中文摘要 | 本研究利用粒片狀、細碎片狀及長薄片狀共3種不同原料型態製備鋁箔包複合材(Beverage carton composites,BCC),並以萬能強度試驗機、X-ray密度分析儀(X-ray density profiler)、動態機械分析儀(Dynamic mechanicalanalysis,DMA)及掃描式電子顯微鏡(Scanning electron microscopy,SEM)等評估複合材之物理機械性質、密度剖面、動態機械性能及顯微結構,以探討原料型態對複合材性質之影響。試驗結果顯示,3種BCC中以粒片狀原料製備者具有較佳之尺寸安定性及內聚強度。相對的,以長薄片狀製備者具有較佳之抗彎強度、抗彎彈性模數及儲存模數。至於厚度方向之密度剖面,3種BCC間則無明顯差異,皆呈現均勻分布。而由SEM影像中發現,原料型態會影響BCC之顯微結構,以粒片狀及細碎片狀製備之BCC中含有較多之空腔,而以長薄片狀製備者則具有連續的裂縫。綜合上述結果顯示,原料型態會顯著影響鋁箔包複合材之性能表現。 |
英文摘要 | In this study, beverage carton composites (BCC) were made from various furnish shapes, including particle-, confetti-, and flake-types of recycled beverage cartons. Effects of furnish shape on the physicomechanical property, vertical density profile, dynamic property, and microstructure of BCC were evaluated by a universal testing machine, X-ray density profiler, dynamic mechanical analyzer (DMA), and scanning electron microscopy (SEM), etc. The experimental results showed that the particle-based BCC exhibited superior dimensional stability and internal bond. On the contrary, the flake-based BCC showed higher bending strength, bending modulus, and storage modulus. In addition, similar and uniform density profiles were observed for all types of BCC. SEM micrographs revealed that the furnish shape significantly affected the microstructure, in which more voids were observed in particle- and confetti-based BCC, while continuous gap distribution was observed in flake-based BCC. Accordingly, these results indicated that the furnish shape significantly influences the performance of BCC. |
