Study of Environmental Corrosion Behavior and Mechanism of the Carbon/Epoxy Composite

Abstract:

Article Preview

Polymer composite materials, as advanced materials have been widely used worldwide, especially in the advanced technology field, due to their outstanding properties. Nowadays, a growing attention has been paid to the environmental corrosion failure of composites. Since it is environment related corrosion, the test parameters selected were temperature, humidity and ultraviolet. Among all the environmental factors, the temperature, especially acts with humidity, is the most affective factor. In order to get detailed information, the weight gains of the samples tested were measured regularly during the test. By the comparison, it can be seen that the water absorption rate had been affected remarkably due to the salt existence or the temperature change. The observation of the sample microstructure showed that there were many holes on the surface, indicating that the surface of the samples was destroyed by the test, and that there were some interactions between the surface layer and the absorbed component. It is that only the effect of temperature and humidity was discussed in this paper, the effect of the rest environmental factors will be discussed in following paper.
