Abstract
The invention relates to a preformed sheet comprising at least two mono-layers, each mono-layer containing a fibrous network with fibers having a tensile strength of at least about 1.2 GPa and a tensile modulus of at least 40 GPa and a binder, and a separating film on at least one of its outer surfaces, characterized in that the separating film has an areal density of between 1 and 5 g/m. With this preformed sheet assemblies and articles offering a substantially higher ballistic protection level at a certain weight can be obtained. The invention further relates to an assembly of at least two such sheets and to a flexible ballistic-resistant article comprising said assembly.
