enhance the corrosion resistance of underground petroleum tanks with the use of fiberglass-reinforced composite

In the present study, attempts are made to enhance the corrosion resistance in underground storage tanks. for this purpose glass fiber reinforced unsaturated polyester was used to coat the underground storage tank. the coating was applied by the hand layup technique. multiple layers of glass fiber reinforced coating were applied, with the matrix composition of 97% polyester, 2% hardener, and 1% cobalt as an accelerator. better corrosion resistance was observed when tested for the corrosion activity of the reinforcing steel with applied coating. it also provides better mechanical properties. for impact energy, the izod test was performed. the mechanical properties and corrosion resistance were increased as increasing the fiber layers in the composite. this research is very helpful for future use as it provides a more cost-effective and better mechanical properties solution for the coating of the underground storage tank.
