In this article, with the aim of promoting sustainability, contributing to the circular economy and the fight against climate change, the production of composite materials from Bio-polyethylene reinforced with corn stover fibers has been studied. The behavior of the materials obtained has been studied experimentally and by mathematical models of micromechanics. The composite materials were produced by extrusion and then injection with from 10 to 50 wt.% of fibers. The creation of a good fiber-matrix interface was studied by the incorporation of coupling agent between (0-8 wt.%). Increase of 131.2% on tensile strength for 40wt.% reinforcement was achieved by adding 6 wt.% of coupling agent. The correct interface was demonstrated by a correlation of 0.99 between the experimental results and the results of the mathematical models used.
在本文中，为了促进可持续发展，助力循环经济以及应对气候变化，对用玉米秸秆纤维增强的生物聚乙烯制备复合材料进行了研究。通过实验和微观力学数学模型对所得材料的性能进行了研究。复合材料通过挤出制备，然后注塑含有10%至50%（重量）纤维的材料。通过加入（0 - 8%重量）的偶联剂研究了良好纤维 - 基体界面的形成。加入6%重量的偶联剂后，40%重量增强材料的拉伸强度提高了131.2%。实验结果与所用数学模型结果之间0.99的相关性证明了正确的界面。
