In past decades researchers found many difficulties while providing environmentally supportive materials for product making. Natural fibers possess many advantages over synthetic fibers such as ease of availability, bio-degradability, low cost, lesser density, minimal health hazards, and eco-friendly in nature. Natural fiber reinforced polymer composites are the new innovative class of sustainable materials having good mechanical properties for practical applications. Further to increase the performance of a composites, researchers pointed out that using filler materials essentially increases the mechanical properties and in turn minimizes the organic contents in the composite laminates. This literature outlines the effect of natural fillers on the fiber-reinforced polymer matrix composites and also discusses on physical, chemical, thermal, and mechanical properties in terms of XRD, FTIR and SEM characterization. The main motive of this article is to discuss the different combinations of materials along with natural fillers and to assess their suitability for potential engineering applications.
