Study of mechanical properties on abaca/sisal fibre-reinforced epoxy resin-based hybrid composites

Toxic gas and other environmental risks are created when synthetic fibres are burned or degraded slower than natural fibres. Natural fibres have several advantages, including low density, low cost, high specific characteristics and lower hazards during production. Glass fibre is harmful to human health and environment. The fabrication of natural fibre-based composite is easy and non-toxic. Comparing result is required to ensure the properties. In this regard, ABAQUS simulation findings are compared to mechanical characteristics of a hybridised composite (abaca + sisal) in this study. The top and bottom layers of this hybrid composite are formed of sisal fibres, while the centre layer is comprised of abaca fibres. A variety of fibre orientations (0 degrees, 30 degrees, 45 degrees, 60 degrees, 90 degrees) are used to create these hybrid composites (sisal + abaca). The aforementioned specimen is created by hand layup process. Epoxy LY 556 and hardener LY 951 is acted as adhesive agent. According to the results, 90 degrees oriented fibre composites have higher ultimate tensile properties and % elongation than 0 degrees, 30 degrees, 45 degrees and 60 degrees oriented fibre composites. In terms of flexural strength, 30 degrees, 45 degrees, 60 degrees and 90 degrees oriented fibre composites had the similar value, whereas 0 degrees fibre oriented composites had the lowest value. When equated to another oriented fibre material, the ultimate shear strength of the 60 degrees oriented fibre composite was determined to be higher. It has a much higher breaking load than the other oriented fibre composites (0 degrees, 30 degrees, 45 degrees, 60 degrees and 90 degrees), which have lower breaking loads.
