Abstract
A composite structural panel is provided. The panel comprises a top reinforced fiber layer, a top infusion medium layer, a core, a bottom infusion medium layer, and a bottom reinforced fiber layer. The composite structural panel is infused with a potting material, preferably an epoxy resin, that extends throughout the composite structural panel to provide composite action. The wood core comprises wood beam elements aligned in the longitudinal direction relative to the steel beams or girders of a supporting frame. Mechanical and chemical means are utilized to connect the composite structural panel to the supporting frame.
Claims13
A structural assembly for a bridge, the assembly comprising:
- a support frame including a first girder and second girder substantially aligned with a longitudinal direction, the first girder and the second girder being laterally spaced apart from each other;
- and
- a bridge deck including a vacuum infused composite structural panel supported by and extending between the first girder and the second girder, the panel including:
- (a) a bottom and a top reinforced fibre layer;
- (b) a bottom and a top infusion medium layer;
- (c) a wood core;
- and
- (d) a potting material;
- wherein the bottom reinforced fibre layer is adapted to engage the entire surface of the bottom infusion medium layer, the bottom infusion medium layer is adapted to engage the entire surface of the wood core, the wood core is adapted to engage a top infusion medium layer, the top infusion medium layer is adapted to engage the top reinforced fibre layer, and the potting material impregnates, surrounds and encases the reinforced fibre layers, the infusion medium layers, and the wood core;
- and
- wherein the wood core comprises a plurality of wood beam elements wherein the wood beam elements are adapted adjacently and engagingly to each other and are aligned parallel to each other, and, each wood beam element has a longitudinal axis that runs parallel to the longitudinal direction of the first girder and the second girder.
