藤蔓植物于GFRP棒构件上之兼容性实验研究

The Compatibility Experimental Studies on the Vines and GFRP Bars

摘要:

本文系将藤蔓植物生长攀附之支撑物，以具备耐腐蚀性与耐候性佳等特性的玻璃纤维强化高分子复合材料(Glass Fiber Reinforced Plastic, GFRP)，进行施作为藤蔓植物生长攀附于GFRP棒构件之植物兼容性实验。本实验方法系以GFRP螺纹棒与GFRP光滑棒2种构件，进行表面不加工、涂布油漆与环氧树脂(Epoxy)，外加竹竿构件共施作成7种实验构件，与炮仗花与薜荔2种藤蔓植物搭配成14种组合，每种组合为3盆共42盆植栽试体进行实验。本实验藉由每周一次纪录藤蔓植物的生长高度、计算生长速率以及实验试体拍照观察，利用排斥性、攀附性与美观性将藤蔓植物与不同表面GFRP棒构件间进行比较。实验结果显示，应用FRP复合材料于植生壁面绿化系统做为支撑结构材，将对于发展植生壁面绿化技术能有所帮助。

Abstract: In this paper, the application of anti-corrosion and weather resistant glass fiber reinforced plastic (GFRP) composite members to replace similar green facades made of metal materials is presented. Experiment was conducted on the plant-compatibility of the GFRP components. In the plant-compatibility experiments, 2 species of vines—Pyrostegia venusta and Ficus pumila—were supported by two kinds of GFRP rods (threaded and smooth rods). Both kinds of the GFRP rods were then divided into three groups depending on the coating applied (i.e. epoxy coating, paint coating or no coating) and bamboo rods, composed of 7 kinds of experiments member, which mixed into 14 kinds of combinations with the 2 species of vines. 3 plant pots were allocated making it a total of 42 specimens in the experiment. With a weekly record of the growth of vines height, growth rate calculations and experimental observation of specimens photographed, the text compared vines with different surfaces between components of the GFRP rods through exclusion, climb performance and aesthetics. From the experimental results, the application of FRP composites in vegetation greening system as a support structure material for Taiwan’s development of the vegetation greening technology can be useful.
