Abstract

The deformation properties of epoxy polymers during natural aging in a tepid climate were studied by performing quantitative fractography and investigating the relief of fracture surfaces of epoxy polymers by mechanical tensile testing. The brightness in fracture micrographs correlated with the elongation at fracture.
