Extracting process of stratospheric airship envelop fabric fiber

  • 摘要: 平流层飞艇高度以及昼夜温差改变,都将引起飞艇内外压差有很大的变化.飞艇蒙皮承力层纱线拔出是其撕裂现象的细观过程,对飞艇耐压能力有着重要的影响.对某平流层飞艇蒙皮材料织物层进行细观力学建模,通过研究纱线拔出过程力的变化,并与试验结果对比,指出整个拔出过程可以分为近似线性增长阶段和振荡阶段,两阶段过渡点纱线拔出力的大小对于蒙皮材料撕裂扩展性能有着重要意义.同时,平流层紫外和臭氧等复杂环境,通过对织物纱线表面老化,降低其表面性能,从而使得最大拔出力减小,飞艇耐压能力降低.
