Abstract
The invention relates to a fixing threadfor sewing together reinforcing fibers, in particular to form a fiber preform, for the production of a fiber-reinforced composite component by means of impregnation with a curable polymer material. According to the invention, the fixing threadhas an interfacefor locally increasing the ductility of a matrix formed by the curable polymer material and has at least one core thread, so as in particular to reduce the tendency for microcracks to form in the matrix of the finished composite component in the regions where the fixing threadspenetrate. The interfacemay be formed, for example, by an enclosure of the core threadby a thermoplastic polymer material, for example by polyethylene, polypropylene or the like.
