Abstract


This paper experimentally investigated the tensile behaviors of hybrid composite structures containing different concentrations of Banana and Sponge Gourd fibres (BF and SGF) for Hockey stick application. The weight percent of 5, 10, 20 and fibre size of 150µm, 300µm and 600µm were used in this research. The design of the experiment was done via Taguchi robust design. `The effects of hybrid concentrations on the tensile behaviors were also investigated. The structural analysis of the developed natural hybrid composite was done using scanning electron microscopy (SEM). The natural hybrid composites demonstrated excellent tensile behaviors at different concentrations of the reinforcements with maximum ultimate tensile strength of 79 MPa obtained by 10%wt Ba, 10%wt Sg natural hybrid composite at 150um fibre size. The natural hybrid composite recorded higher strength than the epoxy resin matrix. The improvements of mechanical properties are guaranteed by the distribution of BF and SGF in the epoxy resin matrix as evidenced in the microstructural analysis.

KEYWORDS: Epoxy resin, Banana Fibre, Sponge Gourd Fibre, Tensile behaviors.
