Abstract: This invention relates to a process for the preparation of an antiballistic article, the method comprising: a) Providing a transparent uniaxially stretched polymeric film with at least one layer I comprising a semi-crystalline thermoplastic polymer A and at least one layer II comprising an amorphous or semi-crystalline thermoplastic polymer B, of which polymer B has a glass transition temperature less than the melting temperature of polymer A if polymer B is amorphous or of which polymer B has a melting temperature less than the melting temperature of polymer A if polymer B is semi-crystalline; b) Stacking at least two of the uniaxially stretched polymeric films of a) at an angle a of between 45° and 135°, such that the films are in contact with each subsequent film through at least one layer II, to form an assembly; c) Compressing the thus formed assembly at a temperature above the glass transition temperature of polymer B if polymer B is amorphous, or above the melting temperature of polymer B if polymer B is semi-crystalline, and below the melting temperature of polymer A, to obtain an haze of at most 50% and having an energy absorption for 17 grain FSP according to the STANAG 2920 standard of at least 12 J/(kg/m2). The invention also relates to antiballistic articles.

Abstract: The invention relates to ballistic resistant article having a multilayered material sheet which includes a consolidated stack of unidirectional monolayers of drawn polymer, whereby the draw direction of two subsequent monolayers in the stack differs. At least one monolayer comprises a plurality of unidirectional tapes of the drawn polymer, aligned in the same direction, whereby adjacent tapes do not overlap. The invention also relates to a process for the preparation of the multilayered material sheet, and to a ballistic resistant article comprising the multilayered material sheet.
