PolyamidesUn polyamide est un polymère contenant des fonctions amides -C(=O)-NH- résultant d'une réaction de polycondensation entre les fonctions acide carboxylique et amine.
Selon la composition de leur chaîne squelettique, les polyamides sont classés en aliphatiques, semi-aromatiques et aromatiques. Selon le type d'unités répétitives, les polyamides peuvent être des homopolymères ou des copolymères.

| Résumé : |
Most of the energy in a crash is absorbed by metal parts. A new additional polyamide (PA) crash absorber has for the first time been integrated into the front end of the Mercedes-Benz S-Class. The advantage is that an additional loadpath could be added without significantly increasing the mass of the car. Close cooperation between the project partners and the use of suitable simulation tools were key to successful realization of this project. |
| Note de contenu : |
- Crash absorber made from fiber-reinforced polyamide
- Use of plastics previously excluded
- Motivation and challenge
- Crash absorber already in service
- Fig. 1 : Example illustrating the relevant load zone: for optimum protection of the other vehicle involved in the accident, the largest possible area should be available for energy absorption
- Fig. 2 : The crash absorber (component with triangular structures in the center of the picture) is produced from glass fiber-reinforced PA. Besides the integration of several surrounding parts, the component assists in fulfilling safety aspects
- Fig. 3 : Comparison between the simulation calculations and the drop tower tests shows the good predictability of the simulation
- Fig. 4 : For successful cooperation between the development partners, simultaneous use of the simulation software is vital |
