Mechanical properties of polyester resins in saline water environments

By evaluating the behavior of unsaturated polyester used in marine environments at room temperature, it is possible to determine its degradation using mechanical characterization parameters. There is a considerable decrease in its mechanical resistance due to the degradation effects. It must also be taken into account that the curing rate of a thermoset resin is one of the most important parameters in its behavior. This study will examine the correlation between the amount of water absorbed at room temperature, the curing rate, and the loss of mechanical properties.
