材相对于普通木材可以根据需求灵活的控制它的尺寸,更具市场竞争力。首先介绍竹集成材的力学特点和其研究发展概况,指出竹集成材具有质轻而硬,耐腐蚀,抗疲劳,抗压强度表现良好的力学性能,且基本不会对环境造成负面影响。随后阐述了FRP材料的许多优点,FRP材料(全称Fiber Reinforced Polymer)是由增强纤维材料与基体材料经过缠绕,模压或拉挤等成型工艺而形成的复合材料,并且FRP材料在各个领域都有应用,也有和其他材料或技术的结合使用。最后说明了应用FRP竹集成材作为结构用材的意义。

Research progress of bamboo laminates and FRP materials Zhibo Chen

Abstract: Bamboo is rarely used in construction because of its low stiffness and difficulty in controlling its size. Compared with ordinary wood, bamboo Glulam can control its size flexibly according to the demand, so it is more competitive in the market. Firstly, the mechanical characteristics of bamboo Glulam and its research and development are introduced. It is pointed out that bamboo Glulam has light and hard quality, corrosion resistance, fatigue resistance, and good mechanical properties of compressive strength, and basically does not have negative impact on the environment. Following that, many advantages of FRP materials are described. FRP material (full name Fiber Reinforced Polymer) is a composite material formed by winding, die pressing or pultrusion of reinforcing fiber material and matrix material. And FEP materials have been used in various fields, and in combination with other materials or technologies. Finally, the significance of using FRP bamboo glue as structural material is explained.

21世纪人们逐渐认识到绿色环保,节能减排的重要性。竹子具有生长速度快、成材早、产量高等特点,我国竹资源的拥有量和品质均居世界首位随着木结构建筑在中国的日益兴起,人们对结构材的需求量逐渐增加,但我国结构用木质材料相对缺乏,竹材可替代部分木材用于建筑结构。而纤维增强复合材料(Fiber Reinforced Polymer)自1939年问世以来最早由日本和欧美等国家率先研究, 并在航空等工业领域应用较多。近几年FRP材料多用于灾后建筑物的修复或是加固,广泛的应用再加上国外较早的研究给我国在FRP材料和竹集成材领域的研究打下了坚实的基础。研究FRP材料及竹集成材的各项性能,通过中国知网、万方数据、维普数据等文献平台并在《工业建筑》等期刊上全面查阅了了有关FRP材料与竹集成材的相关文献。
