ABSTRACT:
Unique PTFE fabric and laminate structures, and methods for making the same, are described. Particularly, the invention comprises a laminate of a fabric comprising a plurality of PTFE fibers overlapping at intersections, wherein at least a portion of the intersections have PTFE masses extending from at least one of the overlapping PTFE fibers, and which lock the overlapping PTFE fibers together, bonded to a membrane by at least said PTFE masses. Such reinforced membranes exhibit exceptionally high bond strength, a particularly valuable attribute in applications in which durability is important.
