Corrosion Mechanism And Performance Evolution Rule Of Gfrc Under Marine Environment

The glass fiber reinforced plastic compound material (FRP) by its outstanding resists corrosion the performance gradually is received by our country and the world scientist's value in the sea domain application,but to the high polymer material corrosion question research is inferior to the metal material corrosion question studies that thorough and widespread,and lack of corrode data the FRP in the field of marine applications.Through summing up and sorting vinyl resins in the marine environment , using materials corrode basic theories about the FRP in the environment in the form of corrosion and corrosion of these forms of the course material damage; testing and simulating environment through accelerated testing to recognize the law and corruption mechanisms, focusing on temperature, humidity, salt, and other factors on the materials to the corrosive effects of research, for both single-factor (temperature, salinity, humidity) simulation acceleration experiments, but for many factors (stress + humidity) accelerated simulation experiments identify mechanisms and the role of its single synergy effects; materials damaged by the situation, the physical-chemical properties, micro-structural changes estimate FRP's performance, a comprehensive study in the corrosive water course on corrosion mechanisms, clear picture of the mechanics of materials in the course of testing the performance changes; in the accumulation of data corruption on the basis of a reliable water FRP in the context of corrosion evaluation of technical standards for corrosion testing, materials and engineering design provide the basis and norms; According to corrosion dynamics equation and environmental factors affecting experience equation,appropriate selection and simplify parameter to build a projected life expectancy of ageing mathematical models and certification; address the basic problem is water environment science fibre glass corrosion universality, the main environmental impact factors, rapid corrosion mechanisms and the evolution of material performance.Test results show that vinyl resins mainly eroded by the humidity,swell,stress and chemical in the marine environment. Moisture infiltration followed Fick No1 law, and only with the environmental humidity and polymer structure,...
