Canvas, Silk and Nylon. The canopy of the parachute was initially made of canvas, which was eventually replaced by silk, which was thinner, lighter, stronger, fire resistant and easy-to-fold. In late 1930s and early 1940s, the World War affected silk import in the United States.
It works on the basic principle of 'air resistance' and 'gravity', and is used in rescue work, recreational activities and extreme sports. The fabric canopy, suspension lines and support tapes are the main components of a parachute; and all of these are made from specialized material. When the parachute is deployed, air gets trapped inside the canopy, thus making the parachute fabric stretch outwards and resist the fall.
