摘要: A composite structural panel for use in bridge structures, and method of manufacturing same, comprises a top panel and a bottom panel separated by and attached to at least one, but preferably a plurality, of structural composite preforms which may be fabricated by a continuous manufacturing process and may be saturated by resin using a continuous wetting process. The composite preforms may take any cross-sectional shape but are preferably trapezoidal. The top and bottom panels may be fabricated from a plurality of layers of woven fabric layers and non-woven fabric layers which are saturated with a resin that is subsequently cured using cure processes known in the art. The composite structural panel of the invention is usable as a flat structural member for use as bridge decking, ramps, trestles, and any application requiring a structural panel.

摘要: During bridge construction, a form at the upper, outer edge of a bridge's outer girder, upper flange retains concrete slurry poured on the bridge's deck. The girder is cast with extended upper flanges, and the form is precast integrally with the flange. The improved girder may eliminate the need for a construction worker walkway.
