    摘要： The disclosure relates to an apparatus for impregnating fibers (1) with a matrix material, including a unit for soaking the fibers with the matrix material. A unit for setting the fiber content by volume (100) includes at least one opening (107) through which the soaked fibers (1) are guided. Each opening (107) includes a minimum opening cross section (111) dimensioned such that matrix material is removed such that the desired fiber content by volume is achieved. The disclosure furthermore relates to a method for impregnating fibers in the apparatus.
