| 摘要: | 本研究以聚苯并噁唑纖維及克維拉纖維為芯材，搭配不同之外層包覆材，經由反覆拉伸測試下，分析其應用於飛行傘飛行時之飛行傘傘繩延伸率及其強力下降率。由實驗得知聚苯并噁唑編織繩具有細丹尼、高強力及低延伸率外，經由反覆拉伸模擬飛行時其強力下降率亦為較佳者。
We use the PBO fiber and Kevlar fiber to be the main core materials with different cover wraps, which underwent recursive stretch tests, to analyze the elongation rate and lowering rate of the rope strength is in this experiment. From the end result, we realize that PBO fiber ropes with minor denier, high strength and low elongation rate are the better choices while undergoing the recursive simulated flight tests. |
