Wall for a motor vehicle body
A wall suitable for a motor vehicle body, in particular a passenger vehicle, is formed by a laminate body of multiple plastic layers. To optimize visible surface area, the wall has the layer structure in which a first outer layer is formed by a resin film, a second layer is formed by a nonwoven adjacent to the first layer, and a third layer is adjacent to the second layer and has at least one unidirectional layer.
1 . Wall for a motor vehicle body passenger vehicle, comprising a laminate of plastic layers including,
a resin film first outer layer,
a nonwoven second layer adjacent to the outer layer, and
a third layer having at least one unidirectional layer adjacent to the second layer.
2 . Wall as claimed in claim 1 , further including a fourth layer of unidirectional woven fabric adjacent to the third layer.
3 . Wall as claimed in claim 2 , further including a fifth layer, with a sixth and seventh layers of woven fabric applied to the fourth layer.
4 . Wall as claimed in claim 1 , wherein the second nonwoven layer is joined to at least one of the layers adjacent thereto.
5 . Wall as claimed in claim 1 , wherein the second layer is joined mechanically to at least one adjacent layer.
6 . Wall as claimed in claim 5 , wherein the mechanical joining is a sewn joint.
7 . Wall as claimed in claim 1 , wherein the second layer is a prepreg.
8 . Wall for a vehicle body, comprising a laminate of plastic layers, including a nonwoven outer layer and another layer being adjacent to the outer layer and having one or more unidirectional layers.
9 . Method for manufacturing the wall as claimed in claim 1 , comprising introducing at least the first layer and the second layer are introduced into a manufacturing operation as prepregs.
10 . Method as claimed in claim 8 , further comprising introducing other layers into the manufacturing operation as prepregs.
11 . Method as claimed in claim 9 , wherein at least one layer is impregnated by the next adjacent layer.
12 . Method as claimed in claim 9 , wherein certain layers are prepregs, and the outer layer is jointly impregnated by the certain prepreg layers.
13 . Method as claimed in claim 9 , wherein certain layers are assembled in an unimpregnated condition and are then are impregnated with resin by an injection method.
14 . Method as claimed in claim 9 , wherein a spray film is applied to an outside surface of the outer layer.
