飞艇囊体材料的发展

The Development of Airship Envelope Materials

飞艇的先进性无不和它所用囊体材料的性能息息相关。囊体材料的性能主要包括力学性能、气密性、耐运用性、易成型性、耐候性和低重性。现代工业的发展使飞艇囊体材料在提高其性能方面有了长足进步,相应材料结构形式从不同发展阶段的胶布材料发展到新近的薄膜/织物层压复合材料。评定囊体材料性能的有效试验方法日趋成熟。但现今囊体材料还存在一些不足。本文对上述内容进行了评述。

The advanced availability of an airship is strongly related with the performances of the envelope mare-rials (EM) used.The performances of the EM mainly include mechanical properties,permeability, handingstrength, efficiency of seams,environment resistance and light-weight,etc.The modern industry devel-opment be made a long-step advancement for improving the performances of airship EM.And the corre-sponding materials structure forms have a developing history from various kinds of rubber-coating cloth tothe latest film-weave laminate composite materials.The efficient test methods for evaluating EM ate gradu-ally matured.But there are still some defects in the present EM. All above mentioned contents are reviewedor discussed in the paper.
