Hexel 
The carbon prepreg patch technology from composites company Hexcel Corp., Stamford, CT/USA, has been selected as a finalist for the JEC Innovation Awards 2019 in the Automotive category. The composite solution improves the performance of aluminum sub-frames by reducing noise, vibration and harshness (NVH).
HexPly patches consist of uni-directional carbon fiber and an epoxy matrix with fast curing self-adhesive properties that enable it to bond to metal in a highly efficient 1-step process. 500 g of HexPly prepreg were added to the aluminum sub-frame, and the test results demonstrated a positive effect on improving overall NVH performance. Aluminum sub-frames are significantly lighter than traditional steel versions.
Benefits of this innovation include lower production costs, energy savings, increased driver comfort, production flexibility and part count reduction. The technology is adaptable for thermal engine, electric or fuel cell vehicles.
The award winners will be announced during JEC World 2019, which takes place from March 12-14 in Paris/France, and where Hexcel will showcase its new HexPly carbon patch technology among other composite innovations for the Automotive, Marine, Wind Energy and Aerospace sectors.
