Investigations on Thermal Conductivity of Palm Fibre Reinforced Polyester Composites

Kenaf fiber reinforced polylactic acid green composites possess mentionable thermal and acoustic insulating properties. Sound transmission and sound absorption coefficients are the minimum required necessary parameters for predicting the acoustic properties while thermal conductivity is alone sufficient for predicting the thermal behavior of natural fiber reinforced green composites. In the present chapter, the effect of utilizing different types of kenaf fiber mats and their chemical treatment (sodium acetate) on the thermal and acoustic properties of developed composites is presented. The results showed that the thermal conductivity of developed composites increased with chemical treatment concentration and treatment time. Additionally, the geometry of kenaf fiber mats also influenced the thermal and acoustic properties of developed composites.

“…Both materials (straw and palm fibers), allowed the movements of air to the rooms. The palm fiber has a very high specific heat capacity of 27.1 kJ/kg K and very low thermal diffusivity of 0.21(× 10 −7 m 2 s −1 ) ( Table 1) which enhance good insulation characteristics and passive design [20][21][22].…”

This study examines the impact of thermal performance of Yoruba compound house on the user’s lifestyle to cope with discomfort hours. A compound house was simulated using Autodesk Ecotect software. The study found that the front and right sides of the building have the lowest temperatures due to the combined effects of indirect and interzonal heat transfers. The research highlighted that while the user’s lifestyle in the Yoruba compound house relies on the veranda to cope with discomfort hours, residents of multi-dwelling compound houses rely on a lifestyle of housing adjustments. The study concludes that the thermal properties of the Yoruba compound house are complemented by the user’s lifestyle to cope with the discomfort hours.

“…Experimental results showed that the WPC thermal conductivity decreases with the filler content and WF content. Mohapatra et al [10] determined the thermal conductivity of the palm fibre reinforced polyester composites at different volume fractions of the fibre experimentally by using Lee's apparatus. The experimental results showed that the thermal conductivity of the composite increases with increase in fibre percentage.…”

In the present work, the effective thermal conductivity of teak wood dust (TWD) filled epoxy composites at different volume fractions (6.5, 11.3, 26.8 and 35.9%) have been determined experimentally by using Lee's Apparatus. Composites of teak wood dust particles of 150µ, 200µ and 250µ sizes with varying volume fractions (6.5, 11.3, 26.8 and 35.9%) have been developed by hand lay up technique. From the tests it is observed that for each size of TWD, the thermal conductivity values of composites decreases with increase of filler content which indicates that the TWD reinforced epoxy composites have good insulation properties. It has also been found that the composite with 150µ particle size of teak wood dust at same volume fractions exhibited lowest thermal conductivity compared to composites with 200µ and 250µ of teak wood dust. Therefore the composite with particle size 150µ at 35.9% volume fraction teak wood dust may be more suitable for insulation applications. Experimental results (TWD,150µ) are also compared with the theoretical models (such as Rule of Mixture model, Russel model, Maxwell model Baschirow & Selenew model) and found that the errors associated with all the above four models with respect to experimental ones lie in the range of 20.14 to 84%, 74 to111.84%, 79.13 to 115.79% and 60.13 to 102% respectively.
