Abstract

This paper presents the radiation stability behavior of polyamide composites containing rice husk ash as filler. Samples consisting of polyamide 6 and 0, 10, 20 and 30 % (w/w) filler were EB irradiated at following doses: 0, 100, 200, 600 and 1000 kGy. The evaluation of radiation stability was accomplished by FT-IR spectroscopy and chemiluminescence. The assessment on characteristic bands of amide group was studies during the thermal degradation. The spectral and chemiluminescence investigations allowed the evaluation of propitious contribution promoted by rice hush ash in polyamide 6 composites in relation with radiation stability of studied substrates..
