The main objective of this work is to determine the influence of electron beam irradiation on thermal and mechanical properties
of most promising bio-based and biodegradable Poly (lactic acid) (PLA) based blend-composites. The PLA/PEGM blend is
prepared, to reduce the brittleness and improve the toughness of PLA, by using twin-screw Micro compounder. However, the heat
deflection temperature (HDT) and other tensile properties were reduced. The HBN has been incorporated as part per hundred i.e.
5 phr and 10phr to improve the HDT of prepared blend. The prepared specimens of blend and blend-composites were irradiated to
high energy (4.5 MeV) electron beam (E-beam) at different radiation doses to introduce the cross linking among the polymer chains
and uniform dispersion of HBN particles in the PLA/PEGM/HBN blend-composites. The further improvements in the notched
impact strength and HDT have been achieved in the case of PLA/PEGM/HBN blend-composites. The irradiated PLA/PEGM/HBN
5phr blend composite shows high notched impact strength and HDT as compared to other Unirradiated and E-beam irradiated
blend and blend-composites. The improvements in the yield strength and tensile modulus have also been noticed in case of E-beam
irradiated PLA/PEGM/HBN blend-composites as compared to Unirradiated blend-composites.
