Tempe, May 30th 2017 - Solvay congratulates United Aircraft Corporation and AeroComposit on the first flight of the MC-21 aircraft. The MC-21 is the only single-aisle passenger plane with composite wing structures manufactured by AeroComposit with out-of-autoclave resin infusion technology.


Solvay’s resin infusion material technology was selected to manufacture the wing structures which included dry carbon fiber slit tape PRISM® TX 1100 and PRISM® EP 2400 toughened resin.
