Abstract: Because of its advantages of structure designability, light weight, high strength, corrosion resistance and excellent processing property, the FRP material shows broad application prospect in bridge engineering. Though the research of the structural design for a large cross-section FRP pultrusion profiles, combined with the large crosssection FRP pultrusion profiles of the raw materials selection, layer design, forming process parameters and the postprocessing of adhesive process are discussed, the mechanical properties of the same furnace sample material were tested, the feasibility of using large cross-section FRP pultrusion profiles as bridge panel was verifred.

Key words: bridge, FRP pultrusion profiles, structural design, type testing
