Eco-Friendly Flax Fiber Composites Reinforced with Nanofillers for Enhanced Mechanical and Acoustic Performance
Main Article Content
Abstract
The creation of environmentally friendly materials, such as composites made of flax fiber is crucial in the race to achieve zero net carbon emissions. Impregnating flax fiber with bio-based materials is the first step in the production process. Nanofillers made of silver (Ag), activated carbon (AC) and graphene (Gr) are mixed with epoxy resin using magnetic agitation to guarantee an uniform distribution. This strengthened composite is sandwiched between two flax fiber mat layers. In this study, the optimum nanofiller weight percentages are calculated in several test specimens through Response Surface Methodology (RSM). The combination of 18% wt. AC, 7% wt. Ag and 8% wt. Gr have the best tensile strength as 45.31 MPa. While 12% wt. AC, 5% wt. Ag and 6% wt. Gr have the best noise reduction coefficient as 0.559.
