The new generation of complex composites structures that will be developed by Hutchinson and its partners will integrate several functions, as esthetic interior panel, acoustic, thermal and vibration isolation, in addition to mechanical and robustness contribution brought by the integrated structure. These new technologies will allow to reduce the amount of parts, and also to reduce the amount of operations required to build an assembly, generating an energy saving in the global process. The self-stiffened part that will be developed will also permit to replace traditional metal components in the structure by composite materials. Combined with the optimization of the design, a weight reduction will be achieved, generating a reduction of fuel consumption.
