ABSTRACT
Recently, hybridization has become a well-known technique to overcome the limitations such as low impact strength, high moisture absorption, and 144 poor durability of single natural fiber reinforced polymer composites. In the present work, hybridization technique is used by incorporating the sisal fibers into jute fiber reinforced epoxy composite in order to study thermal properties. The hybrid composites are prepared by hand lay-up technique with varying weight ratios of fibers keeping constant 30 wt.% as total fibers content. The viscoelastic properties such as storage modulus E, loss modulus (E”), and damping (Tan δ) of prepared hybrid composites are carried out using dynamic mechanical analysis (DMA) at 1 Hz frequency. Thermal stability of prepared composites is studied by thermogravimetric analysis (TGA) whereas differential scanning calorimetry (DSC) is used to measure glass transition temperature (T g ), crystallization temperature (T c ), and decomposition temperature (T d ). The results show that hybrid composite with 50% jute fibers has the higher value of thermal stability, E, E”, and T g .
