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 molding elements, molded around at least one mold core, whereupon the matrix material is cured. After the removal of the at least one mold 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) providing a sheet-like textile support element (12) made of reinforcement fibers, which is impregnated with a curable matrix material,
- b) positioning reinforcing and molding elements (36, 38, 40, 42, 44, 46, 48) made of a fibrous material of reinforcement fibers, which is impregnated with a curable matrix material, on the support element (12),
- c1) shaping the support element (12) around at least one mold core corresponding to the contour of the cellular bodyshell structure,
- c2) joining all mutually adjoining elements by adhesive force to form a single-piece structure,
- d) curing of the matrix material,
- e) removing the at least one mold core.
A cellular bodyshell structure (52) for a motor vehicle, wherein the bodyshell structure is a single-piece component represented by a composite of a sheet-like support element (12) and a plurality of reinforcing and molding elements (36, 38, 40, 42, 44, 46, 48) made of a fibrous composite material and joined by adhesive force.
A motor vehicle having a bodyshell structure wherein the bodyshell structure is a single-piece component represented by a composite of a sheet-like support element (12) and a plurality of reinforcing and molding elements (36, 38, 40, 42, 44, 46, 48) made of a fibrous composite material and joined by adhesive force.
