High performance fiber reinforced composite pultruded profile
Overview
High performance fiber reinforced composite pultruded profiles are composites made of fiber reinforced materials (such as glass fiber, carbon fiber, glass fiber - carbon fiber hybrid fiber, etc.) and resin matrix materials (such as epoxy resin, vinyl resin, unsaturated polyester resin, polyurethane resin, etc.) by pultrusion process. Compared with traditional building materials (such as steel and concrete), pultruded profiles have the advantages of light weight, high strength, corrosion resistance and low carbon.
Technical performance and indicator
(1) Excellent mechanical properties, the longitudinal tensile strength of glass fiber composite profiles can reach about 1800 MPa, the elastic modulus can reach about 65 GPa, the longitudinal tensile strength of carbon fiber composite profiles can reach about 2200 MPa, the elastic modulus can reach about 160 GPa;
(2) Light weight, the density of glass fiber composite profiles is about 2.0×103kg/m3, and the density of composite profiles is only 1/4 of that of steel;
(3) Strong corrosion resistance, composite profiles have strong environmental corrosion resistance, and have a longer maintenance cycle than metal, which reduces the maintenance cost of the whole life cycle of structures.
Technology readiness level
TRL9: Actual technology qualified through successful mission operations
Financial comparison
The life-cycle maintenance cost of pultruded profiles is lower than that of similar steel structures and concrete structures.
Application areas
It can be used in the field of construction engineering, and can also be expanded in the field of subway, urban pipe corridor and prefabricated buildings, such as high-rise building external frame beams, urban rail transit sound barriers, photovoltaic carports, container houses, etc.
