Abstract

The effect of gamma irradiation and aging on ultra high molecular weight polyethylene (UHMWPE) and the correlation between mechanical properties and oxidation were investigated. Microindentation testing was performed across cut blocks of standard GUR 1020 resins, which were subjected to different treatment including gamma irradiation and artificial aging. FTIR was used to calculate the oxidation indices at each microindent location and then correlated with the mechanical properties. High, linear correlations were found to exist between mechanical properties and oxidation.
