Study on the Mechanical and Anticorrosion Performance of Unsaturated Polyester Resin(UPR)

A series of UPR samples were prepared based on orthogonal experimental design.The tensile properties including strength,elongation and elastic modulus were obtained by mechanical measurement.The tensile fracture morphology of the sample was analyzed by scanning electron microscopy(SEM),showing a feature of brittle fracture.Furthermore,corrosion experiments showed that the alkaline solution played an aggressive role for the materials.As the concentration of alkaline solution increased,the corrosive effect was enhanced.The permeability was characterized by corrosion test,and the penetration process of the sample could be described by Fick's Law.
