US 9,409,321 B2 · Moulded body for producing a fibre composite component

Abstract

A shaped body and a method for producing fiber composite components, wherein the shaped body is formed using a paper and/or cardboard material, at least in part. This makes possible cost-effective manufacture of hollow profiles of any desired length from fiber composite materials, in particular from prepreg materials and/or reinforcing fiber arrangements which are subsequently impregnated with a curable plastics material. The paper and/or cardboard material can be provided with further properties, such as gas-tightness and non-stick properties, by applying suitable functional layers. Moreover, the material makes it possible to produce highly dimensionally stable shaped bodies or support cores, in such a way that fiber composite components having highly reproducible spatial dimensions can be produced. In addition, after curing, the shaped bodies can be collapsed in a simple manner by applying a vacuum and thus removed from the fiber composite component without residues.

Dependent claims

A method for producing a fibre composite component by using a thermosetting plastics material, comprising:

forming at least one support core using at least one of cardboard and a paper, defining a geometry of the fibre composite component by the at least one support core, at least in regions,
wherein the support core, at least in regions of said support core, comprises a functional layer integrated in said support core, wherein said functional layer is a non-stick layer and a gastight sealing layer,
providing the at least one support core with a curable fibre composite material,
curing the curable fibre composite material to form a finished fibre composite component, wherein due to a gastight sealing of the support core in conjunction with a sealing surrounding the fibre composite component to be cured provides a gastight enclosure of the fibre composite component, and applying a pressure differential between the curable fibre composite component and the surrounding atmosphere during the cure process, and
collapsing and removing the at least one support core from the finished fibre composite component.
