Heat Conduction through Natural Fiber/Carbon Nanotubes Filler Matrix Polymer Composite Slabs: An Experimental and Analytical Comparisons

The latest developments in composite materials are anticipated by green engineering. Materials must be eco-friendly, recyclable, biodegradable, and easy to decompose. Researchers are interested in utilizing natural fibres, fillers, and synthetic active ingredients. Natural fiber-polymer composites can specify certain mechanical properties but are hydrophilic and weak, so they rarely meet the needed thermal properties. Composite material selection depends on the application and the superior properties of the fibre/filler: banana fibre (BF), ice husk (RH) and multi-walled carbon nanotubes (MWCNT). In this research article, a brief discussion of the heat transfer mechanism of composites and the development of energy conduction equation are performed for hybrid natural polymer composite. The maximum thermal conductivity observed for 10BF/10RH/1MWCNT wt.% composite is 0.2694 W/mK. From ANSYS numerical simulation, the temperature distribution along the composite wall temperatures T1 to T8 (inner slab: 353K, interface slab: 333K, and outer slab: 313 K) and along with the maximum internal heat generation (inner Slab: 76.418 W/m2, interface slab: 76.402 W/m2 and exterior slab: 76.285 W/m2) resisted by the polymer matrix composite. Finally, it is concluded that the probe temperature and heat flux experimental and analytical data are identical.
