Quantitatively Investigating the Effects of Fiber Parameters on Tensile and Flexural Response of Flax/Epoxy Biocomposites

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 degrees](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.

Automated summary

In this study, biocomposite fibers with different ratios were manufactured and characterized for their mechanical and morphological properties. The results showed that biocomposites treated with sodium bicarbonate exhibited improved mechanical and morphological properties. The analysis of variance also supported the experimental results.
