In this article, we discuss the radiation effects and ethylene‐vinyl acetate (EVA) as compatibilizing agent on waste polyethylene (WPE)/virgin polyethylene (VPE), 80/20 wt%, reinforced by Kevlar fiber (Aramid). Hence, by melt mixing the compatibility between WPE and VPE will be performed by adding 10 phr fixed weight of EVA. After that various weights of Kevlar fiber at phr 1.5, 2.5, and 3.5 were reinforced into prepared polymer blend. The composites mechanical properties and the thermal stability were predicted. Furthermore, infrared and X‐ray diffraction used to characterize the composites structure. Improvements of both tensile strength and elastic modulus of prepared composites at 1.5 phr of Kevlar was observed and decreased in their values were noticed after that. Also, thermal stability has been enhanced with EVA and Kevlar fiber. Remarked improvements in studied parameters were generally determined by formation of crosslinking networks via gamma irradiation.

基于废聚乙烯的凯夫拉尔纤维增强复合材料：乙烯-乙酸乙烯酯和γ辐射的影响

在本文中，我们讨论了用芳纶纤维（芳纶）增强的80/20 wt％废聚乙烯（WPE）/原生聚乙烯（VPE）的辐射效应和乙烯-醋酸乙烯酯（EVA）作为增容剂。因此，通过熔融混合，WPE和VPE之间的相容性将通过添加10 phr固定重量的EVA来实现。之后，将各种重量的phr 1.5、2.5和3.5的凯夫拉尔纤维增强到制备的聚合物共混物中。预测了复合材料的机械性能和热稳定性。此外，红外和X射线衍射用于表征复合材料的结构。观察到在1.5phr的Kevlar下，所制备的复合材料的拉伸强度和弹性模量均得到改善，然后发现其值降低。而且，EVA和芳纶纤维提高了热稳定性。
