Thermal and dynamic mechanical analysis of hybrid jute/sisal fibre reinforced epoxy composite

The aim of the present study is to investigate the dynamic mechanical and thermal properties of hybrid jute/sisal fibre reinforced epoxy composites. The hybrid composites were prepared by hand layup technique having total fibre loading of 30% by weight with different weight ratios of jute and sisal fibres. Dynamic mechanical properties such as storage modulus (E'), loss modulus (E) and damping (Tan) were investigated in the temperature range of 30-200?. The thermal stability of the prepared composites was studied using thermogravimetric analysis. Other thermal properties such as glass transition temperature (T-g), crystallization temperature (T-c) and decomposition temperature (T-d) were also obtained by differential scanning calorimetry. The results indicated a positive effect of hybridization in terms of increase in dynamic mechanical and thermal properties. Storage modulus, loss modulus and T-g were found to be higher for hybrid composite having a higher percentage of jute fibres.
