PT Journal AU Greskovic, F Dulebova, L TI The Effect of Radiation on Mechanical Properties of Parts Made of Polymer Composites SO Acta Mechanica Slovaca PY 2016 BP 6 EP 9 VL 20 IS 1 DI 10.21496/ams.2016.001 DE polypropylene; irradiation; radiation dose; mechanical properties AB The article deals by the application area of radiation crosslinking of plastics, which follows after the injection moulding. The main objective of the presented article is the research of influence irradiation dosage on mechanical properties of materials: PP unfilled and PP filled by 25% of glass fibres. Mechanical properties (tensile strength, modulus, bending stress and impact strength by Charpy test) were examined in dependence on absorbed dose of the β electron radiation on various conditions and were compared with non-irradiated samples.
