A comprehensive review on the effect of synthetic filler materials on fiber-reinforced hybrid polymer composites

In the recent days, the target for researchers and scientists is to develop a material which fulfills the parameters such as lightweightness, manufacturability, durability and low-cost materials. The different polymers were coined for the fabrication of composites due to recyclability, cheaper cost and easy of manufacturing. In order to increase the performance and efficiency, the hybridization was invoked in the composites. Hybridization is a process which enhances the properties of polymer matrix composites by incorporating two or more similar or dissimilar fibers in the same composite material. To overcome the drawbacks in polymer composites, the material is filled with synthetic fillers, which elevates the properties of composites and strengthened the fiber matrix interface. Hence this review aims to outline the effect of different synthetic fillers on polymer composites by means of mechanical, thermal and morphological studies.
