Patent number: 6048486Abstract: In a process for forming contours in aramide flat structures, in particular textile flat structures made from aramide fibers, contouring is performed by molding in a temperature range of 180-300.degree. C. and a press pressure range of 4-8 bar (400-800 kPa). The flat structures contoured by molding are suited in particular for the manufacture of antiballistic women's protective clothing as well as of antiballistic helmets. The effectiveness against penetration of bullets and splinters is not affected by the molding process.Type: GrantFiled: January 30, 1997Date of Patent: April 11, 2000Assignees: Triumph International AG, Akzo Nobel Faser AGInventors: Achim Fels, Jorg Wintersieg, Michael Mohr, Dieter Holzhauer, Franz Palzer

Patent number: 6034004Abstract: Protective clothing comprising one protective layer or a plurality of protective layers superimposed on and optionally joined to one another may contain textile flat structures made from antiballistically acting fibers, wherein the protective layers contain contoured shapes for fitting to body shapes imparted by a molding process that is conducted without the concurrent use of a resin. The protective clothing may also contain one or more cover layers. Bulges are formed in the protective layer and optionally the cover layers by the molding process in order to produce a better fit, particularly in the bust region. Protective clothing manufactured in this way offers an agreeable degree of comfort and is particularly intended for female police, military and other security personnel.Type: GrantFiled: January 30, 1997Date of Patent: March 7, 2000Assignees: Triumph International AG, Akzo Nobel Faser AGInventors: Achim Fels, Jorg Wintersieg, Michael Mohr, Dieter Holzhauer, Franz Palzer
