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. |
