Résumé en anglais : [en]

We have studied the variation in tensile strength (sigma(b)), fracture strain (epsilon(f)) and Young modulus (d sigma/d epsilon) of low voltage electron beam irradiation (HLEBI) on powdered ultra-high molecular weight-polyethylene ...

The low dose of 0.043 MGy-HLEBI enhanced the ob, epsilon(f) and d sigma/d epsilon, as well as increased the crystallinity ratio from 37 to 46% evaluated by differential scanning calorimetry (DSC). An additional dose apparently decreased the ab and ef, as well as the melting point from approximately 412 to 406 K and the crystallinity ratio from 46 to 43% for 0.043 to 0.43 MGy, respectively. Irradiation induces two competitive mechanisms, namely (i) the scission of chains and (ii) the crosslinking of chains. The discussion is focused on these mechanisms.Lire moins >
