ABSTRACT

In this study, biocomposites fibers (flax/epoxy) with different fiber ratios were manufactured and their tensile, 3-point bending and morphological properties were characterized. The interfacial binding of fractured composite samples after tensile and 3-point bending tests were examined by scanning electron microscopy (SEM). The mechanical results revealed an increase in the composite sample manufactured by second formulation CT090 (biocomposites UD [0/90°]_s treated by NaHCO₃) compared to the different formulations studied. For example, the stress and Young’s modulus values of qua-static traction of the biocomposite CT090 treated with sodium bicarbonate are obtained to be 70.13 MPa and 1420.47 MPa, respectively. The overall test results stated that bio sodium carbonate treatment enhanced the mechanical and morphological properties of the biocomposites in this study. Finally, the experimental results were subjected to a one-way analysis of variance (ANOVA) using MINITAB software.

摘要

在这项研究中，制造了具有不同纤维比例的生物复合纤维（亚麻/环氧树脂），并对其拉伸、三点弯曲和形态特性进行了表征。通过扫描电子显微镜（SEM）检查拉伸和三点弯曲试验后断裂复合样品的界面结合。机械结果显示，由第二种配方 CT090 制造的复合样品增加（经 NaHCO _{3处理的生物复合材料 UD [0/90°] s}) 与所研究的不同配方相比。例如，用碳酸氢钠处理的生物复合材料CT090的准静态牵引应力和杨氏模量值分别为70.13 MPa和1420.47 MPa。总体测试结果表明，生物碳酸钠处理增强了本研究中生物复合材料的机械和形态特性。最后，使用MINITAB软件对实验结果进行单因素方差分析（ANOVA）。
