<p>A canvas with a laminated structure which is designed for the production of sails for wind-driven craft, has a core ( 250 ) which includes each sealing leaf of the canvas, and at least two layers ( 203, 205 ) of structural fibres ( 503, 505 ) which all extend on the exterior of the core ( 250 ), with at least one layer ( 203, 205 ) on each side of the core ( 250 ). In the canvas, each sealing leaf includes at least one continuous film ( 220 ) of polymer material, and the structural fibres serve the purpose of reinforcing the resistance of the canvas in relation to mechanical loads which can be applied to the canvas. The invention also extends to sails which are at least partially produced from a material of this type.</p> |
