Craze initiation, physical aging effect

Craze Initiation and FaUure in Glassy Poly(ethylene Terephthalate) The Effects of Physical Aging with and Without Exposure to Chemical Environments... [Pg.242]

In the work reported here, changes in molecular free volume and tensile properties of PET have been followed as a function of physical aging. Positron annihilation lifetime spectroscopy (PALS) was used to measure free volume. The effect of physical aging on the competition between yielding and crazing without exposure to corrosive chemical environments was also investigated. Finally, the effect of physical aging on craze initiation at low strains due to exposure to a variety of solvents was determined. [Pg.243]
