Solid rocket booster field joint
Webis made of a fluoroelastomer, which seals the joint between two solid rocket booster sections. An elastomer is a material that can be deformed dramatically and recover its shape completely. A rubber band is an example of an elastomer. In almost half of the shuttle flights there was O-ring erosion in the booster field joints. WebFeb 1, 1996 · Faulty O-rings, normally flexible and pliable, but frozen stiff by the cold weather, were identified as the reason for the Challenger explosion, which resulted in the loss of seven astronauts. The following article reports on the improvements that have been made to sealing the solid rocket motor field joints since the disaster.
