Abstract

The invention relates to a vehicle component made of plastic, in particular a vehicle body shell component, with at least one supporting layer, with at least one outer skin and with at least one tear-resistant splinter protection layer. According to the invention, the splinter protection layer is formed as a splinter protection fabric and is embedded in the at least one supporting layer, in particular in the edge region thereof, or between two adjacent layers. The splinter protection fabric has the effect of avoiding sharp-edged breaks of the vehicle component in an accident.

Claims (46)

1. A vehicle component made of plastic,

in particular a vehicle body shell component, such as a vehicle roof module, vehicle door, roof post, vehicle pillar, wing, engine compartment cover, luggage compartment cover, rear-end module, roof shells of cabriolet hoods, front or rear spoilers,

with at least one supporting layer,

with at least one outer skin,

and with at least one splinter protection layer,

wherein

the splinter protection layer is formed as a splinter protection fabric and

is embedded between two adjacent layers or in one of the supporting layers, in particular in the region thereof near the edge.

2. The vehicle component as claimed in claim 1 , wherein the at least one supporting layer consists

of polyurethane (PU) or some other thermoset and/or

of a honeycomb layer or a foam layer of plastic or metal or a layer of some other core material and/or

of a glass fiber mat and/or

of a decoupling layer.

3. The vehicle component as claimed in claim 1 , wherein the at least one supporting layer or at least one of a number of supporting layers is produced

by the composite spray molding process (CSM process) and/or

by the long fiber injection process (LFI process) and/or

by the glass fiber mat polyurethane process (GM-PU process) and/or

by the resin transfer molding process (RTM process) and/or

by the sheet molding compound process (SMC process) and/or

by the reaction injection molding process (RIM process) and/or

by the reinforced reaction injection molding process (RRIM process) and/or

by the injection molding process.

4. The vehicle component as claimed in claim 1 , wherein the at least one splinter protection fabric consists

of polyethylene (PE) and/or

of polyethylene terephthalate (PET) and/or

of polyamide (PA) and/or

of polypropylene (PP) and/or

of aramid and/or

of elastic polyurethane (PU) and/or

of natural or synthetic rubber and/or

of a steel mesh.

5. The vehicle component as claimed in claim 1 , wherein the supporting layers thereof consist, from the inside outward,

of a first layer of polyurethane (PU),

of a core layer created by honeycomb technology,

of a second layer of polyurethane (PU),

of a decoupling layer and

of an outer skin,

at least one splinter protection fabric being arranged

between the first layer of polyurethane (PU) and the core layer

and/or

between the second layer of polyurethane (PU) and the core layer

and/or

between the second layer of polyurethane (PU) and the decoupling layer.

6. The vehicle component as claimed in claim 1 , wherein a glass fiber mat is embedded as reinforcement in at least one of the supporting layers of polyurethane or some other thermoset.

7. The vehicle component as claimed in claim 1 , wherein the outer skin is colored in the desired vehicle color.

8. The vehicle component as claimed in claim 1 , wherein the vehicle component has an overall thickness of 2 mm to 60 mm.
