This article focuses on investigating the dynamic behavior of hybrid composites involving natural fibers. The objective of this study is to examine and evaluate the effectiveness of recently used hybrid composite materials. The primary materials utilized are glass fiber-reinforced plastic. Plastic is applied to the surface of fiber-reinforced epoxy composites. Natural fibers are also used in other materials, polyester-based hybrid composites. The breakage pressure of the double shear test in the first composition has been improved from 1.10 to 1.38 kN. The hardness rating was enhanced from 76.15 to 87.99. The interlamination experimental findings improved from 7.96 to 8.52 kN. The results showed that a hybrid with a 50:50 comparable strand ratio of glass and sisal outscored a hybrid with a small fraction of sisal fiber. The second composite describes the effects of natural filler loading at 5%, 10%, and 15% on the mechanical behavior of a polyester-based hybrid. Materials created in a reputable environment for automotive and marine applications. Both hybrid nanocomposite preparation methods are tested, and the findings are validated. The electrical and mechanical characteristics of the materials are also validated and demonstrated to be superior to other current composites. This study highlights composite materials and technological advances and discusses natural fibers’ rich history and promise in many applications. © 2025 Elsevier B.V., All rights reserved.
