The results on the brake and acceleration tests were in accordance with the requirements and the previous simulations, proving the validation of the product.
The results on the fatigue lifecycle tests did not show any structural failure and the aging also did not cause degradation in the performance of the parts, in both the static tests of braking and acceleration.

Improvements on the process:–> cycle times–> resources
Improvement in the part complexity: –> hybrid components successfully achieved–> best adhesion
The main objective on thereduction of the number ofsteps, envisioning the one-shotprocess was successfullyachieved.
