The invention relates to a preformed sheet comprising mono-layers from a fibrous network with fibers having a tensile strength of at least about 1.2 GPa and preferably a binder, and a separating film on at least one of its outer surfaces, the separating film having an areal density of between 1 and 10 g/m2 and a surface tension of less than 35 mN/m at the surface faced to the fibrous network and the separating film has a crystallinity of between 50 and 90 %. |
