Sailboat rigging system and method of manufacture
The invention is a sailboat rigging system and method for forming same. It is formed from a plurality of resin prepreg high strength fiber strands, tows or roving. The fiber are laid out in a preferred rigging configuration with the fiber strands, tows or roving being placed under generally equal tension. The resin in the prepreg fibers bonds the fiber strands, tows or roving to consolidate them together substantially without open spaces therebetween. If desired, the fiber strands, tows or roving can be branched out at branching points to provide for continuous rigging, and selective fibers can be dropped at various sections of the rigging for weight savings.
1. A sailboat rigging system comprising:
elongate rigging comprising a plurality of high strength fiber strands, tows or roving, and resin, wherein the fiber strands, tows or roving are laid out in a preferred rigging configuration with the fiber strands, tows or roving being placed under generally equal tension, and with the resin cured together with fiber strands, tows or roving to consolidate them together substantially without open spaces therebetween, wherein the preferred rigging configuration includes a branching region having an upper region and a lower region, with a plurality of elongate branching sections extending into the upper region of the branching region and merging into a single elongate section which extends downwardly from the lower region of the branching region, and with the fiber strands, tows or roving in the branching region being under generally equal tension.
2. The sailboat rigging system of claim 1 , wherein the resin is thermosetting polymer resin and/or thermoplastic resin.
3. The composite rigging system of claim 2 , wherein the thermosetting and/or thermoplastic polymer resin includes a UV protective additive to enhance weathering resistance.
4. The sailboat rigging system of claim 1 , wherein the high strength fiber strands, tows, or roving are initially pre-impregnated with the resin in an uncured form.
5. The sailboat rigging system of claim 1 , wherein the resin comprises epoxy.
6. The sailboat rigging system of claim 1 , wherein the high strength fiber strands are selected from the group consisting of carbon fibers, aramid type fibers and/or PBO fibers.
7. The sailboat rigging system of claim 1 , further comprising a terminating cone at least at one end of the elongate rigging into which the fiber strands, tows or roving are consolidated along with a mix of additional resin and short fibers.
8. The sailboat rigging system of claim 7 , wherein the resin is pre-impregnated in the high strength fiber strands, tows or roving, and wherein when the resin is thermosetting resin, is co-cured, and wherein when the resin is thermoplastic resin, is co-processed, at the same time with the additional termination resin and short fiber mix, thereby enhancing adhesive bonding of the terminating cone and the fibers strands, tows or roving by eliminating secondary bonding.
9. The sailboat rigging system of claim 1 , wherein a sum of the number of fiber strands, tows or roving in the plurality of elongate sections that extend from the upper area of the branching region is greater than the number of fiber strands, tows or roving in the single elongate section that extends from the lower region of the branching region, with a difference between the number of fiber strands, tows or roving in the plurality of elongate sections that extend from the upper area and the number of fiber strands, tows or roving in the single elongate section be accommodated by dropping off fiber strands, tows or roving at a drop-off region on the single elongate section.
10. The sailboat rigging system of claim 9 , further comprising over-wrapping material that covers the consolidated fiber strands, tows or roving and resin in the branching region and the drop-off region.
11. A sailboat rigging system comprising:
elongate rigging comprising a plurality of ends and a plurality of high strength fiber strands, tows or roving, and uncured thermosetting polymer resin and/or thermoplastic resin, wherein the fiber strands, tows or roving are laid out in a preferred rigging configuration with the fiber strands, tows or roving being placed under generally equal tension, and with the resin cured together with fiber strands, tows or roving to consolidate them together substantially without spaces therebetween, wherein the preferred rigging configuration includes a branching region having an upper region and a lower region, with a plurality of elongate branching sections extending into the upper region of the branching region and merging into a single elongate section which extends downwardly from the lower region of the branching region, and with the fiber strands, tows or roving in the branching region being under generally equal tension; and
a terminating cone at least at one end of the elongate rigging into which the fiber strands, tows or roving are consolidated along with additional resin.
12. The sailboat rigging system of claim 11 , wherein a sum of the number of fiber strands, tows or roving in the plurality of elongate sections that extend from the upper area of the branching region is greater than the number of fiber strands, tows or roving in the single elongate section that extends from the lower region of the branching region, with a difference between the number of fiber strands, tows or roving in the plurality of elongate sections that extend from the upper area and the number of fiber strands, tows or roving in the single elongate section accomplished by dropping off fiber strands, tows or roving at a drop-off region on the single elongate section.
