摘要

本研究利用玻璃纖維強化高分子複合材料(Glass Fiber Reinforced Plastic, GFRP)質量輕、強度高、耐腐蝕、耐候性佳以及優異的隔熱與絕緣等特性，應用GFRP構件於「植生壁面綠化系統」，以取代傳統植生立面結構之金屬材料。本研究係分別進行GFRP構件生物相容性實驗與GFRP構件力學實驗。GFRP構件生物相容性實驗係以炮仗花與薜荔2種藤蔓植物，針對以GFRP螺桿圓棒與GFRP光滑圓棒2種構件進行表面不加工、塗布油漆與塗布環氧樹脂(Epoxy)，共有12種搭配組合，其每組3盆共36盆植栽試體進行實驗。GFRP構件力學實驗包含GFRP構件三點抗彎載重實驗、GFRP構件化學接合拉力實驗共3組試體、GFRP構件物理接合拉力實驗共3組試體以及玻璃纖維紗束拉力實驗共15組試體。以上將藉由實驗結果與探討，將GFRP構件設計施作成「GFRP植生窗框」，供藤蔓植物進行攀爬。最後除了計算「GFRP植生窗框」碳足跡外，並以不鏽鋼材(SUS304)與鋁合金(6063-T5)材料模擬針對「GFRP植生窗框」之整體碳足跡減量效益進行探討。本研究乃運用FRP材料優於金屬材料之特性，應用於「植生壁面綠化系統」，以克服現有立面綠化之金屬結構的缺點，期許對於臺灣都市環境中之建築物發展植生壁面綠化技術能有所助益。

In this thesis, the application of light weight, high strength, anti-corrosion, weather resistant and heat insulation Glass Fiber Reinforced Plastic (GFRP) composite members to “Green Vegetation Units” to replace similar green facades made of metal materials is presented.
Experiment was conducted on the bio-compatibility and mechanical behavior of the FRP components. In the bio-compatibility experiments, 2 species of vines - Pyrostegia venusta and Ficus pumila – were supported by 2 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). For each of the 2 species of vines, 3 plant pots were allocated making it a total of 36 specimens in the experiment. The mechanical testing of the GFRP components include the three-point bending experiment; 3 specimens in the chemical bonding experiment and 3 specimens in the physical bonding experiment respectively; and the tensile strength experiment of 15 Glass fiber bundle specimens. From the results of the experiments discussed above, an “GFRP vegetation window frame” for vines to climb on was designed using the GFRP components. Finally, in order to investigate the carbon footprint and carbon reduction benefits of the “GFRP vegetation window frame”, carbon footprint comparison was made with that of a similar stainless steel (SUS304) frame and aluminum (6063-T5) before discussing the overall carbon footprint reduction benefits of the “GFRP vegetation window frame”.
This study focuses on the superiority of GFRP materials over metal materials in making “Green Vegetation Units” in order to overcome the disadvantages of similar existing Green facades expected to be useful on urban buildings in Taiwan.
