Owing to the high cost of carbon fibres and a necessity for finding alternatives that environmentally friendly, a portion of carbon fibres was substituted by woven jute fibre, with various stacking sequences for military applications. Hot press was used to fabricate the composite and hybrid samples of jute/carbon fibres reinforced polyvinyl butyral film using as a layer. Dynamic mechanical experiments (DMA) were conducted with more focus on the stacking sequences of jute and carbon, with increasing temperature. Results showed that the carbon/jute/carbon (H1) hybrid has the highest storage modulus and loss modulus values compared with other hybrids. Significantly, placing woven jute fibre at the outer layers and carbon fibres at the inner layers provided lower dynamic mechanical properties than that of the hybrids with placing jute at the inner layers. Besides, the damping factor shifts to higher temperatures by hybridization of jute fibres compared with carbon composite. Additionally, glass transition temperature (Tg) obtained from the damping curve and loss modulus exhibits a temperature between 129 and 180℃ for all composites, in withstanding dynamic loads. The dynamic mechanical properties were observed to be decreased with increasing temperature for all laminated composites. From results, it could be deduced that it is possible to reduce amount of carbon fibres in different composites industries with woven jute, thus providing less both cost and harmful environment.
