Abstract

A sail includes at least two layers of durable sailcloth material (e.g., Mylar), a scrim of load bearing yarns arranged in predetermined load path orientations, and at least one heat-activated adhesive layer securing the layers of material to the scrim, such that the scrim is positioned between the layers of material. At least one of the layers of material includes visible content on an outside surface thereof. The visible content is preferably applied to the outside surface(s) of the layer(s) of material using dye sublimation to provide durable imaging. An opaque layer may be optionally included between the two outer layers of material to prevent the passage of light through the sail. Alternatively, the adhesive layer(s) may be dyed or otherwise colored to effectuate an opaque layer. The sail is preferably manufactured using a high temperature, vacuum lamination process to mitigate the quantity of voids between the layers of material.

Claims

1. A method for fabricating at least part of a sailboat sail, the method comprising:

providing a first layer of a durable sailcloth material having a first side and an opposing second side, the first layer of material including first dye sublimated, visible content on the first side thereof;

disposing a first heat-activatable adhesive layer onto the second side of the first layer of material;

positioning the first layer of material on a support structure with the first adhesive layer facing upwards;

positioning a plurality of load bearing yarns upon the first adhesive layer in predetermined load path orientations;

providing a second layer of the durable sailcloth material having a first side and an opposing second side;

providing a second heat-activatable adhesive layer;

positioning the second layer of material upon the first layer of material such the second adhesive layer is positioned between the first side of the second layer of material and the plurality of load bearing yarns, wherein at least the first layer of material, the first adhesive layer, the plurality of load bearing yarns, the second layer of material, and the second adhesive layer form a sail arrangement;

positioning the sail arrangement into a vacuum; and

applying appropriate heat and pressure to the sail arrangement while the sail arrangement is in the vacuum to activate at least the first and second adhesive layers and to mitigate a quantity of voids between the first layer of material and the second layer of material.

2. The method of claim 1, further comprising:

positioning an opaque layer between the second adhesive layer and the first side of the second layer of material; and

providing a third heat-activatable adhesive layer between the opaque layer and the first side of the second layer of material,

wherein at least the first layer of material, the first adhesive layer, the plurality of load bearing yarns, the second layer of material, the second adhesive layer, the opaque layer, and the third adhesive layer form the sail arrangement.

3. The method of claim 1, wherein providing a second heat-activatable adhesive layer comprises:

disposing the second adhesive layer on the first side of the second layer of material.

4. A sailboat sail formed by a process comprising:

providing a first layer of a durable sailcloth material having a first side and an opposing second side, the first layer of material including first dye sublimated, visible content on the first side thereof;

disposing a first heat-activatable adhesive layer onto the second side of the first layer of material;

positioning the first layer of material on a support structure with the first adhesive layer facing upwards;

positioning a plurality of load bearing yarns upon the first adhesive layer in predetermined load path orientations;

providing a second layer of the durable sailcloth material having a first side and an opposing second side;

providing a second heat-activatable adhesive layer;

positioning the second layer of material upon the first layer of material such the second adhesive layer is positioned between the first side of the second layer of material and the plurality of load bearing yarns, wherein at least the first layer of material, the first adhesive layer, the plurality of load bearing yarns, the second layer of material, and the second adhesive layer form a sail arrangement;

positioning the sail arrangement into a vacuum; and

applying appropriate heat and pressure to the sail arrangement while the sail arrangement is in the vacuum to activate at least the first and second adhesive layers and to mitigate a quantity of voids between the first layer of material and the second layer of material.

5. The sail of claim 4, wherein the first and second layers of material are white sheets of Mylar.

6. The sail of claim 4, further including an opaque layer positioned between the second adhesive layer and the second side of the second layer of material.

7. The sail of claim 4, wherein at least one of the first adhesive layer and the second adhesive layer is opaque.

8. The sail of claim 4, wherein the second layer of material includes second dye sublimated, visible content on the second side thereof.

9. A laminated sail comprising:

a first layer of a durable sailcloth material having a first side and an opposing second side, the first layer of material including first dye sublimated, visible content on the first side thereof;

a second layer of the durable sailcloth material having a first side and an opposing second side;

a plurality of load bearing yarns arranged in predetermined load path orientations, wherein the plurality of load bearing yarns are positioned between the second side of the first layer of material and the first side of the second layer of material; and

at least one heat-activated adhesive layer securing the second side of the first layer of material, the first side of the second layer of material, and the plurality of load bearing yarns.

10. The sail of claim 9, wherein the second layer of material includes second dye sublimated, visible content on the second side thereof.

11. The sail of claim 9, further comprising:

at least one opaque layer positioned between the second side of the first layer of material and the first side of the second layer of material.

12. The sail of claim 9, wherein the at least one adhesive layer is opaque.

13. The sail of claim 9, wherein the first and second layers of material are sheets of Mylar.

14. The sail of claim 9, wherein the visible content includes at least one of textual informational matter, images, logos, slogans, and photographs.

15. The sail of claim 9, wherein the first and second layers of material are white.
