Vectran is a manufactured fiber, spun from a liquid-crystal polymer (LCP) created by Celanese Corporation and now manufactured by Kuraray. Chemically it is an aromatic polyester produced by the polycondensation of 4-hydroxybenzoic acid and 6-hydroxynaphthalene-2-carboxylic acid. Vectran fibers are used as reinforcing (matrix) fibers for ropes, electrical cables, sailcloth, and advanced composite materials, professional bike tires, and in electronics applications. It is used as one of the layers in the softgoods structure of NASA's Extravehicular Mobility Unit (spacesuit) designed and manufactured by ILC Dover and was the fabric used for all of the airbag landings on Mars: Mars Pathfinder in 1997 and on the twin Mars Exploration Rovers Spirit and Opportunity missions in 2004, also designed and manufactured by ILC Dover . The material was used again on NASA's 2011 Mars Science Laboratory in the bridle cables. More information...
