ABSTRACT:
A preformed sheet is provided with at least two mono-layers, each mono-layer containing unidirectionally oriented fibers having a tensile strength of at least about 1.2 GPa and a tensile modulus of at least 40 GPa, and a binder, with a fiber direction in each mono-layer being rotated with respect to the fiber direction in an adjacent mono-layer. A separating film is provided on both outer surfaces, the separating film having a porosity of between 40 and 90%. Assemblies and articles with such preformed sheet offer a substantially higher ballistic protection level at a certain weight. An assembly of at least two such sheets and a flexible ballistic-resistant article which includes such an assembly are also provided.
