Abstract:
1. A process for the manufacture of an anti-ballistic article comprising the steps of: (a) forming a stack of sheets by stacking 2 or more sheets, each sheet comprising one or more mono-layers of anti-ballistic fibers, followed by (b) subjecting the stack of sheets to a reduced atmospheric pressure environment having an absolute gaseous pressure of no more than 0.1 MPa; and (c) while maintaining the reduced atmospheric pressure environment, consolidating said stack of sheets to a pressure of at least 10 MPa at an elevated temperature of at least 10° C. below either a melting temperature of the anti-ballistic fibers or a temperature at which the anti-ballistic fibers lose mechanical properties.
