Beschreibung
Zusammenfassung:	A prepreg peel ply material (21) to be used for improving the surface roughness of a composite laminate (13) comprising a backing paper (23) and a base fabric (27) impregnated with a thermosetting resin, wherein the adherence between the backing paper (23) and the base fabric (27), measured by a peeling off parameter P is comprised between 2,9-3,5 min/N/cm2 and the adherence between the base fabric (27) and the composite material, measured by said parameter P is comprised between 130-160 min/N/cm2. The invention also refers to a method for determining the adaptability to an ATL machine of a prepreg peel ply material (21) including the obtention of said parameter P and to a method for manufacturing a composite component comprising an step of laying-up a peel ply base fabric (27) with an ATL machine as the last layer of said component and even as the first layer.
