Fabrication and Thermal Analysis of Sisal Banana Epoxy Composite Size

Thermal properties of a polymer composite is a function of resin type, fiber type, architecture, fiber volume fraction, direction of heat flow and service temperature. The thermal response of Fiber Reinforced Polymer (FRP) composites plays a critical role in their performance. The objective of this project is to attain better understanding of thermal behavior of a composite structural system through fundamental understanding of thermal behavior conductivities properties and thermal stability. In this project Natural fiber composites were fabricated by hand layup process. LY556 resin and HY951 hardener mixed in the ratio 10:1 was used as matrix. Composites were fabricated using hybrid mixture of sisal and banana. The effective thermal conductivity is determined by using rule of mixtures. The thermal stability was determined by TGA/DTA techniques. Among the fabricated composites, samples with 13% sisal and 11% banana shows higher thermal stability. The sample with sisal 13% and banana 11% showed least thermal conductivity.
