Analysis of the compression behavior of an E-glass composite pipe after aging in water

E-glass-reinforced composite pipes are being increasingly used in petrochemical facilities. After years of contact with the fluid being transported, the mechanical integrity of the pipes can be compromised, and their failure mode can be altered. This work analyzes the effect of temperature and pressure on the compressive behavior of an E-glass pipe after exposure to water. The results indicate that temperature causes more damage than pressure on the mechanical response of the composite. A macroscopic damage parameter quantified the effect on the mechanical behavior of the composite. Surface gloss changes were also correlated with the effects caused by aging.
