Resumen

Abstract: The compressive and tensile properties of polylactic acid (PLA), polyethylene terephthalate glycol (PETG), polycarbonate (PC), and acrylonitrile styrene acrylate (ASA) were evaluated. In addition, changes in the tensile properties because of the degradability of the polymers, under simulated marine environment conditions, were studied. Among the non-degraded materials, it was found that PC and PLA are the ones with the highest resistance to compression and tension. After the degradation, it was found that PC and PETG have better mechanical properties of toughness and resistance; therefore, among the polymers studied, they are the more appropriate materials for applications in marine environment conditions.
