ABSTRACT

This study used volume fraction of the hybrid fiber, coupling agent and coir/plantain fiber ratio as the control factors for determining the optimum thermal properties of coir/plantain hybrid fiber reinforced polyester composites. Taguchi design technique was adopted in preparing the samples, investigating the signal-to-noise ratio (S/N ratio) for the quality characteristic of the control factor levels required to optimize each thermal property of the samples using Minitab 17. Thermal tests were carried out on the samples of coir/plantain empty fruit bunch (CEFB) hybrid and coir/plantain pseudo stem (CPS) hybrid fiber reinforced polyester composite respectively, after determining the volume fraction of the treated hybrid fiber. The thermal optimum values of the control factors were established for CEFB hybrid fiber reinforced polyester composite and CPS hybrid fiber reinforced polyester composite. CEFB hybrid fiber reinforced polyester composite has the optimum thermal conductivity of 0.3016W/m-K, optimum linear thermal expansion of 10.6070 x 〖10〗^(-5) /℃ and optimum specific heat of 2641.51 J/kg-K; while CPS hybrid fiber reinforced polyester composite has the optimum thermal conductivity of 0.2791W/m-K, linear thermal expansion of 10.395 x 〖10〗^(-5) /℃, and optimum specific heat of 2633.10 J/kg-K. The considered control factors add value to the thermal properties of coir/plantain hybrid fibers reinforced polyester composite. The CEFB hybrid fiber reinforced polyester composite offers better thermal properties than that of CPS hybrid fiber.
