Résumé : |
Weight reduction is one of the major requirements of automotive components. Regardless of the vehicles in which they are used. One of the lightest materials that can be considered is polypropylene (PP). With the right reinforcements, it is also suitable for demanding vehicle components. This is demonstrated by its use in ‧vehicles such as the NIO ES8. |
Note de contenu : |
- Need for weight reduction drives innovation in automotive exteriors and structural parts
- Carbon fiber-reinforced PP : when stiffness matters most
- PP foams : keeping cool without draining the battery
- Sustainability : higher on the agenda than ever before
- Figure : The chines manufacturer NIO uses carbon fiber-reinforced PP compounds for the center console support of the ES8 electric SUV
- Fig. 1 : PP compound Daplen EE001 Al has good scrtch resistance and surface quality despite its low material density of 0.95 g/cm3. Skoda therefore relies on this material for the door trim of its Scaa
- Fig. 2 : Glass-fiber-reinforced PP is suitable as a PA replacement. For example, the front end module of Borealis is made of the material
- Fig. 3 : Comparison of the bending stiffnes (E 1/3/p) of different lightweight materials (number in the bars indicates the density in g/cm3) : the filler content of all plastics is 40%
- Fig. 5 : In order to be able to simulte components in a meaninful way, comprehensive material characterization by the manufacturer is necessary. This requires material tests such as tensile tests
- Fig. 6 : Foamed components reduce the weight and thus also the energy consumption of the vehicles. Foaming is therefore an interesting option, especially for electric vehicles |
