峰巢結構目前在各領域都有很多的應用,更因為了蜂巢結構所提供的強度以及低成本,所以在包裝產業中有良好的運用。在本研究中以TPU的彈性回復能力,結合蜂巢結構,以取代一般使用鋁片製成的蜂巢式緩衝材料,藉以獲得更良好的緩衝性能。TPU的高彈性回復亦可以提高可重覆使用的可能性,降低包裝材的耗損與浪費。在本研究中,以落重式衝擊測試來評估不同厚度之TPU蜂巢式氣墊的緩衝性能,藉由疊層方式的變化,改變其衝擊吸收之特性,以提高其緩衝性能。研究中發現,TPU蜂巢式氣墊的緩衝能力會隨厚度增加而提高,但是以8 mm為最佳,10 mm反而衝擊性能會略微下降,而使用較薄的TPU峰巢式氣墊置於衝擊接觸面,能提高整體之緩衝性能,以2 mm/8 mm 疊層的TPU蜂巢式氣墊可提供最佳的緩衝性能。
Honeycomb structures have widely used in various fields, it has high strength and low cost. Ii this study, Thermoplastic Polyurethane Honeycomb air cushion (TPU-HAC) was used to replace cellular aluminum; owing to TPU-HAC has excellent elasticity and good impact resistance. For this reason, we used following weight impact testing to evaluate impact resistance of various thicknesses TPU-HAC (2, 4, 6, 8 and 10 mm). The result indicated the impact resistance of TPU-HAC was increased with thickness increasing. The impact resistance was optimum when the thickness of TPU-HAC was 8 mm.
