Patent ID: 8840988

Claim:
A fiber preform for producing fiber composite structures, the fiber preform comprising: a wall made from reinforcing fibers, wherein: the wall has a first surface, a second surface lying opposite the first surface and a thickness extending between the surfaces, and is limited by edges, the wall comprises at least one first zone made from reinforcing fiber bundles having a first resin composition and at least one second zone made from at least one fiber tape comprising at least one unidirectionally directed reinforcing yarn strand having a second resin composition, the reinforcing fiber bundles in the at least one first zone are oriented in differing spatial directions from each other when viewed in a direction parallel to the thickness extension, each reinforcing fiber bundle comprises reinforcing fiber filaments directed parallel to each other, has a length in a range from 3 to 50 mm, and contains the first resin composition in a concentration in a range from 1 to 10 wt. % relative to a fiber weight, the wall of the fiber preform has a proportion of reinforcing fibers of greater than 35 vol. %, and the at least one second zone forms a discrete region when viewed in a direction perpendicular to the thickness extension of the wall and at least one fiber tape ends with at least one end thereof inside of the wall.
