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.
