Abstract

Highlights: The effect of supercritical CO2 on corrosion behavior of FRP was investigated. The pitting and acid corrosion of FRP in medium containing supercritical CO2 was observed. The corrosion mechanism of FRP in medium containing supercritical CO2 was clearly statement as physical dissolution and hydrolysis reaction. Abstract: The effect of supercritical CO2 (sc-CO2 ) on corrosion behavior and mechanism of fiber reinforced pipe (FRP) in this work. The pitting corrosion occurs on the surface of matrix due to the dissolution by sc-CO2 . A minute change in the constitution of elements and functional groups are observed as well as atomic ratio of O to C, which increases from 37.23% to 42.43% after treatment. Furthermore, the stiffness of FRP decreases from 6455 N/m 2 to 6421 N/m 2 suffering from the corrosion of mixture containing sc-CO2 . The corrosion mechanism of FRP in sc-CO2 can be confirmed as physical dissolution and hydrolysis reaction.
