Flachmaterialstreifen und Verfahren zur Herstellung von Faserverbundwerkstücken mit derartigen Flachmaterialstreifen

摘要

The invention relates to a flat material strip used for the production of fibre composite workpieces by arranging same on shaping surfaces, comprising reinforcing fibres (40, 42) which are arranged in a defined orientation to a longitudinal direction of the flat material strip, are positioned next to each other in a strip surface and together form a mat (38). To improve said flat material strip in such a way that it can be easily draped, i.e. that it can be easily laid out on complex surfaces, for example doubly curved surfaces, the invention provides for the mat (38) to have reinforcing fibres (40, 42) which can be moved towards each other within the mat in such a way that the mat can be stretched in limited localized areas in a longitudinal direction and that the flat material strip in an area (20) extending in a longitudinal direction across part of the width of said flat material strip comprises a substantially inelastic fibre (50) extending in the longitudinal direction which aids in the placement of the mat.
