Glass fiber composite materials have been well known in certain maritime applications for a long time, being used in several applications in different fields. The characteristics of Glass fiber-reinforced Polyester (GFRP) depend on the contained fibers, the matrix used, and the fiber-to-total volume ratio. GFRP is a polymer material used in various fields; it is generally preferred for its ease of installation and its very long lifespan, even in the presence of aggressive fluids. The aim of this research is to study the evolution of mechanical properties (tensile strength and flexural strength) of GFRP preserved in different environments such as open air (control), drinking water, and seawater (harsh environment). Additionally, tests on GFRP are conducted through chemical characterization studies or SEM observation of the resin. Lastly, GFRP is considered to be chemically stable for a conservation period of one year in seawater. Finally, despite the conservation of GFRP for a year in a humid and sulphate environment, we note that the connection between the fibers and the matrix is in good condition, or the conservation environment has no influence on the GFRP composite.
