Study on engineering properties of bamboo fiber/biochar reinforced epoxy composites rod

In recent years, natural fibers have gained more significance in a variety of civil and industrial applications, such as concrete, beams, and slabs. In addition to producing bamboo fiber reinforced epoxy 16 mm diameter biocomposites rod and biochar filler reinforced epoxy biocomposites, this study used compressive molding. Using the stacking sequence RC, RFC, R1-C, R2-C, and R3-C, five different composite rods were created with 35 weight percent (wt%) BF and BC wt% levels of 1%, 3%, and 5% biochar filler substituted with 65% epoxy. Accordingly, studies on bamboo biocomposite rods using various weight-to-content ratios of biochar filler and fiber have been conducted. To further assess the biocomposites rod, mechanical, physical morphology, and water absorption tests were performed. The results demonstrated that the rod morphologies (SEM) of the filler-reinforced biocomposites rod enhanced the fiber-to-resin bonding, which enhanced the mechanical and physical properties. Compared to the other four biocomposites, the R2-C biocomposite, which contains 3 wt% biochar filler and 35 wt% bamboo fiber, exhibits superior mechanical qualities, including outstanding compressive (84.62 N/mm²), tensile (37.1 MPa) and flexural (62.5 MPa) strength. The density results also showed that R2-C biocomposite had the highest density (1.26 g/cc). This investigation recommended the possibility of introducing bio-fiber obtained from waste agricultural residues into biocomposite rods.
