Abstract
Abstract The Biodegradable fiber- reinforced composites are increasingly developed for energy saving applications in automobile and construction industries with significant ecological advantage. The aim of this study is to explore thermal conductivity, specific heat capacity, and thermal diffusivity of Borassus fruit fiber (BFF) reinforced polyester composites. Biodegradable composites were fabricated with the incorporation of Borassus fruit fiber (BFF) in the polyester resin via hand lay-up technique. The thermal conductivity of samples was measured using a guarded heat flow meter as per ASTM E1530 standards. The results revealed that higher content of BFF can contribute to improve the thermal insulation capability of composite. As fiber content increases, the insulation capability of composites increased. The reduction in thermal conductivity of composite at maximum volume fraction was 23.5% compared to unfilled polyester. The thermal conductivity of composites increased with the increase of temperature. Thermal conductivity, heat capacity and diffusivity of composite at maximum fiber content, were 0.186 w/(m.K), 1.64 (kJ/kg.K) and 1.04e-07 mm2/s, respectively. The results propose that the BFF/polyester composites can be a feasible candidate for energy saving applications that require good thermal insulation properties.
