HayonsLe hayon sur une automobile, est l'ensemble constitué de la lunette arrière et de la porte de coffre, le tout s'ouvrant ensemble. Par extension on parle de voiture à hayon, en anglais carrosserie hatchback. Apparu dans les années 1950 chez Kaiser et les années 1960 sur les berlines familiales (Renault 4, Renault 16, Simca 1100…) et très populaire en France, ce type de carrosserie s'oppose aux berlines tricorps (trois volumes) à lunette arrière fixe.
Il est généralement équipé d'un essuie-glace et d'un système de dégivrage. (Wikipedia)

| Résumé : |
Until now, only metal has been used for the tailgates of VW cars. In its top of the line electric model, the ID.3, Volkswagen is now using a plastic-metal composite for the first time. One of the materials used for its production is a long glass fiber-reinforced polypropylene from Celanese. The material was required to not only satisfy the mechanical demands, but also enable an attractive appearance. |
| Note de contenu : |
- Plastic/metal hybrid instead of steel
- Extensive demands
- Bonded instead of bolted
- All additives incorporated in one step
- Uv protection and odor requirements met with adapted formulation
- Tapes could be used as substitutes for metal inserts
- Tapes and injection molding material form a solid unit
- Fig. 1 : The demands on the structural and visible part of the tailgate of the ID.3 electric runabout are numerous. They were met with various material modifications
- Fig. 2 : One part of the tailgate is a visible interior part. The FRP used have a very good surface quality and therefore do not have to be additionally painted. They are supplied as pre-pigmented pellets in the desired vehicle interior color
- Fig. 3 : Production of Celstran LFT : the pultrusion technology allows the fibers to be completely impregnated
- Fig. 4 : Since the demands on the tailgate and rear spoiler support differ, they were produced using different materials
- Fig. 5 : The strands produced by pultrusion can be rolled out into 300 mm wide tapes
- Fig. 6 : Schematic illustration of the development of fully impregnated continuous fiber-reinforced tapes: the tapes can be wound onto spools and then processed by injection molding |
