摘要 本文探讨了在模拟海水环境下GFRP(Glass Fiber Reinforced Plastic)的腐蚀的规律和机理,着重于温度、海水浓度和时间等因素对材料性能的影响。采用SEM分析方法,观察GFRP试样的宏观和微观形貌腐蚀前后的变化情况;通过力学试验,探讨了GFRP的力学性能演变规律;通过不同海水浓度腐蚀试验,探讨了海水浓度对GFRP耐腐蚀性能的影响规律。经过一年的静水浸泡试验结果表明,渗透和扩散是腐蚀的基本动力;温度升高,盐度增大,试样渗透率上升,力学性能下降;并在试验数据的基础上,建立了腐蚀经验模型及腐蚀评价标准。 In the present study, GFRP (Glass Fiber Reinforced Plastic) samples were aged in several conditions that simulate common marine environments for researching its erosion regulations and rules, the concern of issue addressed here was temperature, salt concentration, time and its impact on the corrosion resistance of GFRP. Though SEM method, the microstructure and macrostructure of samples which before and after the erosion were observed; by tensile and flexttral testing, the change rules of GFRP' s mechanical properties were obtained. Samples aged in the solutions which has different temperature and salt concentration for one year, the results indicate that the infiltration and pervasion are the basic power of erosion; with the elevating temperature and salt concentration, the permeability ratio of specimen is increased, while mechanical properties are decreased; experimental models and the standards about erosion degree have established based on the experiential data.
