A filler preform in a wedge form includes reinforcing fiber bundles consisting of reinforcing fiber filaments, wherein the filaments are directed parallel to each other within the fiber bundle, wherein the fiber bundle contains a first resin composition in a concentration in the range from 1 to 10 wt. % relative to the fiber weight, wherein the fiber bundles have a length in the range from 2 to 20 mm and at least 60% of the fiber bundles are reversibly fixed in a curved form within the wedge filler preform whereby flanks of the curved fiber bundles create an opening angle of less than 120° and the opening angle of the curved fiber bundles relates with an opening angle of the wedge form of the wedge filler preform. A method for producing the wedge filler preform and a method for producing a reinforcing fiber composite include a filler perform.
