The purpose of this study was to investigate the effect of carbon fiber (CF) and electron‐beam (EB) radiation on high‐temperature mechanical properties of ethylene‐vinyl acetate (EVA). Polymer composites were prepared by mixing on a two‐roll mill. After compression molding, the samples were irradiated between 60 and 180 kGy, and dynamic mechanical analysis (DMA) was used to characterize physical properties. The effects of filler content and radiation level on the mechanical properties of EVA/CF were evaluated. The shear stress and modulus were observed to increase with increasing of the filler level. However, there was a dramatic decrease in creep compliance. It was also shown that introduction of irradiation on EVA composite increases the shear stress and the real part of the dynamic shear modulus G' due to the increase in molecular weight and cross‐linking of the polymer after irradiation.

电子束辐照对醋酸乙烯/碳纤维复合材料高温力学性能的影响

这项研究的目的是研究碳纤维（CF）和电子束（EB）辐射对乙烯-醋酸乙烯酯（EVA）高温机械性能的影响。聚合物复合材料是通过在两辊磨机上混合制备的。压缩成型后，将样品辐照在60至180 kGy之间，并使用动态力学分析（DMA）表征物理性质。填料含量和辐射水平对EVA / CF力学性能的影响被评估。观察到剪切应力和模量随填料含量的增加而增加。但是，蠕变柔顺性急剧下降。还显示，由于辐照后聚合物的分子量增加和交联增加，在EVA复合材料上引入辐照会增加剪切应力和动态剪切模量G'的实部。J.乙烯基添加物。TECHNOL。，26：325–335，2020.©2019塑料工程师协会
