A thermoplastic composite is formed of a plurality of elongate elements (14) which may be braided together, each element comprising a thermoplastic polymer base having at least one thermoplastic surface polymeric layer bonded to the polymer base. The surface layer has a softening temperature lower than that of the polymer and, at least at the outer surface of the composite, the surface layer of each element is fused with the surface layer of adjacent elements to provide a sealed structure. The composite may be in the form of a yarn, tape, cord (10), string, rope, twine or the like, and may be arranged in the form of a desired structure; for example the elements may have been braided into a suitable yarn and then knotted into a net structure, eg a fishing net. <IMAGE> |
