Environmental Effects on Mechanical Properties of Glass-Epoxy Composites

This study presents the effects of seawater and distilled water immersion time periods on mechanical properties of unidirectional glass reinforced epoxy composites. Tension, compression, and shear test specimens exposed to seawater and distilled water were prepared according to ASTM standards. After tests, SEM imaging of fracture surface of specimens was made. Results showed that seawater and distilled water immersion time affects significantly mechanical properties and strength values of glass-epoxy composites.
