1. An open structure composite member comprised of a plurality of jacketed yarns, each comprised of a plurality of tows pre-impregnated with resin and defining a core formed from at least twenty thousand (20,000) axially aligned filaments, the tows packed within a jacket, wherein the plurality of ja
1. An open structure composite member comprised of a plurality of jacketed yarns, each comprised of a plurality of tows pre-impregnated with resin and defining a core formed from at least twenty thousand (20,000) axially aligned filaments, the tows packed within a jacket, wherein the plurality of jacketed yarns are combined and cured to form an open structure composite member, and wherein the open structure composite member is formed at a rate of at least one meter per minute. 2. The composite member of claim 1 further comprising jackets formed from tows pre-impregnated with resin. 3. The composite member of claim 1 whereby the jackets are formed from a material selected from the group consisting of aramids, polyethylene, nylon, polyester, polyolefin, and liquid crystal polymer. 4. The composite member of claim 1 whereby the jackets are formed from one of braiding, yarn wrapping, or thermoplastic extrusion. 5. The composite member of claim 1 further comprising axially aligned filaments selected from the group consisting of carbon fiber, para-aramid, liquid crystal polymer, and glass. 6. The composite member of claim 1 comprising jacketed yarns defining a braiding architecture selected from the group consisting of diamond, twill, hercules, biaxial, triaxial, and true triaxial patterns. 7. An open structure composite member comprised of a plurality of jacketed yarns each comprised of a plurality of tows pre-impregnated with resin and defining a core formed from at least twenty thousand (20,000) axially aligned filaments, the tows hexagonally packed within a jacket, wherein the plurality of jacketed yarns are combined and cured to form an open structure composite member. 8. The composite member of claim 7 further comprising jackets formed from tows pre-impregnated with resin. 9. The composite member of claim 7 whereby the jackets are formed from a material selected from the group consisting of aramids, polyethylene, nylon, polyester, polyolefin, and liquid crystal polymer. 10. The composite member of claim 7 whereby the jackets are formed from one of braiding, yarn wrapping, or thermoplastic extrusion. 11. The composite member of claim 7 further comprising axially aligned filaments selected from the group consisting of carbon fiber, para-aramid, liquid crystal polymer, and glass. 12. The composite member of claim 7 comprising jacketed yarns defining a braiding architecture selected from the group consisting of diamond, twill, hercules, biaxial, triaxial, and true triaxial patterns. 13. A method of forming an open structure composite member comprising the steps of: providing a plurality of jacketed yarns each comprised of a plurality of tows pre-impregnated with resin and that define a core formed from at least twenty thousand (20,000) axially aligned filaments packed within a jacket;combining the plurality of jacketed yarns; andcuring the combined jacketed yarns to form an open structure composite member. 14. The method of claim 13 wherein providing a plurality of jacketed yarns includes providing jackets formed from tows pre-impregnated with resin. 15. The method of claim 13 wherein providing a plurality of jacketed yarns includes providing jackets formed from a material selected from the group consisting of aramids, polyethylene, nylon, polyester, polyolefin, and liquid crystal polymer. 16. The method of claim 13 further comprising the step of interlacing the open structure composite member with a yarn, the yarn oriented laterally within said open structure composite member. 17. The method of claim 13 further comprising the steps of: exuding resin from the plurality of pre-impregnated tows;mechanically interlocking the plurality of tows; andbonding the plurality of tows that contact the resin at a crossover joint. 18. The method of claim 14 further comprising the steps of: exuding resin from the plurality of pre-impregnated jackets;mechanically interlocking the plurality of jackets; andbonding the plurality of jackets that contact the resin at a crossover joint. 19. The method of claim 15 further comprising the steps of: partially melting the jackets; andbonding the jackets at a crossover joint. 20. The method of claim 13 further comprising the steps of: reinforcing the open structure composite member with a plurality of braided sleeves;infusing resin into the plurality of sleeves;adding resin at a crossover joint; andcuring the open structure composite member with a plurality of braided sleeves.
