  • Patent number: 8685297
    Abstract: With a method for the manufacture of fiber-composite components, more particularly of fan blades for aircraft engines, dry fiber mats are superimposed in a lay-up mold, correctly positioned and fixed with locating pins and subsequently sewn in the mold. Metallic indicators are provided on at least one mat. The preformed entity of fiber mats is whipped at its edges with thermoplastic material and subsequently smoothed by application of heat. Remaining fiber residues are cut off. The blank thus available is infiltrated with synthetic resin in an infiltration mold or a sheathing remaining on the component. The fiber mats are checked for correct positioning by non-destructive inspection procedures. The fiber-composite component thus formed conforms to high quality requirements.
