In the building Membrane material It is mainly developed with the progress of modern fine chemical technology. In the early days, PVC was used as the surface coating and polyester fiber as the base material. Now it is called Grade C membrane (PVC/PES) structure. The mechanical properties of buildings (structures) are not ideal. At the same time, the application of neoprene coating and glass fiber based cotton natural fiber coating is less.

  In the 1960s, the technology of glass fiber fabric film was widely developed and applied, but the surface coating material was still polyethylene (now called Class B film). The membrane material has the characteristics of high strength, high modulus and low creep, but its self-cleaning and durability are not ideal. At the same time, the manufacturing process of Class C membrane materials has also been improved, and the membrane structure and architectural characteristics have gradually improved.

In the early 1970s, NASA developed a surface coating material of polytetrafluoroethylene (chemical name Fife, trade name Teflon, 1938) with excellent architectural performance. At the same time, the glass fiber fabric membrane technology of B yarn and de yarn is also becoming more and more mature, which makes the modern fabric membrane material based on polytetrafluoroethylene come out, now known as class a membrane, and starts engineering application [Z]. With the development of new polyester fibers (Kevla, etc.), fluoride coatings are gradually applied to C-type films.

In the 1980s, due to the development and demand of aerospace science and technology, fine chemical technology, fluorine fiber (polytetrafluoroethylene, fluorinated ethylene propylene, polyfluoroethylene, etc.), carbon fiber (CF), polyester fiber (PbO, pet, etc.) and other fabric films were developed one after another. These films are characterized by high strength, high specific strength, high modulus, radiation resistance, atomic oxidation resistance, and stable performance. But at present, they are mainly in the field of construction.
