Abstract
The invention relates to a method for the preparation of a transparent antiballistic article. The method comprises providing a plurality of anisotropic polymeric film layers, stacking the film layers to form an assembly and compressing the thus formed assembly at a temperature and pressure sufficient to consolidate the film layers, whereby the temperature is not more than 50° C. below the melting temperature of the polymer, the pressure is at least 80 MPa and sufficiently high to obtain an optical transparency according of at least 50% transmission. The invention also relates to a ballistic resistant article having an energy absorption for 17 grain FSP according to the STANAG 2920 standard of at least 10 J/(kg/m) and an optical transparency according of at least 50% transmission.
