Advancing Marine Infrastructure: Integration of Advanced Composite Materials with Concrete

This paper delves into the transformative potential of integrating advanced composite materials withconcrete in marine engineering, supported by empirical data and numerical analysis. It explores howmaterials such as carbon fiber reinforced polymers (CFRP) can enhance concrete structures. Thecompressive strength of concrete, typically ranging from ۲۰ to ۴۰ MPa, contrasts with its lower tensilestrength of ۱ to ۵ MPa. Statistical analysis reveals that while initial costs for concrete reinforced withadvanced composites may be $۱۰۰ higher per cubic meter, lifecycle analysis indicates reduced maintenancecosts and extended service life, resulting in significant long-term savings. Numerical simulations predictstructural responses of concrete bridges reinforced with CFRP, showcasing maximum stresses ranging from۶۰ to ۱۰۰ MPa under varied loading conditions. Optimization processes demonstrate enhancements incomposite material properties, such as increasing tensile strength from ۲۵۰ to ۳۰۰ MPa while reducingdensity from ۱۵۰۰ to ۱۴۰۰ kg/m³. This paper underscores the economic feasibility and sustainability ofintegrating advanced composites with concrete, paving the way for resilient and sustainable marineinfrastructure globally.
