  • Process for manufacturing an anti-ballistic article
    Patent number: 8535467
    Abstract: The invention relates to a process for the manufacture of an antiballistic article comprising the steps of forming a stack of sheets by stacking 2 or more sheets, each sheet comprising one or more mono-layers of anti-ballistic fibers and optionally a thermoplastic binder, followed by subjecting the stack of sheets to a reduced atmospheric pressure environment; and while maintaining the reduced atmospheric pressure environment, consolidating said stack of sheets to a pressure of at least 10 MPa at an elevated temperature. The invention also relates to an anti-ballistic article.
