AROOA project aims to study and optimize a new family of prepregs designed for out-of-autoclave processing of composite materials in collaboration with Hexcel. This new technology allows savings in the manufacturing of components and structures for aircrafts. AROOA project will be carried out by the Structural Composites and Micro- and Nano- mechanics groups of IMDEA Materials Institute, integrating their know-how in advanced characterization and modelling.
