Graphene in the Sky and Beyond

Siochi, Emilie J.

With the premium placed on strong, lightweight structures, carbon materials have a long history of use in aerospace applications. Graphitized carbon and carbon/carbon composites are used in thermal protection systems and heat shields, carbon fiber composites in aircraft, and more recently, carbon nanotubes have been used on spacecraft. As the newest member of this family of materials, graphene also has a number of interesting properties that intersect with unique aerospace requirements. Despite its many attractive properties, graphene-based structures and systems, like any other material used in aerospace, must clear a number of hurdles before it will be accepted for use in flight structures. Carbon fiber, for example, underwent a development period of several decades between initial discovery and large-scale application in commercial aircraft.
