Recently, carbon fiber composite reinforcement bars developed and produced by Sinopec Shanghai Petrochemical's Advanced Materials Innovation Research Institute have been successfully applied in the company's seawall safety hazard remediation project, following formwork processing and concrete pouring. This marks the first use of Shanghai Petrochemical's carbon fiber in seawall engineering, with a total of 1,250 meters of composite reinforcement bars deployed, significantly advancing the material's adoption in civil engineering.
The carbon fiber composite reinforcement bars, serving as construction raw materials, offer lightweight, high-strength, and corrosion-resistant properties. Their strength is 8–15 times that of conventional steel, while their density is only one-fifth of steel, delivering ultra-high specific strength and modulus. In practical applications, these bars effectively address issues such as rust and aging caused by seawater infiltration and harsh weather conditions.
Additionally, lifecycle assessments show that using carbon fiber composite reinforcement bars not only reduces energy consumption and carbon emissions but also cuts construction costs by over 20%, yielding notable environmental and economic benefits.
