Method of producing textile preforms for fiber reinforced composite products from textile semi-finished articles
First Claim
1. A method of producing a textile preform for the subsequent manufacture of a fiber reinforced plastic composite product, comprising the steps:
- a) producing a semi-finished textile material including unfixed fibers that are not yet entirely finally fixed, by a textile production process;
b) by a reforming and/or draping process, reforming and/or draping said semi-finished textile material to re-orient said unfixed fibers into a desired fiber orientation of said preform; and
c) applying said semi-finished textile material onto a carrier having a geometry adapted to a final intended geometry of said preform, to thereby form said preform having said final intended geometry.

Abstract
A method of producing a textile preform to be used for making a fiber reinforced plastic composite product involves the following steps. A two- or three-dimensional semi-finished textile material or article is produced by essentially any textile production process, such as weaving, knitting or braiding. A binder is applied to the textile material, which is then subjected to a reforming and/or draping process by being applied onto a carrier and reforming tool having a contour or geometry adapted to that of the desired preform that is to be produced. Thereby, the previously unfixed fibers of the textile material are brought into the desired finished orientation and are then fixed, and the cross-sectional shape of the material is changed. This produces the preform having the desired contour, geometry and fiber orientation. The preform may then be subjected to further processing steps to form the finished composite product.
