Reinforcing tape comprising a ply of longitudinal high-tenacity yarns

Abstract

Reinforcing tape ( 1 ) that includes a ply ( 2 ) of longitudinal, aramid-, glass- or carbon-based high-tenacity yarns ( 3 ) bound together by weft yarns ( 4 ), which tape includes two thermoplastic films ( 5, 6 ), each placed on one side of the ply ( 2 ) of high-tenacity yarns ( 3 ).

1 . A reinforcing tape ( 1 ) that includes a ply ( 2 ) of longitudinal, aramid-, glass- or carbon-based high-tenacity yarns ( 3 ) bound together by weft yarns ( 4 ), which tape includes two thermoplastic films ( 5 ,  6 ), each placed on one side of the ply ( 2 ) of high-tenacity yarns ( 3 ).  
     
     
         2 . The reinforcing tape ( 1 ) as claimed in  claim 1 , wherein each thermoplastic film ( 15 ,  16 ) adheres to one side of the ply ( 2 ).  
     
     
         3 . The reinforcing tape ( 1 ) as claimed in  claim 1 , wherein the two thermoplastic films ( 5 ,  6 ) are bonded together along the edges ( 8 ) of the tape ( 1 ).  
     
     
         4 . The reinforcing tape ( 1 ) as claimed in  claim 3 , wherein the ply of longitudinal yarns is capable of sliding inside the sheath formed by the two thermoplastic films ( 5 ,  6 ).  
     
     
         5 . The reinforcing tape ( 1 ) as claimed in  claim 1 , wherein each film ( 5 ,  6 ;  10 ;  15 ,  16 ) has ultraviolet radiation blocking properties.  
     
     
         6 . The reinforcing tape ( 1 ) as claimed in  claim 2 , wherein the longitudinal yarns are bound together by at least partly thermoplastic weft yarns.  
     
     
         7 . The reinforcing tape ( 1 ) as claimed in  claim 6 , wherein the thermoplastic of the weft yarns and the material of the films covering the ply ( 2 ) are similar.
