Abstract
This work develops a hybrid composite material using a bio-epoxy resin matrix reinforced with natural sisal and banana stem fibres. The vacuum-assisted resin infusion technique uses to define the appropriate proportions to guarantee the adhesion of the reinforcement. With the physical-mechanical characterisation of the density of 1041 Kg/mᶟ, a flexural resistance of 160.43 MPa, and Young's modulus of 2.17 GPa, the adhesion evaluated using SEM images (scanning electron microscopy) and shows separation between resin and reinforcement less than 10μm. With these properties, using the Granta Edu Pack tool, conventional materials such as polypropylene(PP), polyester, cellulose acetate, polystyrene (PS), Acrylonitrile Butadiene Styrene (ABS), cardboard and wood were found, with similar properties, and the hybrid biocomposite can replace that.
