Abstract

Through summarizing and analyzing the physical corrosion theories of polymer, a theoretical model is constructed to depict the relationship between relaxation time with temperature, stress and humidity. The correlation between physical corrosion behavior and external factors is predicted from semi-experimental profile. In sequence, the morphology of polymer and fiber was investigated by the scanning electron microscopy (SEM) in comparison with that of nonimmersed samples. The dynamic mechanical thermal analysis (DMTA) methods were used to study the evolution of thermomechanical properties against immersed time. It is found that the glass transition temperature (T_g) and storage modulus were significantly reduced with immersion time increase. Then the hardness, tensile strength and bending strength of GFRP were tested by their corresponding mechanical measurements.
