Many inventions being in common use today would not exist without the application of technologies and materials developed specifically for aviation and space exploration. And many of these solutions have now quite terrestrial applications...
It happens that the realization of space missions is possible due to pioneering technologies formerly developed on Earth. It is generally believed that one of the fruits of the Apollo project was the invention of super plastic material - Teflon. Well, teflon was already known in the thirties, and you could buy teflon pans for ten years before landing the first man on the Moon. The truth, however, is that this material fulfilled a very important role in the project Apollo. It was used to cover, among the others, fibers building special material for the American spacesuits.
Even earlier, in the forties, teflon was used in the Manhattan Project, whose goal was to produce an atomic bomb. In 1969, which was the same year when the man first walked on the Moon, a very interesting material was invented while looking for fabrics and substances useful for the space industry - it was Goretex. In fact, Goretex consists of the same teflon that covers pans, but combined with textile fabrics to create semipermeable material!
In turn, in the 60s of the twentieth century so-called aromatic polyamide fibers known as aramids were invented. These highly strong and durable fibers were produced by DuPont under the trade name Nomex. These fibers resembled already known fibers, but were much, much stronger, up to eight times more in comparison to the popular polyesters. They began to be used in air filters, protective clothing, and even as a substitute for asbestos.
Based on previous work by Bayer, in the 60s and 70s new para-amide fibers, characterized by even greater strength and higher modulus of elasticity, were discovered by DuPont and Akzo Nobel. In 1973, DuPont introduced the first para-amide fiber called Kevlar. Related fiber called Twaron with the same chemical structure was introduced by Akzo in 1978.
Kevlar and Twaron fibers are still in use in many highly developed industries: aerospace, space and military (in bulletproof vests!). Annually people produce more than 50 thousand tons (!) of para-amides, of which a part is also for the production of sails. Another product created based on the works related to space and aerospace industry is copolyamid, best known as Technora and first created in 1976.
