Abstract
The invention relates to a method for the production of a bodyshell structure for a motor vehicle, wherein a sheet-like textile support element impregnated with a curable matrix material is provided and, following the positioning of suitable reinforcing and moulding elements, moulded around at least one mould core, whereupon the matrix material is cured. After the removal of the at least one mould core, a single-piece bodyshell structure joined by adhesive force remains. The invention further relates to a bodyshell structure produced by means of this method.
Claims27
A method for the production of a cellular bodyshell structure (52) for a motor vehicle, comprising the following steps:
- a) the provision of a sheet-like textile support element (12) made of reinforcement fibres, which is impregnated with a curable matrix material,
- b) the positioning of reinforcing and moulding elements (36, 38, 40, 42, 44, 46, 48) made of a fibrous material of reinforcement fibres, which is impregnated with a curable matrix material, on the support element (12),
- c1) the shaping, in particular folding, of the support element (12) around at least one mould core corresponding to the contour of the cellular bodyshell structure,
- c2) the joining of all mutually adjoining elements by adhesive force to form a single-piece structure,
- d) the curing of the matrix material,
- e) the removal of the at least one mould core.
A cellular bodyshell structure (52) for a motor vehicle, wherein it is a single-piece component represented by a composite of a sheet-like support element (12) and a plurality of reinforcing and moulding elements (36, 38, 40, 42, 44, 46, 48) made of a fibrous composite material and joined by adhesive force.
