抄録

We have studied the variation in tensile strength (σ_b), fracture strain (ε_f) and Young modulus (dσ/dε) of low voltage electron beam irradiation (HLEBI) on powdered ultra-high molecular weight-polyethylene from 0.043 to 0.43 MGy prior to sintering. The low dose of 0.043 MGy-HLEBI enhanced the σ_b, ε_f and dσ/dε, as well as increased the crystallinity ratio from 37 to 46% evaluated by differential scanning calorimetry (DSC). An additional dose apparently decreased the σ_b and ε_f, 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.
