Varying weight percentages of pineapple leaf fiber were added to phenolformaldehyde (PF) in order to generate a composite material. Using the transient plane source (TPS) technique, the thermal conductivities of the varying weight percentage composites were studied. It was found that increasing weight % pineapple leaf fiber resulted in decreasing thermal conductivity and diffusivity of the composites. The experimental results are compared to results produced by two models (the Rayleigh-Maxwell and ...
The thermal properties of a series of treated and untreated oil palm fiber-reinforced composites were tested at room temperature and atmospheric pressure using the TPS method. Treatment of the composites with varying methods resulted in increases in thermal conductivity, porosity and pore sizes depending on the treatment method used. The dependence of thermal conductivity on temperature was also studied and it was found that the maximum thermal conductivity was at ...
Presently, converting waste into reusable materials is a high priority among researchers. This study presents the idea of recycling the natural rubber (NR) from latex condom waste, for its use as a potential filler in styrene butadine rubber (SBR). To properly understand the SBR material ratio aspect, thermal behaviour monitoring, such as thermal conductivity measurements using the Transient Plane Source method, was performed. A linear increase in thermal conductivity of ...
The thermal conductivity and thermal diffusivity of SRP (sisal-reinforced polyethylene), GRP (glass-reinforced polyethylene), and GSRP (sisal/glass hybrid fibre-reinforced polyethylene) were tested from 120 to 350K. Results showed variances in thermal conductivity values with varying temperatures in materials containing different orientations of sisal fibres. Due to the anisotropic nature of the SRP fibre, there is a difference in the thermal conductivity readings from the parallel to the perpendicular direction. The GRP ...
