Abstract |
The preliminary results of defect analysis using SRIM computer code in UHMW polyethylene and its composites with Martian Regolith (MR) subjected to irradiation by 600 MeV/u 56Fe+-ions were previously reported. A more detailed and comprehensive analysis of SRIM is presented here along with a comparative study of nano-porosity obtained from the Positron Annihilation Lifetime Spectroscopy (PALS). The differences observed in the nano-porous free volume from PALS and in the flexural stress are explained in terms of the variations in vacancy concentrations, dissipated energy density, ratio between H-vacancies to C-vacancies, and their influence on chemical transformations. Keywords - Ion-irradiation, Polyethylene Composites, Martian Regolith, SIRM Analysis. | |||||||||
