    Abstract: A polymer-bonded fiber agglomerate includes short fibers selected from carbon, ceramic materials, glasses, metals and organic polymers, and a polymeric bonding resin selected from synthetic resins and thermoplastics. The fiber agglomerates have an average length, measured in the fiber direction, of from 3 mm to 50 mm and an average thickness, measured perpendicularly to the fiber direction, of from 0.1 mm to 10 mm. At least 75% of all of the contained fibers have a length which is at least 90% and not more than 110% of the fiber agglomerate average length. A fiber-reinforced composite material having the fiber agglomerate and processes for the production thereof are also provided.
