Abstract :This review summarizes current research examining the corrosion resistance, aging behavior, and mechanical properties of basalt fiber-reinforced polymer (BFTP) composites in marine applications. Naturally derived basalt fiber offers a strong alternative to glass and carbon fibers thanks to its high strength, thermal/chemical stability, low cost, and environmentally friendly structure. Findings indicate that BFTP composites exhibit high corrosion resistance, particularly in challenging environments such as acidic and seawater, and offer superior performance to vinylester resin systems. Surface treatments with silane, zircon, nanotubes, and metal additives also significantly enhance mechanical and corrosion resistance. BFTP composites, which have proven successful in marine hulls, propellers, and structural components, stand out for their low water absorption, high tensile/flexural strength, good fatigue resistance, and high-temperature resistance. Life cycle analyses indicate that they offer a lower carbon footprint compared to glass fiber composites. These properties make BFTP composites a sustainable and cost-effective alternative material for the maritime industry.
