Quality control of carbon fiber in bridge reinforcement

Carbon fiber fabric have the advantages of stable structure, light weight, good cold resistance, corrosion resistance and heat resistance, and are widely used in pure tensile components. This is extremely relevant to its excellent strength and stiffness.

Steel beams strengthened with CFRP plates

In recent years, FRP materials, especially CFRP materials, have been widely used in civil engineering. Although not as widely used as reinforced concrete structures, CFRP reinforced steel structures have also begun to be applied to bridges and housing construction.

Advanced composites in bridge construction and repair

The advanced composite materials have the advantages of corrosion resistance, light weight (1/5 to 1/4 of the bulk density of steel), high strength (the strength is higher than the high strength steel wire or the equivalent).

Carbon fiber fabric reinforced brick masonry chimney

The cracks are first treated by grouting and sealing, so as to restore the integrity of cracked masonry, and then reinforce the treatment with carbon fiber fabric. After strengthening, it has been used for more than a year, and no new cracks have been found
