FIELD: textile, paper.

SUBSTANCE: bullet-proof fiber composite comprises a variety of adjacent layers on the basis of fibers, where each layer on the basis of fibers comprises synthetic fibers with a high tensile modulus, characterized by the surfaces which are at least partially covered with a polymeric material, where the said fibers do not basically comprise any fibers protective cover so that the said polymeric material is mainly in direct interaction with the surfaces of the fibers. The said fiber composite is characterized by the value of dynamic tensile modulus which exceeds the value of the dynamic tensile modulus of the comparable fiber composite, characterized by the fiber surfaces, which are mainly covered with a fiber protective cover. The said fiber protective cover is disposed between the fiber surfaces and the polymeric material. Methods for manufacturing of bullet-proof composite are also described.

EFFECT: invention provides a composite with improved resistance properties against bullets and shrapnel, in particular improved values of dynamic tensile modulus that correlates with the composite low depth of cup.
