Moisture sorption–desorption–resorption characteristics and its effect on the mechanical behavior of the epoxy system

Thermosetting epoxy resins are attractive materials for many engineering applications, as they are low in density, with excellent mechanical properties and easily fabricated by processes such as injection molding, extrusion and vacuum forming. However, the hostile hygrothermal environment can degrade the epoxy system. In this study, moisture sorption–desorption–resorption characteristics of the DGEBA/DDA epoxy system have been investigated by...
