| Résumé : |
One means of ensuring that bonded joints achieve their maximum strength, in addition to the use of suitable surface treatments, is to improve the joint design. In the Protron project at Trier University of Applied Sciencees, researchers investigated the design methods that would increase the strength of the bonds used to manufacture a monocoque chassis. |
