The filament wound process for the manufacture of a bridge web was demonstrated to be both feasible and practical. This program identified some process modifications that are required for low cost production. The modified process will retain the attractive features of the wound W process, but will greatly reduce tooling costs and improve producibility resulting in lower labor costs. The winding angle may be modified from 45 degrees 45 to 50 degrees to improve the winding pattern without impacting the structural integrity, but should be left at 45 degrees for maximum strength at minimum thickness. The design requirements for edge filler are met by the syntactic foam which Fiber Science used. This foam reduced the weight by an average of eight pounds per web over the weight of solid epoxy resin edge filler. Tests of the syntactic foam compressive strength, although high enough to meet design requirements, were not as high as anticipated.
