The collaborative project of Saint Jean Industries and Hexcel in the final of the JEC Innovation Award 2019

Every year, JEC rewards the best cutting-edge and ingenious projects using composites to their full potential. Created in 1998, the goals of this top-level innovation program are to:

  • Identify, promote, and reward the most innovative composite solutions worldwide
  • Encourage companies that are involved in composite innovation along with their partners
  • And also enhance their public exposure; and contribute to the advancement of the composite industry

This year, more than 100 projects were proposed, and after a review of the applications by an international jury of experts, 30 finalists are still in the race in the various innovation categories. Our collaborative project on the lightening of aluminium cradles has been selected in the “automotive application” category.

For cars, the trend towards lighter weight is still strong today, as it allows combustion vehicles to reduce their fuel consumption and emissions, and electric vehicles to improve their autonomy. But at the same time, we can see that weight reduction must be controlled, because it leads to a deterioration in the vibro-acoustic behaviour of vehicles. This was especially true for vehicles with electric motors, as the frequency zones are very different. This sometimes leads to the addition of dead masses simply to avoid this degradation….

This is why our innovation aims to push the limits of weight reduction, by improving the acoustic and vibration performance (NVH) of an aluminum cradle using composite patches. Hexcel’s expertise in the field of composites and their application, combined with Saint Jean Industries’ experience in chassis and structural parts engineering, have made it possible to find a lightweight and economically viable solution. In addition, this solution offers great flexibility in its application. It can be part of a classical design approach at a very early stage, or it can take part at the end of the chain when unusual vibro-acoustic behaviour is observed.

Finalists are selected according to several criteria such as the involvement of partners in the value chain, technicality or commercial applications of innovations. See you on Wednesday afternoon, March 13 at the JEC World show in Paris to discover the winners of the competition.
