ABSTRACT:
A multi-layer article of manufacture includes an intermediate layer of a water-swellable colloidal clay, such as bentonite, sandwiched between two layers of flexible sheet or fabric material wherein the two flexible layers of sheet or fabric material are structurally interconnected through the intermediate clay layer, such as by needle punching, after lubrication of the clay surface with a liquid, such as water, to interconnect fibers of one fabric layer to the other fabric layer at spaced locations over essentially the entire inner surface areas of both sheet or fabric material layers. In a preferred embodiment, a water-insoluble adhesive is applied to at least one of the fabric layers to lock the interconnecting fibers in place and substantially increase the structural integrity, particularly the shear strength, of the article.
