ABSTRACT:
A coated triaxial fabric, a process for its preparation and a laminated article prepared therefrom are provided. The coated fabric comprises a triaxial fabric, such as glass or polyester fibers, having a polymeric material impregnating and coating the fabric in an amount sufficient to set the yarn courses of the fabric where they cross one another and to give such a coated fabric superior isotropic tear resistance and strength (substantially uniform in all directions) when compared to a similarly constructed coated fabric prepared from a conventional biaxial fabric or a conventional bias ply construction. The coated fabric can be bonded to substrates such as metals and polymeric films.
