ABSTRACT IMPROVEMENTS IN OR RELATING TO SHEET MATERIAL A sheet material comprises at least three superposed layers (11, 12, 13, 14) each consisting of a plurality of strands (11a, 12a, 13a, 14a) disposed in a mass of adhesive so that individual strands of each layer adhere to one another and adjacent layers adhere to each other. Strands in adjacent layers are transversely, and prefer- ably perpendicularly, arranged. A preferred adhesive is curable polyvinyl chloride. Strands in non-adjacent layers may be substantially aligned or may be offset. Strands may have a non uniform or uniform spacing and may be of the same or differing decitex. Material is made by embedding strands in adhesive, placing layers so formed together and thereafter curing the adhesive. The material has greater tear strength in at least one direction than conventional plastics coated woven material having the same yarn content.
