Abstract

There's a constant need for strong, lightweight polymer composites in the automotive, aerospace, and military industries nowadays. The purpose of this work is to examine the mechanical, tribological, and thermal characteristics of composites made of magnesium powder and Paederia foetida fiber (PFs). In this study, the hot press method was utilized to create PFs/Mg/epoxy composites. PFs have been calculated to be 5 % and 10 % (% vol.) with varying Mg concentrations of 10 %, 15 %, and 20 %, in that order. They underwent analysis and comparison for their tensile strength, bending strength, and thermal and tribological properties. The findings of this study demonstrate that the composite containing 10 % PFs and 15 % Mg (KB sample) provides the maximum tensile strength of 38.17 ± 1.65 MPa, the highest flexural strength of close to 70 MPa, and is heat resistant. As the amount of magnesium powder increases, tribology analysis using mass wear intensity and linear wear intensity tends to be low. When 20 % magnesium is added, composites with a fiber volume fraction of 10 % exhibit better overall characteristics than composites with a fiber percentage of 5 %. Tensile test findings for the composite fracture's morphology indicate a rather robust interaction between PFs-Mg and epoxy. These PFs/Mg composites are a prospective alternative for the automobile sector since they have improved mechanical, thermal, and wear qualities as well as sustainability.
增强的机械和热性能的Paederia foetida纤维-镁/环氧复合材料:汽车和航空航天工业的可持续解决方案
如今,汽车、航空航天和军事工业对坚固、轻便的聚合物复合材料的需求不断增加。本研究的目的是研究由镁粉和白参纤维(PFs)制成的复合材料的力学、摩擦学和热特性。本研究采用热压法制备PFs/Mg/环氧复合材料。在Mg浓度依次为10%、15%和20%的情况下,PFs计算值分别为5%和10% (% vol.)。对它们的拉伸强度、弯曲强度、热学和摩擦学性能进行了分析和比较。研究结果表明,含10% pf和15% Mg (KB试样)的复合材料的最大抗拉强度为38.17±1.65 MPa,最高抗折强度接近70 MPa,具有良好的耐热性。随着镁粉用量的增加,采用质量磨损强度和线性磨损强度的摩擦学分析趋于降低。当镁含量为20%时,纤维体积分数为10%的复合材料整体性能优于纤维体积分数为5%的复合材料。复合材料断裂形貌的拉伸试验结果表明,PFs-Mg和环氧树脂之间存在相当强的相互作用。这些PFs/Mg复合材料是汽车行业的一个有前景的替代品,因为它们改善了机械、热、磨损质量以及可持续性。
