In this paper, the corrosion behavior and wear performance of basalt/epoxy composites exposed to salt-water were experimentally studied. Besides, the impact of graphene nanoplatelet modification of epoxy matrix on the water absorption and wear performance of the multi-scale composite were also investigated. Results showed that GNPs modification reduced the water absorption by 50% and the coefficient of friction by 19% with less reduction in tensile strength and modulus of elasticity at the end of the 6th month. A detailed water absorption/wear/corrosion mechanism is given as supported by a systematic characterization.

GNPs增强的海上应用玄武岩-环氧树脂多尺度复合材料的长期盐水耐久性

本文通过实验研究了玄武岩/环氧复合材料在盐水中的腐蚀行为和磨损性能。此外，还研究了石墨烯纳米片修饰环氧基质对多尺度复合材料的吸水率和磨损性能的影响。结果表明，在第6个月末，GNPs改性使吸水率降低了50％，摩擦系数降低了19％，而抗拉强度和弹性模量降低了。详细的吸水/磨损/腐蚀机理在系统表征的基础上给出。
