The effect of reinforcing natural fiber in the form of woven fabric on dynamic mechanical and thermogravimetric analysis was investigated. Further the influence of water molecule interaction on dynamic mechanical analysis of natural fiber composite were studied. Results revealed that basket type and intra-ply hybridized composites enhances the dynamic mechanical properties of the composites due to the enhancement in modulus by the reinforcement, whereas herringbone composites enhance the loss factor of the composites. It was noticed that, irrespective of the weaving architecture and intra-ply hybridization, composite samples immersed in the water for 45 days affects the storage and loss modulus of the composite and to enhance the loss factor. Thermogravimetric analysis carried out on composites revealed that, compared to weaving architecture, the presence of cellulose and hemicellulose in the fiber cell wall influences the thermal properties of the composites.
