Carbon nanotubes (CNTs) were dispersed within polyester resin to improve the thermal properties and to understand the degradation mechanism and reaction kinetics of jute reinforced composite. Viscoelastic behavior via dynamic mechanical analysis, strain rate effect and hygrothermal behavior of CNT filled jute composite were studied. The crystallization kinetics and microstructures were investigated with differential scanning calorimeter (DSC), X-ray diffraction (XRD) and scanning electron microscopy (SEM), respectively. Multiwalled CNT with 0, 1 and 3wt% was added within polyester resin matrix, whereas around 70% volume fraction of jute fiber is maintained in each sample. In dynamic mechanical analysis (DMA), 3% CNT filled composite showed better storage modulus and loss modulus values before the hygrothermal test. Due to the exposure to temperature (80°C) and relative humidity (95% RH) for 15 days in environment chamber, both storage and loss modulus of this composite reduced by around 10%.
