Process for fabricating sails for wind-powered devices and wind propulsion purposes by bonding together the rigid and flexible parts of the sail such as widths of sail fabric, spindles, panels and reinforcing parts, using a structural adhesive which (a) has good surface bonding characteristics w.r.t. the materials of construction of the sail and (b) has sufficient cohesive strength to transmit mechanical forces between neighbouring components of the sail, characterised in that the adhesive joints are of low thickness and are formed parallel to the surface of the parts being bonded in overlapping joint zones between the component parts of the sail so that the adhesive can transmit all the mechanical forces circulating between the component parts and in the surface of the sail during normal use. USE/ADVANTAGE - The process allows sails of any size or shape to be fabricated for use in any wind propulsion application. The wholly bonded construction of the sail gives better transmission of the forces generated in the sail over the whole area and overcomes the distortion with ageing which can occur with stitched or rivetted sails, so that the sail retains its shape and fills properly throughout its life. |
