The research focusses on the characterization studies of the synthesized ferroelectric ceramic materials and the enhancement in their behavior and properties when these samples are reinforced with bio fibers.

• The X ray diffraction studies of the ceramic samples confirm the polycrystalline nature and the existence of strain which got additional evidence with the optical characterization studies.
• The calorimetric studies conducted indicate enhanced thermal resistance and better fiber/matrix adhesion of the fabricated composites.
• The electrical transport investigations emphasize the hopping mechanism for conduction in the ceramic samples, and the dielectric and impedance spectroscopy results validate the Cole-Cole behaviors. Furthermore, it is even more obvious that reinforcement resulted in higher effective dielectric constant values.
• Dynamic mechanical analysis studies the viscoelastic behavior of the Jute reinforced ceramic-PP composite relating the relevant stiffness and damping character of the fabricated composite. DMA studies conclude the enhanced mechanical properties of the fabricated Jute reinforced ceramic -PP composites. The storage modulus values obtained from the DMA data are further evaluated using the predicted theoretical models. The models implemented are in good agreement with the experimental data obtained.
