| Résumé : |
The demand for electric drive systems will grow substantially over the next few years. A high degree of automation and streamlining of the manufacturing process should make it possible to produce higher volumes and more powerful batteries at lower prices. The production of a vehicle battery is tailor-made for bonding using polyurea. |

- Fig. 1 : Shear stress-shear displacement diagram of polyurea and polyurethane on CDC coated aluminum with 3 mm joint
- Fig. 2 : Shear stress-shear displacement diagram of polyurea before and after climate change test (VW, PV 1200)
- Fig. 3 : Dependence of stiffness on strain rate. The steeper the regression line, the more the material stiffens during an impact load
- Fig. 4 : DMTA curve of the flexible polyurea. The maximum peak value of tan(5) is at - 47 °C, outside the application temperature
- Fig. 5 : Development of tensile shear strength as a function of curing time (CDC coated aluminum 3 mm joint)
- Fig. 6 : Thanks to the casting of fast-curing polyurea (fluorescent blue) directly into the joint gap, a quick handling strength is achieved
- Fig. 7 : Use of polyurea (yellow) potting compounds in the vehicle battery |
