Abstract

Flax fiber mat biocomposites are popular for the reason that they are ecological, light in weight and have better strength. This study created and analyzed flax fiber-reinforced polymer composites with different types of nano-fillers. Eleven composite samples (S1 to S11) are fabricated using an epoxy material. All examples from S2 to S11 included three layers of flax mats, making up 15% of the weight. To improve the mechanical and useful qualities, different nano-fillers like saline-treated Silicon Carbide (SCI), Barium Sulfate (BaSO₄) and graphite were added at amounts of 3%, 5% and 7% of the total mixture. Sample (S1) was made up of 100% matrix. SCI has the highest mechanical and thermal strength of the three nanofillers. Additionally, the maximum mechanical and thermal strength is found in the 5% wt. of nanofiller. Compared to the other 10 biocomposites, the S4 biocomposite, which contains 5% wt. nanofiller and 3 layer flax fiber mat, demonstrates excellent compressive (111.2 MPa), tensile (81.9 MPa) and flexural (102.4 MPa) strength.
