Nanohardness of electron beam irradiated polyamide 11

Abstract

The submitted paper presents the assessment of mechanical properties of the surface layer of modified polyamide 11. Hard surface layer was made using the technology of radiation crosslinking, which enables modification of polymer materials and hence the change of their end-use properties. The process of mechanical stress is applied by nanohardness test. The surface layer of polymer material such as polyamide 11 is modified by β - radiation. After the polyamide 11 is subjected to radiation, changes of the surface layer at applied load are observed. Material properties of the created surface layer are measured by nanohardness test using the DSI method (Depth Sensing Indentation).
