Method and device for the production of tubular structural components

摘要

A method for producing a tubular structural component and device for production thereof are disclosed. A tubular molding tool has an inner mold surface shaped corresponding to an outer surface of the structural component. A support surface of an expandable support, formed corresponding to the molding tool shape such that in an unexpanded state the support fills the molding tool while the support surface and the mold surface run parallel leaving an expansion spacing of the support surface to the mold surface, is covered with a tubular non-crimp fiber fabric, such that fibers of a fiber layer of the non-crimp fiber fabric run diagonally around the support. After the support has been arranged in the molding tool, the non-crimp fiber fabric is pressed against the mold surface by expanding the support with radial expansion of the non-crimp fiber fabric. The non-crimp fiber fabric is infiltrated by a curable matrix.

1. A method for producing a tubular structural component, comprising the steps of:
providing a tubular moulding tool which has an inner mould surface shaped corresponding to an outer surface of the structural component; covering a support surface of an expandable support, which is formed corresponding to the shape of the moulding tool such that in an unexpanded state the support fills the moulding tool while the support surface and the mould surface run parallel to one another leaving an expansion spacing of the support surface to the mould surface, with a tubular non-crimp fibre fabric, such that fibres of a fibre layer of the non-crimp fibre fabric run diagonally around the support; arranging the support in the moulding tool; pressing the non-crimp fibre fabric against the mould surface by expanding the support with radial expansion of the non-crimp fibre fabric; and infiltrating the non-crimp fibre fabric with a curable matrix.
