Title:
METHOD FOR THE PRODUCTION OF A FIBRE COMPOSITE MATERIAL COMPONENT AND INTERMEDIATE PRODUCT FOR SUCH A METHOD
Document Type and Number:
WIPO Patent Application WO2004103665
Kind Code:
A3
Abstract:
The invention relates to a method for the production of a fibre composite material component, whereby several reinforcement fibre layers (4) are stitched and coupled to each other by means of a thread (6), to give reinforcing fibre blanks (2), the seam (6) being under a given thread tension and the reinforcement fibre blanks (2) are compacted during the stitching. The reinforcement fibre blanks (2) are laid in an injection mould, the injection mould closed, a resin injected into the injection mould and the resin hardened. The method is characterised in that the reinforcing fibre blanks (2), on stitching the reinforcing fibre layers (4), are firstly pre-compacted to a degree of pre-compacting, the reinforcing fibre blank (4) is then finally compressed (F) by the closing of the injection mould to give a final degree of compacting (D2). The seam (6), under a given thread tension, is loosened by means of said final compacting.
