Antiballistic panel

Abstract

The invention pertains to an antiballistic panel comprising at least a first stack and a second stack, wherein the first stack has a plurality of first laminates made of a first kind of yarn and the second stack has a plurality of second laminates made of a second kind of yarn, wherein the first kind of yarn has linear density of at least 1001 dtex measured by ASTM D1907 and a filament linear density of at most 1.2 dtex measured by ASTM D1577-07, option C-2 and the second kind of yarn has a linear density of at most 1000 dtex measured by ASTM D1907 and a filament linear density of at least 1.3 dtex measured by ASTM D1577-07 option C-2.

1 . Antiballistic panel ( 3 ) comprising at least a first stack ( 1 ) and a second stack ( 2 ), wherein the first stack ( 1 ) has a plurality of first laminates made of a first kind of yarn and the second stack ( 2 ) has a plurality of second laminates made of a second kind of yarn, wherein the first kind of yarn has a linear density of at least 1001 dtex measured by ASTM D1907 and a filament linear density of at most 1.2 dtex measured by ASTM D1577-07, option C-2 and the second kind of yarn has a linear density of at most 1000 dtex measured by ASTM D1907 and a filament linear density of at least 1.3 dtex measured by ASTM D1577-07 option C-2. 
     
     
         2 . Antiballistic panel ( 3 ) according to  claim 1 , wherein each laminate of the first stack ( 1 ) and/or the second stack ( 2 ) comprises at least one unidirectional fiber layer ( 5 ,  6 ). 
     
     
         3 . Antiballistic panel ( 3 ) according to  claim 2 , wherein the fibers of at least two unidirectional fiber layers ( 5 ,  6 ) of the laminate are arranged under an angle of 90° in respect to each other. 
     
     
         4 . Antiballistic panel ( 3 ) according to  claim 1 , wherein each laminate of the first stack ( 1 ) and/or the second stack ( 2 ) comprises at least one woven fiber layer. 
     
     
         5 . Antiballistic panel ( 3 ) according to any of the foregoing claims, wherein the panel ( 3 ) has a body face and a strike face and wherein the first stack ( 1 ) is arranged to the strike face and the second stack ( 2 ) is arranged to the body side of the panel ( 3 ). 
     
     
         6 . Antiballistic panel ( 3 ) according to any of the  claims 1 - 4 , wherein the panel ( 3 ) has a body face and a strike face and wherein the second stack ( 1 ) is arranged to the strike face and the first stack ( 2 ) is arranged to the body side of the panel ( 3 ). 
     
     
         7 . Antiballistic panel ( 3 ) according to any of the foregoing claims, wherein at least one laminate of the first and/or second stack ( 1 ,  2 ) has at least one film ( 4 ,  7 ) on its outer surface. 
     
     
         8 . Antiballistic panel ( 3 ) according to any of the foregoing claims, wherein the first yarn has a breaking tenacity higher than 2250 mN/tex measured according to D7269 and the second yarn has a breaking tenacity lower than 2249 mN/tex measured according to D7269. 
     
     
         9 . Antiballistic panel ( 3 ) according to any of the  claims 1  to  7 , wherein the second yarn has a breaking tenacity higher than 2250 mN/tex measured according to D7269 and the first yarn has a breaking tenacity lower than 2249 mN/tex measured according to D7269.
