The goal of the present study is to investigate and predict the mechanical properties, including impact strength, elastic modulus, and elongation-at-break of quaternary nanocomposites based on polypropylene (PP)/ethylene–propylene–diene monomer (EPDM)/glass fiber (GL)/graphene nanosheets (GPn) by fuzzy logic. Three parameters in different levels, including EPDM, GL, and GPn, were chosen for combination with a PP matrix. The fuzzy logic surfaces showed that the EPDM rubber and GPn had the main role in the elastic modulus of nanocomposites. The high levels of EPDM content resulted in a considerable increase in impact strength and, generally, the presence of EPDM had no effect on elongation-at-break.

基于聚丙烯的四元纳米复合材料力学性能的模糊逻辑预测

本研究的目的是研究和预测基于聚丙烯（PP）/乙烯-丙烯-二烯单体（EPDM）/玻璃纤维的四元纳米复合材料的机械性能，包括冲击强度、弹性模量和断裂伸长率。 (GL)/石墨烯纳米片 (GPn) 通过模糊逻辑。选择了三个不同级别的参数，包括 EPDM、GL 和 GPn，用于与 PP 矩阵组合。模糊逻辑表面表明，EPDM 橡胶和 GPn 在纳米复合材料的弹性模量中起主要作用。高含量的 EPDM 含量导致冲击强度显着增加，一般而言，EPDM 的存在对断裂伸长率没有影响。
